To read cleaning product ingredients, find the list on the back and work top to bottom, because it runs in order of highest amount first. Translate the INCI style chemical names into plain language, sort them by job (surfactant, solvent, acid or alkali, preservative, fragrance), then compare two products on what actually does the cleaning rather than the marketing on the front.
Walk down the cleaning aisle of any Australian supermarket and the front of every bottle promises roughly the same thing: powerful, fresh, tough on grease, kind to your home. The front label is marketing. The back label, the ingredient list, is where the truth lives. Learning to read it is one of the most useful skills a shopper can build, because it lets you compare any two products on their merits and stop paying for a fragrance and a coloured liquid dressed up as a breakthrough.
This guide teaches you that skill from the ground up. It is brand agnostic on purpose. By the end you will be able to pick up two random bottles, scan the backs, and form an honest opinion about which one is actually doing the cleaning, which is mostly water and scent, and which one carries ingredients you would rather avoid. We work with cleaning products every day at HomeKind, and our the HomeKind bench runs on real jobs, so the standards here come from years of looking at what a label promises versus what it does on a real benchtop. We will be honest about where our own choices sit too, but the method works on anyone's bottle, including ours.
Why the ingredient list matters more than the front label
Words like natural, eco, gentle, and plant based are not legally defined cleaning terms in Australia. There is no single regulator stamping a fixed meaning on green or non toxic the way there is for, say, organic food certification. That means the marketing copy on the front can say almost anything, while the only place a manufacturer has to be specific is the ingredient list.
So the front sells you a feeling. The back tells you the recipe. Once you can read the recipe, the feeling becomes optional. You will notice that many premium and budget products share an almost identical core of ingredients, which is a fast way to understand where your money is really going. When you run a cleaning business and you are buying product by the carton, you stop reading the brave words on the front within a week, because the bottle that actually shifts a greasy rangehood is rarely the one with the loudest claims. The list is what survives contact with real work.
What you are legally entitled to see
Cleaning product ingredient disclosure in Australia is less strict than for cosmetics or food. Many brands list ingredients voluntarily, some list them in full, and some only name a few headline components. A brand that prints a complete, plain ingredient list is showing you confidence. A brand that hides behind a single line like surfactants and fragrance is asking for trust it has not earned. When a list is missing, that absence is itself information.
The one rule that does most of the work: order equals amount
Ingredient lists are written in descending order by quantity, highest first, just like food labels. This single rule tells you most of what you need to know.
For almost every spray and liquid cleaner, the first ingredient is aqua, which is simply water. That is completely normal and not a criticism. The interesting question is what comes after the water, because those next few ingredients are the ones doing the real work. The further down the list something sits, the less of it is in the bottle.
This is exactly why concentrates change the maths. A ready to use spray is mostly water you are paying to ship and store. A concentrate strips the water out so you add it yourself at home from the tap. Our own All in One Cleaner Concentrate is built on that idea: one 1L bottle, diluted at 5 to 10ml per litre for everyday cleaning, makes up to 100 standard spray bottles, which works out to roughly 40c a bottle rather than the $5 to $7 you might pay for a pre mixed supermarket spray.
Reading a concentrate's list (a rule you can apply anywhere)
Here is a teaching point that trips up most people, and it applies to any concentrate, not just ours. On a concentrate, the dilution water you add later is not printed on the list, because it is not in the bottle yet. That pushes the surfactant and the other active ingredients much higher up, sometimes right to the top where water would normally sit. This does not mean a concentrate is harsher or stronger per spray than a ready to use bottle once you have diluted it. It simply means you cannot compare list positions across the two formats directly.
So the rule is this: only compare a concentrate against another concentrate, and a ready to use spray against another ready to use spray. If you want to compare across formats fairly, mentally dilute the concentrate first, or just compare the relative order of the working ingredients rather than their exact rank. A surfactant sitting second on a concentrate is not automatically more aggressive than the same surfactant sitting fourth on a diluted spray. Position tells you ratio within that bottle, not absolute strength on your surface.
The five jobs every ingredient is doing
A cleaning formula is a small team, and every ingredient has a job. Once you can sort an unfamiliar list into these five buckets, even a long intimidating list becomes readable. Almost everything you will meet falls into one of these roles.
| Job | What it does | Names you will see |
|---|---|---|
| Surfactant | Lifts grease and dirt off surfaces so water can rinse it away. The core cleaning agent. | Anything ending in glucoside, sulfate, or sulfonate; coco glucoside, decyl glucoside, sodium lauryl sulfate. |
| Solvent | Dissolves oily or sticky residue that water alone cannot shift. | D limonene, ethanol, isopropyl alcohol, glycol ethers. |
| Acid or alkali (pH agent) | Tunes the formula for the mess. Acids cut limescale and soap scum; alkalis cut baked on grease. | Citric acid, lactic acid, sodium citrate, sodium hydroxide, sodium bicarbonate. |
| Preservative | Stops mould and bacteria growing in the bottle so it lasts on the shelf. | Sodium benzoate, potassium sorbate, benzisothiazolinone, methylisothiazolinone. |
| Fragrance and colour | Smell and appearance only. No cleaning value. | Parfum, fragrance, essential oil names, CI followed by numbers, synthetic dyes. |
There are a few supporting players too, such as thickeners (hydroxyethyl cellulose, xanthan gum) that control how runny the liquid is, and enzymes, which we will cover separately because they behave differently from a standard surfactant.
How to translate INCI style names into plain language
INCI stands for the International Nomenclature of Cosmetic Ingredients, a standardised naming system that also shows up on many cleaning labels. The names look intimidating but they follow patterns. Once you know the patterns you can decode most of a list without looking anything up.
Surfactant clues: the suffix tells the story
- Ends in glucoside (coco glucoside, decyl glucoside, lauryl glucoside): a sugar based plant surfactant, usually derived from coconut or corn, generally mild.
- Ends in sulfate (sodium lauryl sulfate, sodium laureth sulfate): a strong foaming surfactant. Effective and not dangerous in a rinse off product, but a common irritant some people choose to avoid.
- Coco or cocamido at the start (cocamidopropyl betaine): coconut derived, mild, often used to soften harsher surfactants.
Acid clues (the descaling and soap scum side)
- Citric acid and sodium citrate: from citrus, excellent on limescale, hard water marks and soap scum. Sodium citrate is the gentler salt form.
- Lactic acid: a mild acid good on mineral build up, also helps with that streak free finish on glass.
- Acetic acid: the active part of vinegar.
Alkali clues (the baked on grease side)
Acids and alkalis sit at opposite ends of the pH scale and they solve opposite messes, so reading for the alkalis is just as important. An acid heavy formula is built for limescale, soap scum and hard water marks in bathrooms. An alkali heavy formula is built for baked on grease, oven residue and oily kitchen grime. Watch for these names:
- Sodium bicarbonate: mild alkali, the baking soda you already know, gentle on grease and odours.
- Sodium carbonate (washing soda): a stronger alkali that cuts heavier grease.
- Sodium hydroxide or potassium hydroxide: strong caustic alkalis found in serious oven and drain products. Very effective, but the harsh end of the scale, and the kind of thing many shoppers reading this guide are trying to move away from for everyday wiping.
- Sodium metasilicate: a heavy duty degreasing alkali seen in industrial cleaners.
So if you turn over two bottles and one leans on citric and lactic acid while the other leans on sodium carbonate and a hydroxide, you are not looking at better versus worse. You are looking at a descaler versus a degreaser, two different tools. Knowing which is which from the prose alone is the difference between buying for your bathroom and buying for your oven.
Solvent clues
- D limonene: the oil pressed from citrus peel. A genuinely effective natural degreaser and a common source of citrus scent. Worth noting it can be an irritant for sensitive skin in concentrated form, which is honest nuance rather than alarm.
- Anything with glycol or ether: petroleum derived solvents. Effective, but the kind of thing many shoppers reading this guide are trying to step away from.
Preservative clues
- Sodium benzoate and potassium sorbate: widely used, also found as food preservatives. Look for food grade noted on the label.
- Names ending in isothiazolinone (methylisothiazolinone, benzisothiazolinone): effective preservatives that are also among the more common contact allergens. Many sensitive skin sufferers specifically watch for these.

Why 'free from' claims are marketing too
One of the easiest traps to fall into is treating a list of 'free from' badges as proof a product is clean. A label can shout no SLS, no parabens, no phosphates in big letters on the front and still carry an ingredient you personally avoid, such as a strong isothiazolinone preservative or an undisclosed fragrance, because none of those are SLS, parabens or phosphates. A 'free from' claim only tells you about the specific things it names. It says nothing about everything it does not name.
This is the honest part, and it applies to us as much as anyone. HomeKind says no synthetic dyes, no phosphates, no parabens, no SLS. Those are true and they matter, but you should still read our full list the same sceptical way, sort it into the five jobs, and check it against your own avoid list rather than taking the badges at face value. A 'free from' line is a starting point for your reading, never a replacement for it. The whole skill of this guide exists precisely so the front of any bottle, including ours, cannot do your thinking for you.
A worked example: reading two bottles side by side
Here is the method in action. Imagine you pick up two all purpose sprays. Do not read the front. Turn them over.
Bottle A lists: aqua, sodium laureth sulfate, cocamidopropyl betaine, glycol ether, fragrance, methylisothiazolinone, CI 42090 (a blue dye).
Bottle B lists: aqua, coco glucoside, sodium citrate, D limonene, lactic acid, potassium sorbate, lemon myrtle oil.
Now sort each into the five jobs. Bottle A is built on a sulfate surfactant with a petroleum solvent, an isothiazolinone preservative, synthetic fragrance and a blue dye. It will clean well. It also carries three of the things sensitive shoppers most often avoid. Bottle B is built on a sugar based surfactant, a citrus acid for hard water, a citrus solvent for grease, a food adjacent preservative and a single essential oil for scent. Both clean. They are simply built on different philosophies, and now you can see which is which in about twenty seconds rather than trusting the word eco on the front.
Notice too what neither bottle is built for. Both lean on acids and mild surfactants, so both are general purpose and bathroom friendly. Neither carries a strong alkali like sodium carbonate or a hydroxide, which tells you that for a truly baked on oven, you would want a dedicated degreaser instead. Reading the list does not just compare two products, it also tells you when neither is the right tool for the job in front of you.
This is the whole game. You are not memorising chemistry. You are sorting, translating and comparing.
Where enzymes fit, and why they are different
Enzymes are a newer addition to many cleaners and they do not behave like a surfactant. Instead of lifting a mess off a surface, an enzyme breaks the mess down into smaller pieces that rinse away easily. They are catalysts, so a small amount keeps working, which is part of why a little goes a long way.
The three you will most often see, and what each one targets:
| Enzyme | Breaks down | Real world mess |
|---|---|---|
| Protease | Proteins | Food spills, blood, sweat, grass, pet messes. |
| Amylase | Starches | Sauces, gravy, dried food, pasta and potato residue. |
| Lipase | Fats and oils | Greasy benchtops, cooking oil, butter, rangehood film. |
When you see protease, amylase and lipase together on a list, the formula is set up to handle the three main families of household mess biologically rather than relying on aggressive chemistry. Our own concentrate uses that exact enzyme blend alongside plant and coconut glucosides, which is why it can step in for several separate products. If you want the full story on this approach, our guide to how enzyme cleaners work goes deeper.
The fragrance and dye question
Two of the most common reasons people switch cleaners are fragrance sensitivity and a wish to avoid synthetic dyes. Here is how to read for both.
Fragrance or parfum as a single word can legally hide a long list of undisclosed scent chemicals. It is not automatically harmful, but it is opaque, and if you react to scented products it is the line to watch. A formula that instead names its scent source, for example lemon myrtle oil or rosemary oil, is being more transparent about what is creating the smell. A genuinely scent free option will say so plainly and skip the fragrance line entirely.
Colour shows up as parfum's visual cousin: CI followed by a five digit number, or words like dye or colourant. Cleaning liquid does not need to be blue or pink to work. The colour is purely aesthetic. If you are minimising additives, an uncoloured formula removes one ingredient that serves no cleaning purpose at all.
This is one area where we made a deliberate choice. HomeKind uses essential oils for scent across four options, Lemon Myrtle and Eucalyptus Radiata, Mandarin Peel and Rosemary, Peppermint and Pine Needle, plus a Fragrance Free version for anyone who wants nothing added, and we use no synthetic dyes. The formula is identical across all four, so scent is the only variable. For more on choosing, see our note on picking a cleaning scent for a sensitive household.
Reading for the environment: septic, greywater and what drains away
What you clean with ends up down the drain, and for many Australian households that drain leads to a septic system or onto a garden as greywater. The ingredient list helps you read for this too.
Phosphates were once common water softeners in cleaners and detergents. They are effective but contribute to algal blooms in waterways, which is why many shoppers and councils encourage phosphate free choices. A label that states no phosphates is responding to exactly this concern.
Harsh preservatives and biocides can disrupt the bacterial balance a septic tank relies on to function. Gentler, food adjacent preservatives like sodium benzoate and potassium sorbate are generally a friendlier choice for a septic household, though no cleaner should be poured down a drain in large concentrated amounts.
If a brand specifically states it is septic and greywater safe, as ours does, that is a claim you can sanity check against the ingredient list using everything above. We cover the full topic in septic safe cleaning at home and choosing greywater safe products.
A simple step by step you can use in the aisle
- Ignore the front. Turn the bottle over and find the ingredient list.
- Note the first ingredient. It is almost always water, which is fine. The action starts at ingredient two. On a concentrate the actives sit higher, so adjust your expectations for that format.
- Find the surfactant. Scan for a glucoside, sulfate or sulfonate. This is the main cleaning agent.
- Read the acid or alkali. Acids (citric, lactic) point to a descaler for bathrooms and hard water. Alkalis (sodium carbonate, a hydroxide) point to a degreaser for baked on grease. This tells you what job the bottle is really for.
- Sort the rest into the remaining jobs. Solvent, preservative, fragrance and colour. Most lines will fall into place quickly.
- Flag your personal avoid list. Whether that is sulfates, isothiazolinone preservatives, synthetic dyes, phosphates or undisclosed fragrance, you now know the words to look for, and you know not to trust the 'free from' badges alone.
- Compare like for like. Hold two bottles up and compare surfactant to surfactant, preservative to preservative, concentrate to concentrate. The better product for you is now obvious.
The first few times this takes a minute. After a dozen bottles it takes fifteen seconds, and you will never read a cleaning label the same way again.
When reading the list is not the right fix
Honesty matters here, so a few caveats. Reading ingredients tells you what is in a product, not how well it performs or how concentrated each ingredient is. A formula can list all the right plant based ingredients and still underperform if they are present in tiny amounts. The list is a strong filter, not a performance guarantee. Real world testing in your own home is still the final word.
The list also will not tell you everything about safety in absolute terms. Dose, concentration and how you use a product all matter. A natural ingredient is not automatically safe at any concentration, and a synthetic one is not automatically dangerous. D limonene, a plant derived solvent, is a good example of a natural ingredient that some people still react to. Treat the list as a tool for informed comparison, not as a pass or fail moral test.
Finally, if you or someone in your home has a diagnosed sensitivity or allergy, the ingredient list is a starting point for a conversation with a healthcare professional, not a substitute for one. Use it to narrow your choices, then patch test and pay attention to how your home and skin actually respond.
Bringing it together
The skill you have just built is permanent and brand neutral. It works on the most expensive boutique cleaner and the cheapest supermarket spray equally well. Order equals amount, every ingredient has one of five jobs, the names follow decodable patterns, acids and alkalis point to different messes, and the real comparison is surfactant to surfactant, not front label to front label.
When we built our own All in One Cleaner Concentrate at HomeKind, we designed it to survive exactly this kind of scrutiny: plant and coconut glucosides doing the cleaning, a protease, amylase and lipase enzyme blend for everyday mess, citrus acids for hard water and a streak free finish on glass and mirrors, food grade preservatives, essential oils for scent, no synthetic dyes, no phosphates, no parabens, no SLS. One 1L bottle replaces your all purpose, glass, bathroom and floor cleaners and makes up to 100 spray bottles, it is septic and greywater safe, and the bottle is recyclable. The concentrate is in stock now with orders open now, so you can buy today and it is posted same day if you order before 1pm, otherwise the next business day. Read our list the same way you would read anyone's. That is rather the point.
For the bigger picture, this article sits inside our pillar guide, plant based and non toxic cleaning in Australia, which ties all of these threads together.
