How to Read a Laundry Detergent Label

A detergent label tells you more than the front of the bottle does, once you know where to look. This guide walks through the parts of a label in order: the ingredient list, the signal word, the scent terms and the marketing claims. At the end there is a worked example using a real ingredient list.

Start with the ingredient list

Cleaning products don’t follow the strict ingredient rules that food does, but many brands now list every intentionally added ingredient, and some states require that information to be published. California’s Cleaning Product Right to Know Act, for example, requires manufacturers to disclose intentionally added ingredients online. If the package doesn’t list ingredients, check the brand’s website. A brand that publishes nothing is telling you something too.

When a list is given in order, the first few ingredients usually make up most of the product. In liquid detergent the first ingredient is often water. In a sheet or a powder you will see the active ingredients near the top.

What each type of ingredient does

Long chemical names are easier once you group them by job. Almost every detergent ingredient falls into one of these:

Job What it does Names you may see
Surfactant Lifts soil and oil off fabric and keeps it in the water Sodium lauryl sulfate, alcohol ethoxylate, olefin sulfonate, alkyl polyglucosides
Water softener Stops hard-water minerals from blunting the surfactants Sodium citrate, tetrasodium glutamate diacetate
Enzyme Breaks down specific stains such as protein or starch Protease, amylase, lipase
pH adjuster Keeps the formula at the pH it works best at Citric acid
Film or carrier Holds the dose in a sheet or pod and dissolves in water Polyvinyl alcohol
Solvent Keeps everything mixed Water, glycerin
Fragrance Adds scent “Fragrance” or named components such as linalool
Dye or brightener Changes the color of the product or makes fabric look brighter Colorant names, “optical brightener”

What do Danger, Warning and Caution mean?

Household products that could cause harm if misused carry a signal word. Danger is the strongest, Warning is in the middle and Caution is the mildest. The words come with instructions such as “keep out of reach of children” or “avoid contact with eyes”. Read them, and store every detergent, of any format, where children and pets can’t get to it.

Fragrance free, unscented, free and clear: what is the difference?

Scent terms aren’t defined the same way by every brand, so read the ingredient list as well as the front:

  • Fragrance free usually means no fragrance was added.
  • Unscented means the product has no noticeable smell. Some brands add a masking fragrance to cover the base smell, so check the list for “fragrance”.
  • Free and clear usually means no added fragrance and no dyes. We explain it in full in what free and clear detergent means.

If scent bothers someone in your home, look for named fragrance components in the list. Linalool, for example, is a common fragrance ingredient recognized as a potential skin allergen.

How to read the claims on the front

Claims on the front of a package are marketing. Some are specific and checkable, and some aren’t. A few questions help:

  • Is it specific? “Phosphate free” can be checked against the ingredient list. A vague word with no detail can’t.
  • Does it say what part it means? “Plastic-free packaging” is about the box, not the product inside.
  • Is the load count “up to”? Load counts usually assume the smallest dose. Divide the price by the number of doses you will actually use.
  • Is there a certification? If a logo is shown, look up who issues it and what it covers.

A worked example: our Fresh Meadow sheets

Here is the full ingredient list for Toss & Go Fresh Meadow, grouped the way this guide suggests:

Ingredient Job
Sodium Lauryl Sulfate Surfactant
Polyvinyl Alcohol Copolymer The dissolvable sheet
Water Solvent
Sodium C14-16 Olefin Sulfonate Surfactant
Glycerin Keeps the sheet flexible
Sodium Citrate Water softener
Sodium Methyl Ester Sulfonate Surfactant
Alkyl Polyglucosides Surfactant
Cocamidopropyl Betaine Coconut-derived foam booster
Lauramidopropylamine Oxide Surfactant
Tetrasodium Glutamate Diacetate Water conditioner
C12-18 Alcohol Ethoxylate Surfactant
Citric Acid pH adjuster
Fragrance components Linalool, OTNE, Verdyl Acetate, Dihydromyrcenol, Methyl Dihydrojasmonate

Reading it: the cleaning is done by six surfactants; two ingredients handle hard water; the fragrance is listed by component, including linalool. The Fragrance Free version has a shorter list with no fragrance and no dyes. Both lists, with CAS numbers, are on the Box of 50 page.

Frequently asked questions

What should I look for on a laundry detergent label?

A full ingredient list, the signal word and its instructions, the scent terms, and how many doses the package really holds.

Why does my detergent list “fragrance” as one word?

Brands can group fragrance components under one word. Some list the main components by name, which is more useful if scent matters to you.

Is a shorter ingredient list better?

Not by itself. A short list is easier to read, but what matters is what each ingredient does and whether you need it.

What does “phosphate free” mean?

No phosphates were added. Phosphates were once common water softeners in detergent; most laundry detergents sold in the US no longer use them.
