At a glance
Four named levels, read from this ingredient’s chemical class, its charge, its solubility, or where it sits on the labels we have. More dots means more of the property named — never “better”.
How much of it is left on hair between washes.
What it takes to get it off the hair again.
How much oil it strips, as a class.
The foam the class is known for, not a measured volume.
| Property | Level | Out of |
|---|---|---|
| Buildup risk | Low | 1 of 5 |
| Rinse-out behaviour | Rinses clean | 5 of 5 |
| Cleansing strength | Gentle | 3 of 5 |
| Lather | Creamy | 4 of 5 |
What it does for a formula
What Sodium Methyl Lauroyl Taurate does
The general function first, then how the role changes by product type where we have researched it.
An acyl amino-acid or isethionate detergent: less stripping than a sulfate, creamier foam.
Foam is a feel, not a measure of how clean hair gets.
Water alone removes it, so it does not accumulate between washes.
The mechanism behind every wash: oil pulled off the hair and rinsed away.
Charge
Negatively charged, like the hair surface itself — so it is repelled rather than attracted, rinses away cleanly, and is the charge most detergents carry.
Solubility
Rinses out with water alone — it does not accumulate on hair between washes.

How to read this
US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order.
So position tells you about relative amount only above that line, and we never convert a position into a percentage.
Why it matters to shoppers
What this ingredient is evidence of, what it is not evidence of, and what our own method can and cannot tell you.
- gentle cleansing
- sulfate-free shampoos
- a creamy lather
- a gentler wash that still foams
- an exact safety score — we do not publish one, for any ingredient
- how a finished product performs by itself — that is the whole formula, not one line of it
- the exact percentage in a bottle — label position never converts into a number
- a supporting mild anionic cleanser alongside the main ingredients in our shampoos
- it was on the label of every product we counted — we read printed ingredient lists, not marketing copy
- harshness or irritation
- that a product is right or wrong for you
We do not publish safety scores or hazard grades. Where a regulator has published a restriction or a use condition, we state it and cite it; otherwise we describe what the ingredient does and stop.

How this page was made
- Every number above is counted from the ingredient lists in our own product library — 3 of 3889 researched products list this ingredient. Nothing on this page is written per ingredient.
- The dots are named levels read from an ingredient’s chemical class, charge, solubility, or where it sits on the labels we have — never a score.
- US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Position tells you about relative amount only above that line, and we never convert a position into a percentage.
- The prominence bands (leading, supporting, secondary) are the same ones the product pages use to read a single label, applied here to the median position across a category.
- We do not publish safety scores or hazard grades. Where a regulator has published a restriction or a use condition, we state it and cite it; otherwise we describe what the ingredient does and stop.
- Identifiers and references appear only when a published source is attached to this entry; where none is, the row is simply absent rather than filled in.
- This is cosmetic information, not medical advice, and nothing here diagnoses or treats a health condition.
- Entry last updated 2026-09-02. Product-page methodology: the product library.
