At a glance
Four things worth knowing about how this ingredient behaves on hair.
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 |

| Rinse-out behaviour | Rinses clean | 5 of 5 |
| Cleansing strength | Very gentle | 2 of 5 |

What it does for a formula
What Cocamidopropyl Hydroxysultaine does
The general function first, then how the role changes by product type where we have researched it.
A betaine-type surfactant, paired with an anionic to lower irritation and build foam.
Added alongside a stronger detergent to build foam and take the edge off it.
A milder detergent class, used where a formula avoids sulfates.
Water alone removes it, so it does not accumulate between washes.
Charge
Carries a positive or a negative charge depending on the pH around it, which is why amphoteric ingredients are used to soften harsher cleansers.
Solubility
Rinses out with water alone, so it does not build up 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.
Who should pay attention
Formulation guidance for specific hair conditions, limited to the label positions where it applies. It is not a conclusion about any finished product, or about you.
Mild cleansing leaves more surface lubrication in place on hair that dries out quickly.
One of the mildest detergent classes. It is usually there to let a formula lather without a harsher detergent doing the work.
The mildest detergents are also the least complete: a routine that deposits films needs something stronger periodically.
Read from this ingredient’s chemical class. Where we have researched the ingredient itself, that reading replaces the class one.
Why it matters to shoppers
What seeing this ingredient tells you, what it does not, and the limits of our own method.
- the mildest cleansing
- a formula built for daily washing
- a milder feel from a cleanser blend
- foam without a harsher detergent
- an exact safety score (we do not publish one for any ingredient)
- how a finished product performs, which depends on the whole formula, not one line of it
- the exact percentage in a bottle, because label position never converts into a number
- a supporting amphoteric cleanser alongside the main ingredients in our shampoos
- it was on the printed ingredient list of every product we counted (we read labels, not marketing copy)
- that the product cannot clean properly
- 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: 307 of 6816 researched products list this ingredient. Nothing on this page is written per ingredient.
- The dots are levels, not scores. Each one comes from what kind of ingredient it is (its chemical class, charge and solubility) or from where it sits on the labels we have.
- 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. Without one, we leave the row out rather than fill it in.
- This is cosmetic information, not medical advice, and nothing here diagnoses or treats a health condition.
- Entry last updated 2026-09-22. Product-page methodology: the product library.
