What it does for a formula

What Potassium Sorbate does

The general function first, then how the role changes by product type where we have researched it.

Keeps the formula stable

Anything with water in it needs one, over the life of the bottle.

Rinses away easily

Water alone removes it, so it does not accumulate between washes.

Charge

Anionic (negatively charged)

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

Water-solubleOil-solubleWater-dispersibleInsolubleVolatile

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.

A good sign if you want

a product that keeps over its shelf life
a rinse-clean feel

Less relevant if you want to know

an exact safety score — we do not publish one, for any ingredient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

Seeing it usually means

a secondary preservative, listed below the main ingredients in our shampoos
it was on the label of every product we counted — we read printed ingredient lists, not marketing copy

It does not automatically mean

that the product would be better without one
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We do not publish safety scores or hazard grades.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.

Commonly paired with

Ingredients that appear alongside this one most often in our library. Near-universal ingredients are excluded — they pair with everything and tell you nothing.

The number beside a name is how many products in our library list both.

These ingredients tend to appear together to carry the formula and let it dry, deliver a stated effect, and improve feel after rinsing.

How this page was made

Every number above is counted from the ingredient lists in our own product library — 1040 of 4008 researched products list this ingredient. Nothing on this page is written per ingredient.
The dots are levels, not scores. Each one is read from what kind of ingredient it is — its chemical class, its charge, its 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; 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.
