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”.

Buildup risk Needs a cleanser

How much of it is left on hair between washes.

Rinse-out behaviour Rinses with a cleanser

What it takes to get it off the hair again.

Declaration Named allergen

What it does for a formula

What Linalool does

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

Gives it a scent

A declared blend: the individual components are not named unless rules require it.

A named scent component

EU rules require this one to be listed by name rather than inside "fragrance".

Stays until washed

It takes a surfactant to remove — worth knowing on a low-detergent routine.

Charge

Solubility

Needs a surfactant to remove. On a low-detergent routine it can build up over time.

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

Conditional formulation guidance, scoped to a hair condition and to the positions where it is meaningful. It is not a conclusion about any finished product, and not a conclusion about you.

May not suitFragrance-sensitive routines

One of the 26 scent components the EU requires to be named individually above a threshold. It is named because it is a known contact allergen, not because it is unusual.

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 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 scented product
scent components named individually
something that lasts through the day

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an exact safety score — we do not publish one, for any ingredient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 fragrance, 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 will suit you if you react to scent
that it is riskier than the unnamed components of a fragrance blend
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 give it a scent, carry the formula and let it dry, and improve feel after rinsing.

How this page was made

Every number above is counted from the ingredient lists in our own product library — 1462 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.
