How much of it is left on hair between washes.

Rinse-out behaviour Rinses clean

What it takes to get it off the hair again.

Role Keeps water-based formulas

What it is in the formula to protect.

What it does for a formula

What Triethyl Citrate 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.

Sets the acidity

The cuticle lies flatter on the acidic side; this is how a formula gets there.

Rinses away easily

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

Charge

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.

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.

DependsFrizz-prone, damaged, or high-friction hair

pH adjusters are how a formula is brought to a chosen acidity, and an acidic formula keeps the cuticle lying flatter than an alkaline one. Which way this one moves the pH depends on the formula, and the finished pH is not on the label.

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 product that keeps over its shelf life
a formula set to the acidity the cuticle prefers
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an exact safety score — we do not publish one, for any ingredient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 conditioners
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, soften the strand, and hold on to water.

How this page was made

Every number above is counted from the ingredient lists in our own product library — 96 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.
