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.
Whether hair pulls it in or pushes it away, read from its charge.
How much easier it makes a comb pass.

What it does for a formula
What Cetrimonium Chloride does
The general function first, then how the role changes by product type where we have researched it.
Positive charge is drawn to the negatively charged, worn patches of a strand.
The measurable part of conditioning: less force to pull a comb through.
Water alone removes it, so it does not accumulate between washes.
Positive charge holds it on the hair through the rinse.
Charge
Positively charged, so it is drawn to the negatively charged, damaged areas of hair and stays behind after rinsing. That is why conditioning happens where the wear is.
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.
The C16 quat binds mostly by charge rather than by chain, so it deposits measurably less than the C22 ones. Less deposit is less conditioning and also less weight, which is usually the trade fine hair wants.
A cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.
Substantive by design. A routine with no detergent wash gives it nothing to leave with.
Every detergent removes some sebum along with the product it is there to wash out. Which detergent it is matters more than that there is one.

Why it matters to shoppers
What seeing this ingredient tells you, what it does not, and the limits of our own method.
- detangling
- thick or coarse hair
- detangling and less breakage from combing
- a rinse-clean feel
- an exact safety score (we do not publish one for any ingredient)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 secondary conditioner, listed below the main ingredients in our conditioners
- it was on the printed ingredient list of every product we counted (we read labels, not marketing copy)
- it is meant to stay on the hair rather than rinse away
- 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: 1512 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.
