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”.
How much of it is left on hair between washes.
What it takes to get it off the hair again.
What the polymer class can do, not what any bottle claims.
How well the film survives damp air, as a class.

| Buildup risk | Low | 2 of 5 |
| Rinse-out behaviour | Rinses with shampoo | 4 of 5 |

What it does for a formula
What Capryloyl Glycerin/Sebacic Acid Copolymer does
The general function first, then how the role changes by product type where we have researched it.
The film is what holds a shape once the water has gone.
How firmly depends on the polymer class and how much of it is used.
Smooths the feel of the strand without adding hold or cleaning.
It does not truly dissolve, and ordinary shampooing removes it.
Charge
Charge is not recorded for this ingredient.
Solubility
Spreads through water without truly dissolving, and normal shampooing removes it.

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.
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
How rigid the finish is depends on which polymer it is and what the formula pairs with it, not on there being one.
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 style that holds
- a softer feel
- a product ordinary shampooing removes
- less frizz and easier combing
- an exact safety score — we do not publish one, for any ingredient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
- a secondary film former, listed below the main ingredients in our leave-ins
- it was on the label of every product we counted — we read printed ingredient lists, not marketing copy
- 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.

The number beside a name is how many products in our library list both.
These ingredients tend to appear together to soften the strand, improve feel after rinsing, and carry the formula and let it dry.

How this page was made
- Every number above is counted from the ingredient lists in our own product library — 86 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.
- Entry last updated 2026-08-28. Product-page methodology: the product library.
