What it does for a formula
What C10-11 Isoalkane does
The general function first, then how the role changes by product type where we have researched it.
What everything else is dissolved in before it reaches your hair.
Smooths the feel of the strand without adding hold or cleaning.
It carries the formula onto the hair and then leaves.
Charge
Charge is not recorded for this ingredient.

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 seeing this ingredient tells you, what it does not, and the limits of our own method.
- a light, fast-drying formula
- a softer feel
- nothing left on the hair
- an exact safety score (we do not publish one for any ingredient)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 supporting solvent alongside the main ingredients in our hair oils
- it was on the printed ingredient list of every product we counted (we read labels, not marketing copy)
- it is a carrier, not something left on the hair
- 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We do not publish safety scores or hazard grades.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 give it a scent, firm up damaged areas, 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: 5 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.
- This is cosmetic information, not medical advice, and nothing here diagnoses or treats a health condition.
- Entry last updated 2026-09-22. Product-page methodology: the product library.
