- EU register name (INCI)

- CAS number
- 1323833-56-2
What the register lists it for
These are the uses the European Commission’s CosIng register lists for Maltodextrin/VP Copolymer in any cosmetic, hair roles first. They say why a maker might add it, not what it does in one formula, and they aren’t a safety rating.
- Film forming
-
Leaves a thin, continuous film on the hair as it dries. Polymers in gels and foams carry it; the film is what feels like a cast.
Register definition: “Producing (upon application) a continuous film on the skin, hair or nails.”
Where it sits on each label
US labels list ingredients from most to least, except that those at 1% or less may follow in any order. A name near the top is a large part of the formula. A label doesn’t mark where the 1% point falls, so further down, the order says little about how much is in it.
- Rinse-out conditioners 1 label First five names: 0 of 1 Rinse-out conditioners without it
- Stylers 1 label First five names: 0 of 1 Stylers without it
Every label, product by product (2)
- Cécred Hydrating Conditioner Rinse-out conditioner 41st of 50 names
- Mielle Honey & Ginger Styling Gel Styler 9th of 17 names
Each line runs from the first name on a label to the last; a dot is where this ingredient sits. Makers change formulas now and then; if the list on your bottle differs, go by your bottle.
