Steareth-10 allyl ether/acrylates copolymer is a copolymer of the allyl ether of steareth-10 (a polyethylene glycol ether of stearyl alcohol) with one or more monomers of acrylic acid, methacrylic acid or their simple esters. CosIng lists it as a film-forming and viscosity-controlling ingredient.
Where it is used
Found in a small number of products, such as creams, gels and hair care products.
Limits of interpretation
The INCI list shows which ingredients are present, not how much of each. Above 1%, ingredients are listed in descending order of weight; below 1% the order is free.
The INCI name does not show which acrylic monomers were used or in what proportions.
