The Basics On Acrylates/Dimethicone Copolymer
What is Acrylates/Dimethicone Copolymer?
A graft copolymer of acrylic polymer and dimethylpolysiloxane dissolved in volatile dimethicone.
What are other names for Acrylates/Dimethicone Copolymer?
ACRYLATE-DIMETHICONE COPOLYMER, ACRYLATES/ DIMETHICONE COPOLYMER, and ACRYLATES/DIMETHICONE COPOLYMER
What is Acrylates/Dimethicone Copolymer used for?
Acrylates are derived from acrylic acid and are commonly found in cosmetic nail preparations. Ethyl acrylate acts as an adhesive to apply artificial nails and eyelashes. Ethyl methacrylate and methyl methacrylate allow sculptured artificial nails to mold and adhere to the natural nail plate.

Reproductive effects were not observed in a study in which rats were dosed orally with 4500- or 90,000-Da molecular weight Sodium Polyacrylate. Oral Acrylates Copolymer Two studies were conducted in which an Acrylates Copolymer (as a fully polymerized copolymer of methyl methacrylate and ethyl acrylate) dispersion was sprayed onto powdered diet at a ratio of 1:10, and the coated diet was mixed with basal diet for testing.15 In the first study, groups of 20 mated female Wistar rats were fed 0, 500, or 2000 mg dry copolymer/ kg bw/day on days 6 through 15 of gestation, and the gravid rats were killed on day 19 of gestation. In the second study, groups of 10 mated female New Zealand White rabbits were given the same dosages on days 6 to 18 of gestation, and killed on day 29 of gestation. There were no signs of maternal toxicity in rats or rabbits, and there were no reproductive or developmental effects observed for either species. The NOAELs for dams and fetuses were 2000 mg/kg bw/day in both rats and rabbits.
General safety info about Acrylates/Dimethicone Copolymer from CIR
The Cosmetic Ingredient Review (CIR) Expert Panel assessed the safety of 126 acrylates copolymers; 56 of these ingredients were previously reviewed by the Panel, and 70 are reviewed herein for the first time. Many of these ingredients are reported to have several functions in cosmetics, with the function of film former being the most commonly reported cosmetic function for members of this family; many of the ingredients also may function in cosmetics as viscosity increasing agents. The Panel reviewed relevant new data, including frequency and concentration of use, and considered the data from previous CIR reports. The Panel concluded the 126 acrylates copolymers named in this report are safe in cosmetics in the present practices of use and concentration described in the safety assessment when formulated to be non-irritating
