Polymer specific to Estée Lauder, patented US20160030328, by Estée Lauder (ELC Management) and Shin Etsu, claimed as a water-absorbing polymer obtained from (A) a phosphate-containing (meth)acrylic monomer and/or a salt thereof, (B) a monomer having one (meth)acrylic group within the molecule and/or a salt thereof other than component (A), and (C) an organopolysiloxane having a (meth)acrylic group at both ends and related compositions.
This polymer is claimed to provide a cosmetic composition which exerts a high thickening effect in aqueous solvents, eliminates poor spreading, moist and sticky feels, and is in paste form having thixotropy and giving a dry light feel. This polymer solves the following issue : create a film on skin that blurs skin defects such as lines, wrinkles, or minor skin imperfections. In addition to provide aesthetically pleasing thickening properties, when the same polymers provide other benefits such as optically improving the appearance of the skin surface this provides a further advantage.
Also patented by Estée Lauder (US9387161) as used to make compositions for reducing pore size, and moisturizing and/or blurring appearance of defects on keratin surfaces
