Ethyl Polysilsesquioxane is a resinous material composed of a mixture of three-dimensional siloxane polymers and oligomers with cage structures. For the oligomers, each silicon atom in the polysilsesquioxane is connected via oxygen atoms to three other silicon atoms and can be represented by the empirical formulation RSiO3/2, where R represents the ethyl group. For the larger polymeric polysilsesquioxanes, some of the silicon atoms are not connected to other silicon atoms and instead have a sila Science: Functions: Nail Conditioning Safety Ratings: CIR: Safe as used

Functions
Nail Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Film Forming
Creates a physical seal on skin to lock moisture in and keep irritants out. The "slugging" ingredient — barrier protection.
Moisturizing
Locks in moisture to keep skin soft and supple throughout the day
Strengthens Barrier
Strengthens nails
Traditional Use
A synthetic silicone polymer developed in the late 20th century for cosmetics. Used as a film-former and texture enhancer that provides a silky feel and improved water resistance in masques and primers.
