Cosmetic compositions comprising silicone based materials cured via a condensation cure chemistry are disclosed. In particular, the present disclosure relates to cosmetic compositions comprising a silicone based gel cured via a condensation cure chemistry; and at least one cosmetic ingredient, optionally in a cosmetically acceptable medium. Preparation methods and uses of the cosmetic compositions are also disclosed.

Cosmetic composition comprising silicone materials

Aminofunctional silicone compositions are disclosed comprising: an organopolysiloxane having an average formula of (CH)SiO[(CH)SiO][(CH)RSiO]Si(CH)with less than 1 weight % of nitrogen in its formula, where Ris an aminofunctional group, x is &#x2265;100, y is &#x2265;1 with the proviso the sum of x+y is from 250 to 350; wherein the viscosity of the silicone composition ranges from 1000 to 2500 cP at 25&#xb0; C. and is measured by a Brookfield RV DV viscometer equipped with Pro CP 52 spindle at 20 RPM; and the aminofunctional silicone composition contains less than 0.1 weight % of D4 and less than 0.1 weight % D5 cyclic siloxanes.

Aminofunctional organosiloxanes

Aqueous silicone emulsions are disclosed comprising: A) an aminofunctional organopolysiloxane, B) a quaternary ammonium surfactant having a formula RRRRNX, where Ris an organofunctional group containing at least 10 carbon atoms, Ris Ror a hydrocarbyl containing 1 to 12 carbon atoms, Ris R, R, or an alcohol group containing 2 to 10 carbon atoms, Ris R, R, or R, Xis a halide, sulfate, sulfonate, methosulfate, or ethosulfate, C) a nonionic surfactant, where the aqueous silicone emulsion contains less than 0.2 weight % of D4 and D5 cyclic siloxanes.

Aminofunctional Silicone Emulsions

Aminofunctional silicone compositions are disclosed comprising: an organopolysiloxane having an average formula of (CH)SiO[(CH)SiO][(CH)RSiO]Si(CH)with less than 1 weight % of nitrogen in its formula, where Ris an aminofunctional group, x is &#x2267;100, y is &#x2267;1 with the proviso the sum of x+y is from 250 to 350; wherein the viscosity of the silicone composition ranges from 1000 to 2500 cP at 25&#xb0; C. and is measured by a Brookfield RV DV viscometer equipped with Pro CP 52 spindle at 20 RPM; and the aminofunctional silicone composition contains less than 0.1 weight % of D4 and less than 0.1 weight % D5 cyclic siloxanes.

A composition for controlled release of an active material such as a fragrance, sunscreen, vitamin or biocide in a product such as a hair shampoo, shower gel, another personal product such as an antiperspirant or deodorant, a household cleaning product such as a laundry detergent, hard surface cleaner or polishes, or a fabric softener, air freshener or tumble drier sheet, comprises a blend of the active material and a waxy cyclopolysiloxane. The cyclopolysiloxane is preferably substituted by hydrocarbon substituents having 12 or more carbon atoms and may also contain an aryl or aralkyl substituent.
