Abstract
Non-silicone-based compositions including hydrocarbons of widely different structures and origins are combined into single, stable, homogenous products with both aesthetic and volatility properties similar to a cyclopentasiloxane. The combinations are useful to cosmetic formulators as full or partial replacement products for cyclopentasiloxanes, or “volatile silicones.”
Claims13
A non-silicone-based composition consisting essentially of:
- about 35% of a first hydrocarbon component selected from a C12-C14 isoparaffin, about 55% of a second hydrocarbon component selected from a C13-C16 isoparaffin,
- and about 10% of at least one further component selected from the group consisting of a C13-15 mixed alkane and a cosmetically acceptable oil,
- wherein the composition approximates the volatility and aesthetics of cyclomethicone.
A non-silicone-based composition which approximates the volatility and aesthetics of cyclomethicone comprising a component consisting essentially of:
- about 35% of a first hydrocarbon component selected from a C12-C14 isoparaffin, about 55% of a second hydrocarbon component selected from a C13-C16 isoparaffin and about 10% of a further component selected from the group consisting of a C13-15 mixed alkane and a cosmetically acceptable oil,
- the non-silicone based composition further comprising a cosmetically or pharmaceutically acceptable carrier.
