20210401722 · 2021-12-30 · ·

Disclosed is a cosmetic composition that contains at least one polyhydroxyalkanoate (PHA) in the form of particles having an average diameter (d50) from 0.1 nm to 50 μm. The PHA may comprise between 0.1% w/w and 30% w/w of the total cosmetic composition, and some embodiments may utilize between 1% w/w and 8% w/w. The composition may include a silicone external phase or may be in the form of a loose or packed powder. Various PHAs may be utilized, although advantageously, the PHA may have a chain length 1 and 8 carbons. In some embodiments, the PHA may be selected to have an oil absorption of between 60 to 150 grams of a desired oil per 100 grams of PHA, where the desired oil may be, e.g., sebum. Further, the composition may optionally include one or more pigments. In use, the composition may be applied to a user's skin or hair.

COSMETIC COMPOSITION COMPRISING SPECIFIC HYPERBRANCHED COPOLYMERS AND OILS
20210393504 · 2021-12-23 ·

The present invention relates to cosmetic compositions which comprise a hyperbranched copolymer of the monomers dodecenyl succinic acid anhydride, diisopropanol amine and bis-dimethylaminopropyl amine having quaternary terminal groups and an oil with a polarity index of either in the range of 50-30 mN/m or in the range of 18-5 mN/m. The copolymer is used in a cosmetic composition comprising the at least one oil for reducing the material transfer to a contacted surface. Preferably the copolymer is polyquaternium-110.
