Bioflavonoid Compositions and Their Use
The present invention relates to pharmaceutical compositions and their use in oral hygiene. More particularly, the compositions comprise one or more flavonoids, such as naringin and neohesperidine and polylysine and/or caprylic acid and/or a zinc salt. Such compositions may be in the form of, for example, a solution, gel, spray, chewing gum or paste suitable for use in the oral cavity. The composition may be used in reducing bacterial numbers on teeth, gums or other surfaces in the oral cavity.
Cosmetic composition comprising glycolic acid and methods of use
The present disclosure relates to stable cosmetic compositions that include high levels of free glycolic acid. The cosmetic compositions typically include: glycolic acid and/or a salt thereof; at least one non-silicone fatty compound; at least one emulsifier; at least one water-soluble solvent; at least one silicone; and water. The cosmetic compositions are in the form of an emulsion, in particular, a water-in-oil emulsion, and typically have a low pH of below 7. Also, the cosmetic compositions have high amount of free glycolic acid, for example, at least 6 wt. % of free glycolic acid, based on the total weight of the cosmetic composition. The cosmetic compositions are particularly useful for improving the appearance of skin. Accordingly, the instant disclosure relates to methods of treating skin, for example, improving the appearance of skin using the cosmetic compositions.

Poly (amino acid) rheology modifier compositions and methods of use
Rheology modifiers comprising cross-linked poly(amino acid) and methods of their use in aqueous compositions. The modifiers comprise cross-linked poly(amino acid) microparticles having a mean equivalent diameter when fully swollen in deionized water of up to 1000 μm, as measured by laser diffraction. In particular, the poly(amino acid) is D-, L- or D,L-Y-poly(glutamic acid). A method of preparing the modifier comprises cross-linking a poly(amino acid), drying the cross-linked poly(amino acid) and grinding the cross-linked poly(amino acid) to have the required diameter.

EXPANDED POLYMER POWDERS
The invention relates to small expanded polymer powder particles, and uses thereof. The expanded powder particles are formed by a non-melt process, resulting in individual expanded particles in the 5 to 100 micron range. The expanded powder particles are especially useful in cosmetic applications, as they provide a softer feel than a powder, and have a much higher surface area, making them highly absorbent for removing liquids and oils, as well as for use as excellent carriers and release agents for active ingredients.
