Ascorbic acid glucoside, peptides in liquid cosmetics: Kosei Co., Ltd., also discloses liquid cosmetic compositions containing ascorbic acid glucoside and basic peptides.14 The liquid cosmetic composition disclosed is characterized by containing L-ascorbic acid glucoside and a basic peptide, e.g., N-beta-alanyl-L-histidine, wherein the use of the basic peptide improves storage stability of the ascorbyl glucoside without causing discoloration. An example is shown in Formula 10.
Cosmetic/therapeutic compositions, flexible solid films: Biofarmitalia S.p.A. discloses solid cosmetic and therapeutic compositions and flexible solid films comprising hyaluronic acid. These compositions are applicable to human skin and gel upon contact with water.15 The compositions prepared as flexible solid films can be used for cosmetic and/or therapeutic purposes. They may contain hyaluronic acid, a fine, inert powder, and water as essential components. Thus, a solid film with a hydrating and filling effect on cutaneous microprotuberances comprised: water as a solvent at 80.2 kg; hyaluronic acid as a filmogen at 9.8 kg; and lauroyl lysine, an inert powder, at 10 kg.
Silicone elastomers in cosmetics: L’Oréal discloses an anhydrous cosmetic composition comprising nonspherical silicone elastomers and a silicone elastomer encapsulated in silicone.16 The compounds can be used for makeup and hair compositions. An example is shown in Formula 11.
Hydrofluoro ethers, polyhydric alcohols and emulsifiers: Shiseido Co., Ltd., discloses cosmetic compositions containing hydrofluoro ethers, polyhydric alcohols and emulsifiers.17 The disclosed invention relates to a composition that provides a sensory cue of feeling cool then warm on the skin, without leaving a sticky residue. The described composition contains: a) a hydrofluoro ether having a viscosity at 25°C < 5 mPa•s; b) a polyhydric alcohol; and c) an emulsifier; and wherein the composition contains little or no water. An example is shown in Formula 12.
Kosei Co., Ltd., also discloses liquid o/w cosmetic emulsion compositions.18 These liquid o/w cosmetic emulsions contain higher amounts of oil with low viscosity, and having good storage stability. One example composition disclosed contained 0.5–2.0% isostearic acid; 1–3% basic amino acid; 7–20% of an oily component; 0.2–1.5% glyceryl stearate; and 0.2–1.5% of a higher alcohol. The composition reportedly showed a viscosity at 25°C of < 500 mPa•s. An example is shown in Formula 13.
