Tuber enzymic hydrolyzates for cell proliferation: Kao Corp. discloses epidermal cell proliferation stimulators containing tuber enzymic hydrolyzates from Tuber mycelium; e.g., Tuber magnatum and/or Tuber melanosporum mycelium.6 The epidermal cell proliferation stimulator is suitable for use in antiaging, skin-lightening or wound-healing applications. For example, freeze-dried and crushed Tuber melanosporum (black truffle) mycelium was treated with Actinase E and Tunicase FN to obtain an enzymic hydrolyzate for studying its effect on epidermal cell proliferation in vitro.
Oligomers, powders for eyelashes and brows: Kosei Co., Ltd., discloses makeup for eyelashes and eyebrows comprising olefin oligomers and surface-treated powders.7 The disclosed makeup contains alpha-olefin oligomers, powders that are surface-treated with siloxy group-containing methacrylate copolymers, volatile solvents and, optionally, solid oils. An example of a mascara gel is shown in Formula 6.
Colored fibers, treated powders for eyelashes, brows: Kosei Co., Ltd., has diclosed cosmetics for eyelashes and eyebrows comprising colored fibers and surface-treated powders.8 The described cosmetics include colored fibers and powders that are surface-treated with siloxy group-containing methacrylate copolymers, in addition to membrane-forming ingredients and, optionally, solid oils. An example of a mascara cream is shown in Formula 7.
O/W emulsions for eyelashes: Kosei Co., Ltd., also discloses o/w emulsions for eyelashes containing water-soluble polymers and modified organopolysiloxane.9 This cosmetic composition provides a volumizing and lengthening effect and contains a stringing, water-soluble polymer and a solid or paste, long-chain alkyl-modified organopolysiloxane or long-chain alkoxy-modified organopolysiloxane having a melting point < 60°C. The composition may further contain a film-forming polymer emulsion and/or a wax. An example of a cream-type mascara composition is shown in Formula 8.
Monodisperse particles for keratin surfaces: L’Oréal discloses a cosmetic composition for keratinous surfaces comprising monodisperse particles in a liquid medium.10 The invention is designed for, but not limited to, application to keratinous materials, in particular the skin, lips, nails or eyelashes. The composition comprises: a physiologically acceptable liquid medium that is anhydrous and non-pulverulent, including an oily phase such as a polysiloxane; and monodisperse particles suitable for forming an ordered lattice of monodisperse particles on a substrate, onto which the composition is applied.
