Lonza Ltd.
Enzyme delivery systems, application in water based products
Disclosed are aqueous enzyme delivery systems as well as aqueous cosmetics and personal care products which comprise at least one stabile enzyme and a polyglycerol containing at least 15 carbons. Also disclosed are stabile non-aqueous enzyme delivery systems that are dispersions of at least one enzyme in a non-aqueous viscous liquid. Methods are provided for the treatment of human skin in recreational water applications by means of enzymes.

Kao Corp.
Resin particles comprising a (meth)acrylate copolymer and a surfactant having a sulfonic-acid or sulfonate group
The invention relates to cross-linked (meth)acrylate-based resin particles having an average particle diameter of 1 to 10 μm. Among the particles’ monomer components are a monomer having a carboxyl group and at least one monomer selected from an acrylate and a methacrylate copolymerized therein. The particles have a surface coated with a surfactant having a sulfonic acid group or a sulfonate group. A process is described for producing these particles, which confer not only extendability and smoothness but also dry feeling on cosmetics, and in themselves have smoothness and dry feeling.

The Procter & Gamble Company
Emulsion compositions
The present invention relates to particle stabilizing compositions suitable for use in pharmaceuticals, oral care products, antiperspirants, deodorants, personal cleansing products, skin care products and hair care products, among others. The emulsion comprises 1–99% by weight internal phase and 1–99% by weight external phase. A charged species is present in the emulsion. Charged insoluble solid particles are dispersed in the emulsion wherein the charged species possesses a charge that is opposed to that of the charged insoluble solid particles and wherein essentially all of the charged species and charged insoluble solid particles accumulate at the interface of the emulsion. Brownian motion is not exhibited by the charged insoluble solid particles.

Cosmetic compositions using polyether siloxane copolymer network compositions
In a preferred embodiment the reaction product of this invention is a polyether siloxane copolymer network. In another preferred embodiment embodiment the reaction product of the present invention is a polyether siloxane copolymer network swollen with a volatile low molecular weight silicon-containing compound. These compositions are useful for a variety of personal care compositions, especially ones designed to deliver multiple performance products based on mixtures of several components, with each having performance characteristics important to or desirable in the final formulation.

Avon Products Inc.
Use of Alisma orientale in cosmetics and compositions thereof
Disclosed are compositions and methods for improving the appearance of skin, particularly, treating, preventing, ameliorating, reducing and/or eliminating excess accumulation or production of subcutaneous fat, such as cellulite, by topically applying compositions comprising Alisma orientale constituents, or extracts therefrom. The compositions are also intended to address conditions related to excess accumulation, production, or excretion of sebum, such as acne, an oily complexion, oily hair or scalp, as well as undesirable body odor

Snow Brand Milk Products Co., Ltd.
Skin-beautifying agent
Disclosed is a skin-beautifying agent comprising a milk-derived phospholipid as an active ingredient in a food, beverage or feed. Preferably, the milk-derived phospholipid is a composition prepared from milk or a milk material, contains a lipid in an amount of 40–70 wt% relative to the total amount of all solid materials and also contains the milk-derived phospholipid in an amount of 30 wt% or more relative to the total amount of all solid materials. WO/2008/096888 Fujifilm Corp. Powder composition, method for producing the same, and food composition, cosmetic composition and pharmaceutical composition containing the same A powder composition of a functional oil material is obtained by drying an emulsion composition comprising at least one functional oil component and at least one water-soluble encapsulating agent such that (i) the encapsulating agent is selected from saccharides containing at least two sugar units including a fructose unit or (ii) the encapsulating agent is selected from saccharides containing at least one galactose unit and one fructose unit. Illustrations show the powder used in food, cosmetic and pharmaceutical compositions.

WO/2008/102998
Biospectrum Inc.
Compositions for improving skin conditions comprising carvacrol as an active ingredient
Carvacrol used as an active ingredient has lower cytotoxicity than retinol used as an antiwrinkle agent. It also inhibits collagenase activity and promotes collagen biosynthesis at a molecular level. Carvacrol is an antioxidant. It also promotes skin growth and helps prevent hair loss. Compositions of this invention can be applied to cosmetic, pharmaceutical and food compositions having no cytotoxicities and side effects.

WO/2008/102997
Biospectrum Inc.
Compositions for improving skin conditions comprising matrine or its oxidized derivatives
Matrine and oxymatrine have lower cytotoxicity than retinol when used as an antiwrinkle agent. They also inhibit collagenase activity and promote collagen biosynthesis at a molecular level. They also inhibit melanin production by inhibiting intracellular tyrosinase activity. Furthermore, they have the excellent antiobesity and antioxidation effects. Compositions of this invention can be applied to cosmetic, pharmaceutical and food compositions having no cytotoxicities and side effects.
