The invention relates to a process for preparing surfactant solutions with N-acyl amino acids or their salts and to surfactant solutions with N-acyl amino acids or their salts obtained by the inventive process. The invention relates further to cosmetic or detergent cleaning compositions comprising solutions with N-acyl amino acids or their salts obtained by the process.

A composition for preventing hair loss and promoting hair growth includes: 100 parts by weight of an aqueous colloid solution containing nonionic copper nanoparticles having an average particle diameter (D50) of about 2 nm to about 10 nm; about 1 part by weight to about 10 parts by weight of glycerin; and about 1 part by weight to about 10 parts by weight of a co-solvent, wherein the nonionic copper nanoparticles are present in a concentration of about 2,000 ppm to about 3,000 ppm. The composition has the advantages of not only preventing hair loss but also promoting hair growth.

This disclosure relates to hair styling compositions and processes, and more particularly to compositions for disentangling or crosslinking hair that are useful in hair styling processes.

The invention relates to a cosmetic process for treating keratin fibers, preferably the hair, comprising at least the steps consisting in: a) applying to said keratin fibers a composition containing at least one substance chosen from fatty substances, non-silicone polymers and surfactants, b) applying a mechanical tension to said keratin fibers, and c) exposing said keratin fibers under mechanical tension to microwaves, at a pressure ranging from 50 000 to 250 000 Pa, in the presence of at least one solvent in vapor form on contact with the keratin fibers and without there being complete drying of the keratin fibers throughout the entire exposure to the microwaves, the solvent(s) in vapor form being entirely generated by evaporating at least one compound present, before emission of the microwaves, on contact with the keratin fibers, step a) taking place prior to step c).

We report a method of manufacturing solvent-free skin care products by substituting volatile organic compounds for polysorbate surfactants. A minimum effective concentration of food-grade polysorbate surfactants resulted in a fragrance composition that naturally separates layers following homogenization with gentle mixing.

A customized skin care composition. The skin care composition includes a base composition comprising one of an aqueous alcohol composition or an aqueous emulsion. The skin care composition further includes at least two booster compositions selected from the group consisting of a first grade exfoliating agent; a second grade exfoliating agent, the second grade exfoliating agent providing greater exfoliating than the first grade exfoliating agent; a first grade whitening agent; a second grade whitening agent, the second grade whitening agent providing greater whitening than the first grade whitening agent; a first grade anti-aging agent; and a second grade anti-aging agent, the second grade anti-aging agent providing greater anti-aging effects than the first grade anti-aging agent. The base composition and the at least two booster compositions have been mixed to form a composition that is stable and has efficacious concentrations of active ingredients corresponding to skin conditions of a consumer.

A method of treating a skin condition resulting from exposure to pollution or free radicals is disclosed. The method can include topically applying to skin having the skin condition a composition comprising an effective amount of an extract of Diospyros mespiliformis leaf to reduce oxidative damage in the skin having the skin condition.

Methods of making personal care compositions, such as dentifrices, involving the addition of rheology modifiers at a later stage in the personal care composition formation process.

A customized skin care composition. The skin care composition includes a base composition comprising one of an aqueous alcohol composition or an aqueous emulsion.

The base composition and the at least two booster compositions have been mixed to form a composition that is stable and has efficacious concentrations of active ingredients corresponding to skin conditions of a consumer.

This invention relates to xanthohumol-based compositions, yielded in a hot-melt extrusion process (HME) using one or more water-soluble nutritionally and/or cosmetically acceptable thermoplastic polymers, such as selected from hydroxypropylmethyl-cellulose (HPMC), a vinylpyrrolidone-vinyl acetate copolymer, and combinations thereof. The present invention also relates to topical and oral formulations comprising such extruded xanthohumol-based compositions, as well as the use of one or more water-soluble nutritionally and/or cosmetically acceptable thermoplastic polymers in a hot-melt extrusion process of xanthohumol.
