A first problem is to provide a novel technique for forming hyaluronan into particles. Further, a second problem is to provide a novel technique suitable for production of a composite particle containing an anionic polymer and a peptide. Means for solving the first problem is a composite particle containing an anionic polymer, and a cationic polymer (except for chitosan) having a degree of cationization of 0.2 or more. Means for solving the second problem is to mix an anionic polymer and a peptide in an aqueous solvent having a pH of 5 or less.

In accordance with a first aspect, the invention relates to microcapsules for use in a high demand area selected from detergents and cleaners, cosmetic products, adhesive systems, paints and dispersions, coating materials comprising a core material and a shell, wherein the shell consists of at least a first and a second layer whose chemical compositions differ, and wherein the shell has a biodegradability measured according to OECD 301 F of at least 40%. The invention further relates to a product comprising microcapsules, wherein the product is selected from the group consisting of an adhesive system; a cosmetic product; a pharmaceutical product; a coating material, in particular a coated paper; a heat storage coating, a self-healing coating or a corrosion coating; and a coating of functional packaging materials.

A transparent liquid composition is provided which has excellent handling properties when used in cosmetic production without causing increases in viscosity or precipitation of insoluble matter during storage, and which imparts hydrophobicity to damaged hair when added to a cosmetic, and is smooth, moist and soft so feels good during use; a cosmetic containing this transparent liquid composition is also provided. This transparent liquid composition is characterized by containing (A) a compound selected from a group consisting of peptides, amino acids and derivatives thereof, (B) fatty acid amidoamines, (C) gluconic acid and/or gluconolactones and (D) a polyhydric alcohol, wherein the mass ratio (C)/(B) of component (C) to component (B) is 0.5-2.0.

Disclosed herein are methods for efficiently isolating collagen form a collagen source. The methods are inexpensive and do not require the use of proteolytic enzymes, decolorizing agents, antibacterial and antifungal agents, and the like. Further, the collagen produced by the methods described herein is substantially free of odor and discoloration. Still further, the collagen produced by the methods described herein is suitable to be used in cosmetics, food products, and pharmaceuticals or nutritional supplements.

The present invention provides improved anti-aging skin cream formulations. The anti-aging cream formulations contain tretinoin, niacinamide, hyaluronic acid, collagen, red wine extract, α-tocopheryl acetate, Butyrospermum parkii (shea butter) extract, and suspendisse cream. The present invention also provides kits containing the formulations, methods of making the formulations as well as methods of using these formulations to visibly reduce signs of aging.
