An object of the present invention is to provide a phycocyanin pigment composition insoluble in water and provide food, cosmetics, a coating material or a printing marker for pharmaceuticals or agricultural chemicals, a stationery product, a writing tool, a printing ink, an inkjet ink, a metal ink, a paint, a plastic coloring agent, a color toner, a fluorescent labeling agent, a fluorescent probe, or a chemical sensor, each containing the pigment composition. It was found that the phycocyanin pigment composition containing phycocyanin and a metal or a metal compound was insoluble in water, and thus the present invention was accomplished.

A composition comprising lipid and surfactant, characterised in that the surfactant has an HLB number of less than 20 and in that the lipid and surfactant are in the form of macromolecular assemblies of less than 10 nm in diameter.

A rinse off hair treatment composition comprising; a. a pressure sensitive adhesive emulsion comprising one or more pressure sensitive polymer, wherein the pressure sensitive polymer is not silicone pressure sensitive polymer, and b. at least one material selected from the group consisting of i) a hair conditioning agent; ii) a hair cleansing agent, and, c. a deposition aid.

Provided are skin care compositions that are useful as SPF and UV absorption boosters in formulations containing inorganic metal oxides. The compositions comprise (a) 0.1 to 20 weight % inorganic metal oxide particles, based on the weight of the composition, (b) 0.1 to 15 weight % copolymer particles dispersed in an aqueous medium, wherein the copolymer particles comprise polymerized units derived from (i) 0.1 to 20 weight % of phosphorus acid monomers, and (ii) 80 to 99.9 weight % of comonomers, and (c) a dermatologically acceptable carrier. Also provided are methods of protecting skin from UVA and UVB damage comprising topically administering such compositions to the skin, and methods of boosting the SPF or UV absorption of a sunscreen composition containing inorganic metal oxide particles comprising including such copolymer particles in the composition.

A solid particle ranging from 0.001 to 200 microns in diameter coated with Indium Tin Oxide (“ITO”) and a topical composition containing same as well as a method for protecting skin against IR radiation.

The present invention relates to hydrogel particles coated with lipid, which are made from dispersing hydrogel particles in an organic solvent in which lipids are dissolved, and to a method for manufacturing same. Unlike the existing method for manufacturing hydrogel core vesicles, the present invention can effectively manufacture same by using an emulsification method, without involving the steps of chemical treatment of the surface of hydrogels or dilution, thereby facilitating mass production and preventing the decrease of drug encapsulation efficiency. The present method could be widely used for research on delivery carriers of oil/water-soluble active material or cell structure reproduction and more particularly, a keratinocyte mimetic of the present invention containing natural moisturizing factors can contain a large quantity of bound water for a long time, thereby exhibiting superior capability to retain moisture and moisturize, and providing a composition for an ingredient in cosmetics for moisturizing.

The present disclosure relates to a composition having cellulose acetate particles having a sphericity from 0.7 to 1.0 and a surface smoothness from 80% to 100% or less, and a method of manufacturing and use thereof.

Disclosed are skin care compositions containing refractive polymeric particles. The composition improves the appearance of skin but reducing gloss without a noticeable presence on the skin surface.

The present invention relates to a composition comprising particles of a polymer that is surface-stabilized with a stabilizer, the polymer of the particles being a C.sub.1-C.sub.4 alkyl (meth)acrylate polymer; the stabilizer being an isobornyl (meth)acrylate polymer chosen from isobornyl (meth)acrylate homopolymer and statistical copolymers of isobornyl (meth)acrylate and of C.sub.1-C.sub.4 alkyl (meth)acrylate present in an isobornyl (meth)acrylate/C.sub.1-C.sub.4 alkyl (meth)acrylate weight ratio of greater than 4, at least one hydrocarbon-based oil and at least one mineral thickener chosen from optionally modified clays and optionally modified silicas, or mixtures thereof. The invention also relates to a process for making up and/or caring for keratin materials, in which said composition is applied.

The present invention relates to an emulsion not containing any emulsifying surfactant, in particular to an oil-in-water emulsion not containing any emulsifying surfactant, characterized in that it comprises, especially in a physiologically acceptable medium, at least composite particles comprising a core comprising at least organic or inorganic particles A; said core being covered at the surface, continuously or discontinuously, with an envelope comprising at least organic or inorganic particles B; said particles A and B having different polarities.

The present invention also relates to the use of the composite particles as defined previously as emulsion stabilizer, in particular as stabilizer for an emulsion not containing any emulsifying surfactant, and more particularly as stabilizer for an oil-in-water emulsion not containing any emulsifying surfactant.

The present invention also relates to a cosmetic process for treating a keratin material, which consists in applying to the keratin material an emulsion as defined previously.
