Abstract:
PURPOSE: A cosmetic composition containing an amorphous poly(cycloolefin) is provided which offers a membrane forming property and a good maintenance for care and/or make-up cosmetic composition against the surface of face, body, lips mucous membrane, rail, eyelashes, eyebrow, hair, etc.. CONSTITUTION: The cosmetic composition is applied to keratin substances containing a liquid fatty acid, and contains the effective dose of amorphous poly(cycloolefin) or its mixture. The liquid fatty acid contains one more than oil that the formula includes one more than carbon-containing nucleus.
Abstract:
PURPOSE: A cosmetic composition is prepared from a mixture of hydrophilic materials in an aqueous phase and a mixture of lipophilic materials in an organic phase, to provide a uniform product. CONSTITUTION: The cosmetic composition comprises a medium containing a liquid organic phase and an aqueous emulsion phase as a physiologically acceptable medium thickened with associated polyurethane. The associated polyurethane content is more than 5 milligrams/square meter of the organic-in-water developed area and 2 to 20 wt.% based on the total weight of the composition. The associated polyurethane includes a sequence or craft polymer having at least two C6-C30 alkyl chains separated by a hydrophilic sequence. The composition has a viscosity of 1,000 to 10,000 cp (i.e., 1 to 10 Ps.s) measured with 100 s¬(-1) at 25°C. The physiologically acceptable medium is an organic-in-water emulsion. The liquid organic phase content is 0.1 to 30 wt.% based on the total weight of the composition.
Abstract:
PURPOSE: A composition containing a fiber and a copolymer comprising carboxylate groups and polydimethylsiloxane groups is provided which can especially constitute a care or make-up composition for keratin materials such as the skin, including the scalp, the lips of the face and integuments, for instance the eyelashes, the eyebrows, the nails and the hair. CONSTITUTION: The composition for topical application contains 0.1 to 50% by weight of a fiber and 0.01 to 20% by weight of one or more copolymers comprising carboxylate groups and polydimethylsiloxane groups and having a molecular weight of 5,000 to 200,000 in a physiologically acceptable medium, based on the total weight of the composition. The fiber has a length of 1 μm to 10mm, a cross section of 1nm to 100μ m and a yarn count of 0.15 to 30 denier.
Abstract:
PURPOSE: Prepared is an agent effective for restricting or preventing the migration of a composition for keratinous substance containing a liquid fat phase, having glossy appearance, resistant to drying with time and giving a composition free from uncomfortable feeling by including an olefin copolymer having a controlled medium crystallinity and soluble or dispersible in the above-mentioned liquid fat phase. CONSTITUTION: The active substance of the composition for keratinous substance contains at least one kind of copolymer selected from crystalline olefin copolymer having a crystallinity of 50% or less, preferably 5-40%, more preferably 10-35%, a melting point of preferably 150deg.C or lower, a weight-average molecular weight (Mw) of 30,000 and a polydispersity index Mw/Mn of less than 3.5, a bipolymer of ethylene or propylene and a 4-12C alpha-olefin and soluble or dispersible in a liquid fat phase (an arbitrary non-aqueous medium which is liquid at room temperature under atmospheric pressure, especially an oil or a solvent). The amount of the copolymer in the active substance is preferably 0.5-70%.
