Suggested is an active mixture comprising

(a) 1,2-hexanediol and
(b) 1,2-octanediol.

The present invention provides a bicontinuous microemulsion composition, including: (A) polyglycerin group-containing organo(poly)siloxane shown by the general formula (1):

##STR00001##

wherein R.sup.1 represents an alkyl group or a phenyl group, R.sup.2 represents a group having a polyglycerin structure shown by the formula (2) or the formula (3), R.sup.3 represents R.sup.1 or R.sup.2, a is 0 to 6, b is 0 to 4, a+b is 0 to 10, and at least one of R.sup.3 is R.sup.2 when b is 0:

##STR00002##

wherein R.sup.4 represents an alkylene group or an aralkylene group, c is 0 to 10, and d is 2 to 6; (B) silicone oil having a viscosity of 20 mm.sup.2/s or less at 25? C., volatile hydrocarbon oil, or ester oil; and (C) water. This provide a transparent bicontinuous microemulsion composition in which anionic or cationic surfactant, and water-soluble monovalent or polyvalent alcohol are unnecessary; and a cosmetic with excellent pleasantness of use.

The present invention provides an emulsified cosmetic, including: an anionic acryl silicone copolymer (A) having an acryl chain as the main chain, the copolymer including, as monomer units, (I) 1 to 30% by mass of a polymerizable hydrophilic monomer having carboxylic acid, phosphoric acid, or sulfonic acid neutralized with a base, and (II) 10% by mass or more of a silicone macromonomer represented by the following general formula (1), or a silicone dendron group-containing polymerizable monomer; an oil material (B); and water (C). Accordingly, the present invention provides an emulsified cosmetic having excellent emulsification stability and non-stickiness.

The present invention provides a makeup cosmetic and method of manufacturing the same attained by a water-in-oil emulsion cosmetic supplemented with an oil-in-water emulsion as a water phase in which fine (nano-sized) oil droplets containing a solid oil and having a specified predetermined particle size are dispersed. Specifically, the present invention provides a makeup cosmetic comprising an oil-in-water-in-oil (O/W/O) composite emulsion in which an oil-in-water (O/W) emulsion is dispersed in an external oil phase, wherein the oil-in-water (O/W) emulsion comprises oil droplets having a number-average particle size of 200 nm or smaller and containing a solidified oil.

It relates to a multi-walled water-in-oil-in-water nanoencapsulate and to a hybrid water-in-oil-in-water polyurethane/polyurea liposome comprising internal water droplets which are dispersed within larger oil droplets which are themselves dispersed in an external aqueous continuous phase or which form part of structures resembling liposomes; the polymeric walls are obtainable in a water-in-oil and in an oil-in-water emulsification process by phase inversion, respectively. It also relates to its preparation process, and compositions comprising them.

The present invention relates to a cosmetic composition of a multiple emulsion formulation having a lamellar liquid crystal structure, and a method for preparing the same. More particularly, the cosmetic composition is prepared using different single emulsification type emulsions, i.e. a W/O type emulsion and an O/W type emulsion which has a lamellar liquid crystal structure, or using a mixture having constituent ingredients thereof. Thus, the present invention has effects of stably maintaining effective ingredients of the cosmetic composition, and enhancing the feeling of use.

A method for treatment and/or care of the skin includes administering a composition to the skin of an individual. The composition includes a combination of a compound (I) of formula (A) or (B);

##STR00001##

wherein R.sup.1 and R.sup.2 are identical or different and are independently selected from the group consisting of OH, CH.sub.3, CF.sub.3CH.sub.2O and CH.sub.3O; and an anionic polymer (II) which is a copolymer of acrylic acid or methacrylic acid and 2-methacrylamido-2-propane sulfonic acid or 2-acrylamido-2-propane sulfonic acid. The method is suited to the treatment of the adverse effects of air pollution on the skin, mucous membranes, hair and/or nails.

A cosmetic composition containing a multiple emulsion formulation is provided. The multiple emulsion formulation contains droplets including an inner phase and an outer phase and an outermost phase, and an outermost phase. The inner phase may be an oil phase and the outer phase may be an aqueous phase, and the outermost phase includes silicon-based oil. The cosmetic composition may provide excellent formulation stability due to the distribution of the droplets very close to the outermost phase.

A cosmetic preparation containing a crosslinkable silicone rubber emulsion comprising (A) 100 parts by weight of a straight chain or branched organopolysiloxane containing at least two hydroxyl groups bonded to the silicon atom per molecule prepared by ring-opening polymerization of a cyclic organosiloxane in the presence of an alkoxysilane or its partial hydrolytic condensate or an ,-dihydroxy or dialkoxy siloxane oligomer by using a catalyst selected from citric, lactic, and ascorbic acids and an anionic surfactant emulsifier; and (B) 0.5 to 20 parts by weight of a reaction product of an amino group-containing organoxysilane and an acid anhydride.

Disclosed is a water-in-silicone emulsion comprising a discontinuous water phase, a continuous silicone phase, and a silicone polyglucoside containing emulsifier, wherein the discontinuous water phase does not include a salt.
