A composition for external use containing a tranexamate as an active ingredient with suppressed sticky or oily feeling but having a fresh feel of use, and a method for producing the same. A tranexamate salt can be dispersed stably in an aqueous medium by (a) dissolving the tranexamate salt and an amphiphilic polymer in water, a water-soluble organic solvent or a mixture thereof; and (b) adding a mixed solution obtained in the step (a) to an aqueous medium, and thus keeping the tranexamate salt in molecular assembly particles formed of the amphiphilic polymer.

The present invention relates to a composition, preferably a cosmetic composition, comprising: (a) at least one oil; (b) at least one polyglyceryl fatty acid ester, preferably with a polyglyceryl moiety derived from 2 to 6 glycerins; (c) at least one compound selected from the group consisting of resorcinol and resorcinol derivatives; and (d) water. The composition according to the present invention can be in the form of a nano- or micro-emulsion, or can have a lamellar structure or a lamellar phase, with better transparency and stability.

The invention provides for a topical o/w emulsion having moisturizing, and protecting, repairing or restoring the skin lipid barrier of the lips of a mammal, and is a topical oil-in-water emulsion composition comprising: (a) a discontinuous oil phase; (b) a continuous aqueous phase comprising water; (c) a thickening agent; (d) at least one lamellar membrane structure comprising (i) an alkyl amphiphilic component, (ii) an ester of a branched fatty acid and a branched fatty alcohol, (iii) a fatty acid, (iv) a fatty alcohol, and optionally (v) a phospholipid; and wherein in use the composition has a water vapor transmission rate of less than 65 g.Math.m.sup.−2.Math.hr.sup.−1 measured in vitro.

Personal care topical compositions at skin-tolerant pH with cystine which is solubilized or has small crystal size below 20 microns. A process of making the composition is also described.

The subject matter of the present invention is a cosmetic or pharmaceutical composition for controlled moisturizing and release of active molecule(s), comprising at least one emulsifier having an enzyme cleavable bound, at least one emollient, at least one polar solvent, and water, forming together a macroscopically homogenous liquid crystals emulsion. In some embodiments of the invention, the composition also includes at least one ingredient having a cosmetic or pharmaceutical activity.

The present invention relates to a cosmetic composition for coating keratin fibres, comprising: —an aqueous phase, —a surfactant system present at a total content of greater than or equal to 15% by weight relative to the total weight of the composition, said surfactant system comprising: i) at least one non-ionic surfactant with an HLB value at 25° C. of less than 8, and ii) at least one anionic surfactant with an HLB value at 25° C. of greater than or equal to 8, chosen from acyl glutamic acids and salts thereof, together forming a lamellar phase Lβ, and—at least one aqueous dispersion of particles of at least one film-forming polymer. The present invention also relates to a process for coating keratin fibres.

The composition of external application to the skin according to the present invention may specifically control the relative amount between long-chain amides and sterols and the relative amount between lipid components and an emulsifier in the emulsion having a multi-layered lamella structure, the emulsion comprising a relatively larger content of dermatologically useful hydrophobic material in a formulation. Thus, the formulation having significantly high stability and excellent characteristics can be obtained in spite of the high content in the lipid components and the emulsifier.
