The invention provides an oil-in-water emulsified cosmetic containing (a) an aqueous medium, (b) two or more higher fatty acids of 12 to 24 carbon atoms and alkali metal salts thereof, (c) at least one compound selected from the group consisting of monoalkyl glyceryl ethers having an alkyl group of 12 to 24 carbon atoms and monoalkenyl glyceryl ethers having an alkenyl group of 12 to 24 carbon atoms, (d) a thickener comprising (d-1) a polysaccharide derived from a microorganism and (d-2) a (meth)acrylic-based polymer selected from the group consisting of a poly(meth)acrylic acid salt and a polymer including at least one selected from the group consisting of a (meth)acrylic acid ester, a (meth)acryloylalkyltaurine and a salt thereof as a structural unit, and (e) a nonionic surfactant.

A process for decolorizing keratinous material which has been colored by the application of at least one pigment is disclosed. The process comprises applying to a dyed keratin material a decolorizing agent comprising at least one amphoteric and/or zwitterionic surfactant and a pH of from about 1.0 to about 4.3. The process further comprises rinsing the decolorizing agent from the keratin material after a contact time. A method for dyeing and later decolorizing human hair is also disclosed, and comprises applying a colorant to the hair to give a dyed hair, the colorant comprising at least one amino-functionalized silicone polymer and at least one pigment; applying to the dyed hair the decolorizing agent to give a decolorized hair; and rinsing the decolorizing agent from the decolorized hair. A multi-component packaging unit comprising a first container comprising the colorant and a second container comprising the decolorizing agent is also disclosed.

Methods for the use of prodrugs of itaconic acid and 1- and 4-methyl itaconic acid for inducing hair growth and treating an inflammatory, or immune activation (adaptive or innate), skin condition or other condition associated with hair loss are disclosed.

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.

A method for extracting a ceramide-containing material or ceramide from whole apples and/or apple juice extraction residue. Furthermore, to ensure utility as a food, especially a functional food, or a raw material for a cosmetic or medicine, that includes the ceramide-containing material. [Solution] In the present invention, an adsorbent is added to an ethanol treatment solution of whole apples and/or apple juice extraction residue, the mixture is stirred and subjected to solid-liquid separation, and solid material precipitated from the solution is separated, after which water is added to the resultant concentrate and the temperature thereof is maintained, whereby the resultant settled component is recovered and dried to obtain a ceramide-containing material or ceramide. Using the ceramide obtained from whole apples and/or apple juice extraction residue, there are formed a composition for promoting production of hyaluronic acid and/or type II collagen, and a composition for promoting improvement of memory impairment and/or enhancement of the level of phosphorylation of extracellular signal-related kinases (ERK1/2).
