The invention relates to a composition in the form of a nanoemulsion or microemulsion, comprising: —a first fatty acid ester of polyglycerol which is chosen from a fatty acid ester of polyglycerol formed from at least one acid comprising an alkyl or alkenyl chain containing from 12 to 20 carbon atoms and from 3 to 6 glycerol units; —a second fatty acid ester of (poly)glycerol (c) which is chosen from a fatty acid ester of (poly)glycerol formed from at least one acid comprising an alkyl or alkenyl chain containing from 6 to 18 carbon atoms and from 1 to 3 glycerol units; —at least one organopolysiloxane elastomer; —at least two acrylic acid-based polymers that are different from one another; —at least one amphiphilic polymer comprising at least one 2-acrylamidomethylpropanesulfonic acid (AMPS) unit; —at least one oil; —water. The invention also relates to a cosmetic treatment process for keratin materials such as the skin, by application of such a composition.

The present invention provides a method and kit for the treatment of surfaces, such as the skin surface of a user, to impart hydrophobic characteristics upon the surface. The treatment of surfaces to impart hydrophobicity protects equipment, personnel, and animals from the effects of aqueous solutions such as water, toxic slurries, concrete, acids and bases.

A topical skin care composition including an effective amount of palmitoyl tetrapeptide 7, retinol, and a base that includes botanical oils is disclosed. The botanical oils include sesame oil, Helianthus annuus seed oil, jojoba oil, and Macadamia ternifolia nut oil. The topical skin care composition is anhydrous.

Methods and compositions for preventing or reducing hair frizz. The compositions are preferably oil-in-water or water-in-oil emulsions comprise at least one polysiloxane fluid component selected from an amodimethicone and a polysiloxane component comprising a plurality of hindered amine side chains. The compositions also comprise a silicone-compatible, volatile or non-volatile liquid carrier component, preferably comprising a component selected from a low molecular weight, volatile siloxy component; a hydrocarbon; and an alcohol. The compositions are preferably combing cremes, sprays or mousses, and are suitable for use a “leave-in” hair care product, or as a touch-up hair care product suitable for use during the day.

Cosmetic compositions, systems and methods for conferring responsive durable shaping of keratinous fibers employ at least one shape memory polymer that includes a three-armed branched polyethylene glycol (PEG) based polymer that is functionalized with one or more metal-coordination active groups. The shape memory polymer forms a crosslinked network coating on a substrate, for example a substrate selected from keratinous substrates, for example, hair. Hair coated with the shape memory polymer and treated with an oxidizing agent can be shaped, locked into shape, and reprogrammed by modulation of pH. The coated hair retains durable shaping properties through at least one shampoo treatment. The cosmetic compositions, systems and methods provide durable and reprogrammable durable shaping of the keratinous substrate, for example for styling hair.

A hair care formulation is provided, comprising: a dermatologically acceptable vehicle; a dermatologically acceptable oil; and a deposition aid polymer, wherein the deposition aid polymer is a dextran polymer functionalized with an amine group; wherein the dextran polymer has a weight average molecular weight of 100,000 to 650,000 Daltons; and wherein the deposition aid polymer enhances deposition of the dermatologically acceptable oil from the hair care formulation onto mammalian hair.

The purpose of the present invention is to provide an oil-in-oil cosmetic composition which is excellent in terms of transfer resistance after application, while having gloss, and which exhibits good spreadability when applied and enables the achievement of matte finish texture, while being prevented from the occurrence of a crack or the like and having excellent appearance stability. The present invention relates to an oil-in-oil cosmetic composition which is characterized by containing (a) from 5 to 80% by mass of a nonvolatile hydrocarbon oil and/or a nonvolatile ester oil, (b) from 1 to 70% by mass of a nonvolatile silicone oil and (c) from 3 to 13% by mass of a powder that has an average particle diameter of from 1 to 10 μm, and which is also characterized in that the nonvolatile hydrocarbon oil and/or the nonvolatile ester oil (a) and the nonvolatile silicone oil (b) are separated from each other when mixed at 25° C. It is preferable that the blending ratios (mass ratios) of the nonvolatile hydrocarbon oil and/or the nonvolatile ester oil (a) and the nonvolatile silicone oil (b) are set so that the value of (a)/((a)+(b)) is from 0.4 to 0.8.

A pigment suspension is disclosed. The pigment suspension comprises: (a) at least one coloring compound selected from the group of pigments; and (b) a hydroxycarboxylic acid ester. A cosmetic agent is also disclosed. The cosmetic agent comprises the pigment suspension, and one or more organic C.sub.1-C.sub.6 alkoxysilanes and/or condensation products thereof. A multi-component packaging unit (kit-of-parts) for dyeing keratinous material is also disclosed, and comprises separately packaged first and second containers. The first container comprises an agent (a′), which comprises one or more organic C.sub.1-C.sub.6-alkoxysilanes and/or condensation products thereof. The second container comprises an agent (a″), which comprises the pigment suspension.

A pigment suspension is provided. In one example, the pigment suspension includes a) at least one colorant compound selected from the group of pigments, b) at least one C.sub.1-C.sub.10 alcohol, c) at least one diol, d) at least one thickening agent, and e) water. A method for dyeing keratinous material and a multi-component packaging unit (kit-of-parts) for dyeing keratinous material including a pigment suspension are also provided.

The subject of the present disclosure is a process for dyeing keratinous material, in particular human hair. The process includes applying a first composition (A) to the keratinous material. The first composition includes (A1) one or more organic C.sub.1-C.sub.6 alkoxysilanes and/or condensation products thereof, and (A2) at least one colorant compound selected from the group of pigments and direct dyes. A second composition (B) is applied to the keratinous material. The second composition (B) includes (B1) Tannic acid.
