Disclosed is a composition comprising, in an aqueous phase: a) at least one ether of formula (I): R—O—R′ in which R and R′, which may be identical or different, denotes a linear or branched C.sub.6-C.sub.25 alkyl or alkenyl radical, R and R′ being chosen such that the ether is liquid at a temperature of less than or equal to 30° C.; b) at least one surfactant chosen from anionic surfactant, amphoteric or zwitterionic surfactant, or a mixture thereof; c) at least one cationic alkyldiallylamine or dialkyldiallylammonium cyclopolymer; and d) soybean oil.

Provided is a composition comprising, in an aqueous phase at least one anionic surfactant, at least one amphoteric and/or zwitterionic surfactant, at least one alkyl(poly)glycoside nonionic surfactant, at least on polymer chosen from cationic polymers of cationic cellulose, cationic alkyldiallylamine or dialkyldiallylammonium cyclopolymer, amphoteric polymers which comprising one or more units derived from a monomer of (meth)acrylate or (meth)acrylamide type, a monomer of (meth)acrylamidoalkyltrialkylammonium type, or a monomer of (meth)acrylic type, or a mixture thereof, and at least on fatty acid ester of glycerol and/or of polyglycerol.

Cationic and silicon substituents are introduced into polysaccharides thereby producing modified polysaccharides cationically substituted by quaternary ammonium groups and having a charge density of about 0.1 to about 2.5 meq/g, and further substituted by siliconate groups such that the modified polysaccharide has a silicon content of about 300 to about 5000 ppm. The modified polysaccharides have application in industrial, home care and personal care surface modifying formulations.

A personal care composition including at least one dry emollient and one oily emollient, where the personal care composition is free of silicone or silicone containing materials.

The present disclosure relates to thermoresponsive oil-in-water nanoemulsions that include: (a) one or more amphiphilic triblock copolymers; (b) one or more oils in the form of nanoemulsion droplets having an average size of about 20 nm to about 500 nm; (c) about 5 to about 40 wt. % of one or more surfactants; (d) one or more nonionic co¬ surfactants; and (e) water, wherein the nonemulsion undergoes a sol-to-gel transition at about 20° C. to about 50° C. One or more lipophilic active ingredients and/or one or more hydrophilic active ingredients may be incorporated into the nanoemulsions. The nanoemulsions are particularly useful for medical, pharmaceutical, and cosmetic applications.

A hair conditioner composition comprising: a. an aqueous carrier; b. from about 1 wt % to about 12 wt % of BVE; and c. from about 1 wt % to about 12 wt % of at least two fatty alcohols.

Disclosed is a shampoo comprising from 1 to 15 wt % alkyl sulfate surfactant, ethoxylated alkyl sulfate surfactant or mixture thereof; from 0.5 to 12 wt % fatty acyl isethionate; and from 0.01 to 2 wt % cationic polymer, wherein the cationic polymer comprises cationic galactomannan and cationic cellulose. The shampoo is substantially free of silicone conditioning agent.

A personal care composition and methods for determining a stability of the personal care composition are disclosed. The personal care composition may include an emulsion of a hydrophobic phase and a hydrophilic phase. The hydrophobic phase may include an emulsifying system including one or more amino acid surfactants, such as a glutamate surfactant.

A method of using a hair care composition that cleans the hair and removes dirt and product build up, while also leaving the hair feeling clean, lightly conditioned and/or untangled, as demonstrated by the wet combing and hair feel tests. The hair care composition includes a surfactant, a rheology modifier, and an aqueous carrier, wherein the composition has a pH ranging from about 2 to about 4 as measured by taking a direct pH measurement using a standard hydrogen electrode of the composition at 25° C. Additionally, the viscosity of the aqueous composition is from about 3,000 cP to about 15,000 cP.
