The present disclosure relates to hair care systems comprising: (1) a booster composition containing at least one ionic polymer functionalized with at least one carboxylic acid moiety; optionally, at least one compound selected from an alkoxysilane, a nonionic latex polymer, or mixtures thereof; a thickening agent; and a cosmetically acceptable carrier; and (2) a hair treatment composition containing at least one surfactant selected from an anionic surfactant, an amphoteric surfactant, a cationic surfactant, a nonionic surfactant, or mixtures thereof. The hair care systems of the present disclosure can be used to clean and/or condition hair, as well impart frizz control and manageability benefits to hair.

The present invention falls within the general field of cosmetics, and in particular, it relates to a breakable capsule (1) with a membrane (2) and core (3) suitable for releasing an active ingredient comprised in the membrane (2), both for cosmetic use and for pharmaceutical use and to the preparation processes thereof. The capsule (1) has good chemical and mechanical stability wherein the capsule, once applied to the skin, reduces or does not generate residues and, at the same time, any residual trace produced by the membrane (2) can be absorbed or adsorbed by the skin. In addition, they have good stability against light and breakage.

A water-in-oil emulsion composition comprising (a) water, (b) at least one oil, (c) at least one surfactant, (d) at least one water-soluble vinyl polymer, and (e) at least one organosiloxane film-former that is selected from a silicone resin and a random acrylic/silicone graft copolymer is provided. The composition may be a composition for eyelashes, for example a mascara composition further including at least one colorant.

The invention relates to a dispersion of polymer particles stabilized with a stabilizer in a nonaqueous medium containing at least one hydrocarbon-based oil, the polymer of the particles being a C.sub.1-C.sub.4 alkyl (meth)acrylate polymer; the stabilizer being a C.sub.1-C.sub.4 alkyl (meth)acrylate polymer and optionally of a silicone macromonomer (I): the stabilizer being a polymer comprising from 50% to 100% by weight, relative to the total weight of the stabilizer, of C.sub.8-C.sub.22 alkyl acrylate, from 0 to 50% by weight of C.sub.1-C.sub.4 alkyl (meth)acrylate and optionally silicone macromonomer (I).

The invention also relates to the composition comprising said dispersion of polymer particles.

Cosmetic use for caring for and making up keratin materials.

Compositions comprising at least one major ampullate spidroin protein (MaSp)-based fiber, a polymer bound to the MaSp-based fiber, and optionally a further polymer having a molecular weight in the range of 1000 Da to 1000 kDa, are provided. Further, methods for preparation of same are provided.

Disclosed are: a co-emulsified composition containing different emulsification particle sizes; and a method for preparing the same. The co-emulsified composition contains an amphipathic anisotropic power and a surfactant, thereby allowing emulsification particles with different sizes to coexist in one dosage form, and thus a co-emulsified composition can be provided that simultaneously implements two or more feelings of use or physical characteristics.

A chemically anisotropic powder with improved emulsion dispersion stability, and a cosmetic composition containing the same are disclosed in the present specification. The chemically anisotropic powder has a first polymer spheroid and a second polymer spheroid coupled in such a structure in which one polymer spheroid at least partially penetrates the other polymer spheroid, wherein any one of the first polymer spheroid and the second first polymer spheroid comprises a polymer containing siloxane, and one or more of the first polymer spheroid and the second first polymer spheroid are negatively or positively charged, thereby having effects of preventing phase separation even with a minimum amount of a thickening agent and enabling a toner type low-viscosity form containing a high oil content, the toner type low-viscosity form having yet to be applied.

A shampoo composition and a method of making a shampoo composition which delivers both good conditioning benefits and good lather performance. The shampoo composition comprises a dispersed gel network phase comprising: from about 2.8 weight % to about 8 wt % of one or more fatty alcohols; at least 0.01% of one or more secondary surfactants, wherein the secondary surfactant comprises sodium laureth-n sulfate wherein n is from about 0 to about 5; and water; and from about 5% to about 50% of a detersive surfactant; from about 0.02% to about 1.50% of a material selected from the group consisting of structurants, suspending agents and mixtures thereof, from about 0.5 to about 1% of a cationic deposition polymer; and at least 20% of an aqueous carrier.

The present invention relates to a polyelectrolyte complex, and compositions thereof, for use in the treatment or prevention of dental caries, early erosive damage, and enamel demineralization, and the promotion of enamel repair and remineralization. This oral care composition comprises polyelectrolyte complexes comprising cationic polymers and anionic carboxylates.

The present invention relates to a composition comprising particles of at least one polymer that is surface-stabilized with a stabilizer, the polymer of the particles being a C1-C4 alkyl (meth)acrylate polymer; the stabilizer being an isobornyl (meth)acrylate polymer chosen from isobornyl (meth)acrylate homopolymer and statistical copolymers of isobornyl (meth)acrylate and of C1-C4 alkyl (meth)acrylate present in an isobornyl (meth)acrylate/C1-C4 alkyl (meth)acrylate weight ratio of greater than 4, at least one hydrocarbon-based oil and at least one silicone resin, and a mixture thereof. The invention also relates to a process for making up and/or caring for keratin materials, in which said composition is applied.
