The composition may comprise a polymeric adherent material for adhering the metal oxide particles in the dentin tubule. The metal oxide particles have a median particle size of 5 microns or less, and may comprise zinc oxide.

A dissolvable solid structure that is formed by a homogeneous mixture. The mixture includes from about 1% to about 10% of a first polymeric structurant having a molecular weight of from about 1,000,000 g/mol to about 4,000,000 g/mol, from about 10% to about 20% of a second polymeric structurant having a molecular weight of from about 50,000 g/mol to about 500,000 g/mol, from about 10 wt% to about 85 wt% of one or more high melting point fatty material having a carbon chain length C12-C22 or mixtures thereof and a melting point above 25° C., and from about 1 wt% to about 60 wt% of a cationic surfactant. The dissolvable solid structures can provide an adequate strength during manufacturing, while not deteriorating usage feel when used and/or applied by consumers.

Disclosed are injectable dermo-aesthetic formulations comprising aqueous solutions of at least one unmodified high-molecular-weight linear hyaluronic acid or hyaluronate and at least one unmodified low-molecular-weight linear hyaluronic acid or hyaluronate or non-sulphated chondroitin. The compositions according to the invention are useful as fillers with an excellent safety profile, adequate residence time at the site of application, and limited extrusion force.

A method of reducing the appearance of hyperpigmented skin is disclosed. The method can include topically applying to hyperpigmented skin a composition comprising an aqueous and/or glycerin extract of Rhododendron ferrugineum leaf to reduce melanocyte pigmentation in the skin.

The present disclosure relates to a biodegradable polymer dispersion containing a lactic acid-based polymer, a lactic acid-based polymer and polyethylene glycol-containing block copolymer (PEG-PLA), and a hyaluronic acid mixture, wherein the biodegradable polymer dispersion has excellent physiological activity by itself, has excellent dispersion stability of the lactic acid-based polymer, and is capable of effectively supporting active ingredients. In addition, the present disclosure relates to a composition containing the biodegradable polymer dispersion and a skin improvement system.

Provided is a polyurethane gel composition containing A and B below. Here, A represents a polyurethane obtained by reaction of (a) a hydrogenated polybutadiene having isocyanate groups at the terminals and (b) a glycol represented by HO—R.sub.3—OH (wherein R.sub.3 represents a linear or branched C2 to C6 alkylene group optionally having an ether bond), or A represents a polyurethane obtained by reaction of (c) a hydrogenated polybutadiene having hydroxyl groups at the terminals, (d) a diisocyanate compound, and the (b) glycol represented by HO—R.sub.3—OH (wherein R.sub.3 represents a linear or branched C2 to C6 alkylene group optionally having an ether bond), and B represents an oil agent. The polyurethane gel composition of the present invention is particularly useful as a raw material for cosmetics since a film of an oil-soluble gel obtained using the polyurethane gel composition is exceptionally excellent in any point of transparency, high gloss, elasticity, and resilience.

The present invention relates to a composition according to the present invention comprises: (a) at least one particle comprising at least one cationic polymer, at least one anionic polymer, and at least one hydrophilic or water-soluble UV filter; and (b) at least one physiologically acceptable volatile medium. The composition according to the present invention is stable, and can have a variety of cosmetic functions. For example, the composition according to the present invention can prepare a film which can have cosmetic effects such as UV filtering, as well as absorbing or adsorbing malodor, changing the appearance of a keratin substrate such as skin, changing the feel to the touch of the keratin substrate, and/or protecting the keratin substrate from, for example, dirt or pollutants.

Disclosed are compositions for treating and conditioning keratinous substrates, comprising a cationic agent comprising quaternary ammonium compounds; a modified starch; silane compounds, a cationic vinylpyrrolidone polymer and water. Also disclosed are methods treating and conditioning keratinous substrates using the composition.

The present invention provides calcium carbonate-based oral care compositions, in particular toothpastes comprising a thickening system comprising 0.2-0.5 wt. % xanthan gum and 0.2-0.5 wt. % synthetic polyacrylic acid polymer, as well as methods of using these compositions.
