A method for reducing muscle contraction of a facial muscle or reducing the appearance of a fine line or wrinkle is disclosed. The method can include topical application of a composition to facial skin and/or to the fine line or wrinkle. The composition can include an effective amount of Rosmarinus officinalis leaf extract, an effective amount of Lavendula stoechas extract, and an effective amount of Acmella oleracea extract. Topical application of the composition to facial skin can reduce muscle contraction of the facial muscle. Topical application of the composition to the fine line or wrinkle can reduce the appearance of the fine line or wrinkle.

A reductive composition, suitable for the dental industry, which utilizes sodium dithionite may be provided when it is combined with either polyethyloxazoline or polyvinylpyrrolidone. Other dithionite molecules, such as potassium dithionite, may be used. Likewise, the methods described herein may be applied to other reductive agents.

A cosmetic composition containing rose stem cell-derived exosomes as an active ingredient is provided for skin regeneration, skin elasticity improvement or skin wrinkle reduction. The cosmetic composition has excellent effects on skin regeneration, skin elasticity improvement and/or skin wrinkle reduction.

A medical device or solution for treating dental discomfort by at least partially occluding dental tubules is disclosed. The medical device or solution contains a polysaccharide or other biocompatible polymer with an antimicrobial metal, antimicrobial metal compound, or antimicrobial metal ion bound to a biopolymer. The medical device or solution further comprises at least one soluble antimicrobial. The soluble antimicrobial may be a water soluble metal iodide, water soluble metal fluoride, or a water soluble metal chloride encompassed with the nanogel. The medical device may be a solution of a chitosan with a nanoparticle of silver fluoride on the chitosan and at least one of a sodium fluoride or silver fluoride. The solution may be water based solution. Methods of applying the medical device or solution are also disclosed.

A personal care composition and methods for generating increased foam volume in the personal care composition are disclosed. The personal care composition may include a carrier and at least two hydrocolloids, wherein the at least two hydrocolloids are present in an effective amount to produce increased foam volume. The method may include contacting a carrier of the personal care composition with at least two hydrocolloids. The at least two hydrocolloids may include xanthan gum and carrageenan in a ratio of from about 1.5:1 to about 9:1.

The present invention relates to a process for the preparation of crosslinked hyaluronic acid butyrate or crosslinked hyaluronic acid butyrate-formate or an acceptable salt thereof, wherein the process comprises the crosslinking reaction of hyaluronic acid butyrate or hyaluronic acid butyrate-formate or a pharmaceutically acceptable salt thereof in an organic solvent with a carboxyl activating reagent, characterized in that the hyaluronic acid butyrate or hyaluronic acid butyrate-formate or pharmaceutically acceptable salt thereof is a mixture of a high-molecular-weight polysaccharide and a low-molecular-weight polysaccharide.

The present disclosure provides a composition for hair and fiber treatment which supplies a transition metal as a catalyst to a thiol residue formed when hair or fiber is damaged in a process of chemical or physical care, and rapidly and abundantly binds an olefin-based unsaturated hydrocarbon through a thiol-ene reaction, thereby continuously providing smoothness to the hair and fiber.

The instant disclosure relates to a rheological-modifying and stabilizing polymer blend, cosmetic compositions comprising the polymer blend, and methods for stabilizing, for modifying viscosity, and for treating the skin using the polymer blend or using cosmetic compositions comprising the polymer blend. The rheological-modifying and stabilizing polymer blend comprises: (i) a carbomer; (ii) acrylates/C10-30 alkyl acrylate crosspolymer; and (iii) ammonium acryloyldimethyltaurate/steareth-25 methacrylate crosspolymer.

The invention relates to new oil gelling polyurethanes useful for preparing clear gels in organic media (oils, solvents) and to a process for their preparation. The invention also relates to the gels formed from these gelling polyurethanes and to compositions containing them, in particular cosmetic compositions.

A dispersion containing a dispersed phase comprising drops and a continuous aqueous phase, preferably in the form of gel, in which the drops comprise a fatty phase containing at least one gelling agent, and in which the fatty phase comprises at least one non-volatile hydrocarbon oil H1 containing more than 90%, and preferably more than 95%, fatty acids having at least 18 carbon atoms and preferably at least 20 carbon atoms.
