A method for reducing a presence of sebum on skin, reducing an appearance of shiny skin, or reducing an appearance of the size of skin pores is disclosed. The method can include topically applying to skin a composition comprising a navy bean extract comprising amino acids, an extract of Bambusa vulgaris wendl shoots, and charcoal.

A polyurethane elastomeric rubber composition containing a bio-based polyol cross-linked with a bio-based isocyanate using a urethanation catalyst such as a bismuth catalyst in the presence of a cosmetic emollient is disclosed. The cross-linked polyurethane elastomer rubber is in further aspect of the invention included in a gel after being milled in the presence of a bio-based emollient or mixture of bio-based emollients. The polyurethane elastomeric gel has good compatibility with cosmetic and natural oils and can be used as a gelling agent for these oils among other desirable cosmetic formulary roles.

The invention relates to a hydrogel based on water, on hydrosoluble monomeric or polymeric isosorbide epoxide and on hydrosoluble amine, to the method for preparing same and to the use thereof.

The invention relates to cosmetic and dermatological preparations which comprise a combination of levulinic acid and anisic acid. The preparations according to the invention are particularly suitable for use on skin. The preparations have a selective antibacterial effect on skin by specifically controlling anaerobic bacteria of the skin flora while having little or no bactericidal effect on aerobic bacteria. The compositions according to the invention are therefore suitable for cosmetic skin care and for the dermatological treatment of certain skin disorders, such as acne.

Disclosed are hair care compositions, such as shampoos, conditioners and leave on treatments, containing one or more hydroxylated triglyceride oligomers. Also disclosed are methods of using the hair care compositions.

Described herein, personal cleansing compositions, methods and uses. Personal cleansing compositions can include a surfactant, a perfume, a hydric solvent, and water, wherein the composition is structured.

The present invention generally relates to the field of skin care. More particularly, the invention relates to a cosmetic or therapeutic skin care composition comprising live bacteria of at least one Cutibacterium acnes (C. acnes) strain in combination with an emollient that specifically supports their viability during storage and/or their ability to replicate after application to the skin. Preferably, the cosmetic or therapeutic skin care composition comprises bacteria of at least one C. acnes strain selected from the group consisting of D1, A5, C1, C3, H1, H2, H3, K1, K2, K4, K6, K8, K9, L1, and F4. The invention also provides a method for treating or preventing acne by applying the skin care composition of the invention to a skin area in need of treatment. The invention also relates to the use of a skin care composition of the invention for treating or preventing acne.

It relates to a cosmetic composition in the form of a transparent or semi-transparent gel, comprising (a) an oil phase; (b) a surfactant portion comprising a first non-ionic surfactant and a second non-ionic surfactant; (c) an aqueous phase; and (d) at least one C.sub.2-C.sub.6 polyol; wherein the first nonionic surfactant comprises at least one alkyl polyglucoside and the second nonionic surfactant comprises at least one having the following general formula (I) or (II): R(X).sub.nOR′ (I) wherein, R represents a linear or branched C.sub.8-C.sub.30 alkyl group or C.sub.8-C.sub.30 alkenyl group; X represents —OCH.sub.2CH.sub.2— or —OCH.sub.2—CHCH.sub.3—; n represents an integer from 2 to 100; and R′ represents H, or a linear or branched C.sub.8-C.sub.30 alkyl group or C.sub.8-C.sub.30 alkenyl group; (II) wherein, the sum of x+y+z represents an integer from 2 to 100; and R.sub.1, R.sub.2, and R.sub.3, are the same or different and are each independently represents OH, or a linear or branched C.sub.8-C.sub.30 fatty acid ester group, with the proviso that at least one of R.sub.1, R.sub.2 and R.sub.3 is not OH. It also relates to a method for preparing the cosmetic composition and the use thereof. The cosmetic composition has high oil content, superior stability and desirable cleansing efficacy.
