Suggested are new extracts of microalgae selected from the group consisting of (i) Monodus sp. (ii) Thalassiosira sp. (iii) Chaetoceros sp. and/or (iv) Chlorococcum sp.
obtainable by treating said microalgae with a solvent selected from the group consisting of C.sub.1-C.sub.4 aliphatic alcohols, ethyl acetate, water or their mixtures, removing the dissolved extracts from the residues and recovering the pure extracts from the solvent. The extracts show excellent properties particularly in modulating the metabolism of human skin and hair follicles.

Fabric care compositions comprising bi-modal water continuous emulsions are disclosed. In particular, the fabric care compositions comprise a bi-modal water continuous emulsion (E) comprising at least 70 weight percent of: a first dispersed phase containing a hydrophobic oil, wherein the hydrophobic oil is provided as a non-emulsified hydrophobic oil, and a second dispersed phase containing a silicone, wherein the silicone is provided from a water continuous silicone emulsion containing at least one surfactant. The fabric care compositions further comprise at least one fabric care ingredient (F). Optionally, the fabric care ingredient (F) is in an acceptable medium. Preparation methods and uses of the fabric care compositions are also disclosed.

A process for preparing a composition (C.sub.1) represented by the formula (I): HO—CH.sub.2—(CHOH).sub.n—CH.sub.2—O-(G).sub.x-H, in which G represents the remainder of a reducing sugar, n is an integer equal to 2, 3 or 4 and x, which indicates the mean degree of polymerization of the remainder G, represents a decimal number greater than 1 and less than or equal to 5, characterized in that the process includes at least one step a) of reacting a polyol of formula (A.sub.1): HO—CH.sub.2—(CHOH).sub.n—CH.sub.2—OH, in which n is an integer equal to 2, 3 or 4, with a reducing sugar of formula (II): HO-G-H, in which G represents the remainder of a reducing sugar, in the presence of an acid catalyst (C.sub.a), and in that the acid catalyst (C.sub.a) is chosen from phosphorous acid, phosphoric acid and polyphosphoric acid.

A preservative composition is described that may be used in personal care products and other products for protecting the products against bacteria and fungus during production and during use. The composition can about 3 to about 15% by weight of an organic acid; about 3 to about 15% by weight of a C.sub.8-C.sub.18 fatty alcohol; about 30 to about 60% by weight of an aromatic alcohol; and about 30 to about 60% by weight of an organic solvent.

Described are compositions containing quinones that show activity in enhance DNA repair and/or prevent damage to DNA and/or upregulate genes associated with wound healing. The quinones are thymoquinone, lapachol, myrtucommulone C, or mixtures thereof, and can be formulated into cosmetic compositions for topical administration to a subject in need thereof. The cosmetic compositions can also include sunscreens, surfactants, sunless tanning agents, desquamation agents, antiperspirants, colorants, preservatives and mixtures; and a cosmetically acceptable carrier. The compositions should find use in methods for treating the signs of ageing in mammals, dermatitis and wound healing via topical application to a site in need thereof, such as the skin or hair of the mammals or a wound site.

The present invention provides a hair care active agent comprising taxifolin glucoside and N-acetyl tyrosine and a hair care composition comprising said hair care active agent. The hair care agent is able to reduce the occurrence of grey and white hair in an individual.

The invention relates to a compound (1) comprising at least 50% by weight of a functional agent, characterized in that it also comprises a waxy matrix (3), within which said functional agent is dispersed, wherein said compound (1) is solid at room temperature and intended to be dispersed by fluidization and/or solubilization within a cosmetic and/or dermatological composition to incorporate therein said functional agent, said functional agent being formed from solid particles (2) having undergone a surface treatment resulting in a reductions in the absorption capacity of the waxy matrix (3) by said treated solid particles (2), as compared to untreated solid particles of the same nature. The invention also relates to a formulation of cosmetic and/or dermatological compositions.

The present invention is directed to previously identified inhibitors of cAMP efflux (ICE) and their use in treating/masking body odor, inhibiting, reducing and/or eliminating hyperhidrosis (excessive sweating), tanning skin or protecting skin before and/or after exposure to the sun as well as for treating certain skin conditions, in one embodiment, the invention provides a method for inhibiting body odor, a condition that is characterized by an unpleasant odor from the products of the microbial sweat degradation. By inhibiting the efflux of the precursor compounds that are degraded, novel compounds are capable of preventing unwanted odors. Deodorant compositions that employ this new approach for the control of bodily odor are provided, ICE compounds can also be used as components, of cosmetic formulations including tanning and after-sun formulations, formulations for skin conditions as described herein and other cosmetic formulation.

The present invention generally relates to systems and methods for treating vitiligo. In one set of embodiments, the present invention comprises a composition comprising pyruvic acid and/or a pyruvate salt. The composition may be formulated for application to the skin of a subject, for instance, as a gel, lotion, cream, ointment, soap, or stick. In some cases, the composition may comprise a lecithin, such as phosphatidylcholine. In certain embodiments, the lecithin is present as a liquid crystal, and/or in liposomes, micelles, or other vesicles.
