The present disclosure relates to methods for extraction of biomass. Biomass of most interest is that which contains biologically active, extracts suitable for the skin care market. The biomass of interest includes botanicals (plant extracts and bioferments thereof), algae (red, brown, green and red, including bioferments thereof), fungi and even animal extracts (insect, crustacean) origin. Further the use of said extracts in cosmetic preparations prepared by the disclosed method is envisioned.

The invention relates especially to a composition in the form of an oil-in-water emulsion comprising an inner fatty phase and an outer aqueous phase and containing: a) at least 0.01% by weight and preferably at least 0.05% by weight, relative to the total weight of the composition, of at least one inulin modified with hydrophobic chains, and b) at least 0.05% by weight and preferably at least 0.1% by weight, relative to the total weight of the composition, of at least one thickening polysaccharide of plant origin, the said composition being free of silicones. The invention also relates to a cosmetic process using the said composition.

Water-soluble refill dose articles for forming a cleanser have a water-soluble film defining a first compartment enclosing a first composition and a second compartment enclosing a second composition, which are individual separate articles or are part of an integral article. The first composition has a rheology modifier, a first surfactant, 10% or less by weight water, 20% or less by weight glycol, and the first surfactant does not activate the rheology modifier. The second compartment has an alkaline substance that when mixed with the first composition and water activates the rheology modifier to increase the viscosity of a resulting cleanser and 10% or less by weight water. When the article is diluted in water at a 1:1 to 1:20 ratio, it produces a cleanser having a viscosity within a range of 2000 cps to 50,000 cps.

Described herein, a water-soluble personal cleansing product, its uses, methods and kit, preferably a water-soluble facial cleansing product, comprising a water-soluble fibrous structure; wherein the water-soluble fibrous structure comprises a plurality of fibrous elements; wherein the plurality of fibrous elements comprises: one or more fibrous element-forming materials comprising one or more hydroxyl polymers comprising a natural starch and/or a modified starch; wherein the plurality of fibrous elements is substantially free of surfactant; wherein the water-soluble personal cleansing product comprises one or more surfaces wherein the one or more surfaces are coated with an oily composition, wherein the oily composition comprises one or more oil ingredients. Alternatively, the one or more surfaces are coated with a cleansing composition comprising one or more surfactants; and wherein the cleansing composition is substantially free of alkyl sulfate and alkyl ether sulfate type of surfactants.

The present disclosure relates to gentle cleanser compositions, which generally include: (a) a taurate surfactant; (b) salicylic acid; (c) kaolin; d) a betaine (and/or another amphoteric surfactant) and e) an emollient. The cleanser compositions exhibit very good cleansing properties, are particularly effective for removing makeup, and are mild and moisturizing to the skin, with a good deposition of salicylic acid.

The invention relates to a method for producing free powder particles of polyamide, impregnated with at least one cosmetic or pharmaceutical agent. The present invention also relates to free powder particles of polyamide having a content of at least 25% by weight of a cosmetic or pharmaceutical agent other than water, to the use of said particles in a cosmetic, pharmaceutical or perfumery products, and to compositions containing such particles.
