Abstract: A launderable and reusable, leak-proof, breathable fabric and, more specifically, a composite fabric comprised of a liquid absorptive layer and a liquid impervious but vapor permeable layer. Such fabric is useful in drawing fluids, such as bodily fluids, away from a source, such as the body, and retaining them within the absorptive layer while evaporation thereof takes place though the vapor permeable layer. This material consists of two juxtaposed layers. The inner layer has the characteristic of being liquid permeable so as to allow the body fluids to flow into it and be absorbed. The outer layer has the characteristic of being liquid impermeable but air or vapor permeable, so that the liquid absorbed in the inner layer does not strike through the outer layer.

Abstract: A composition comprising a pigment particle that is coated with a cationic material and isopropyl titanium triisostearate. The pigment particle can be included in a cleansing composition for deposition on a surface, such as skin.

Further provided is a composition, such as a cosmetic composition, which includes the porous particulates loaded with the UV attenuating nanoparticles.

Abstract: A wax-resin composite is made by melting thermoplastic hydrocarbon resin, optionally with an antioxidant. The melted thermoplastic hydrocarbon resin and waxes are blended at a temperature sufficient to melt the waxes. After blending and melting, the blended thermoplastic hydrocarbon resin and waxes are allowed to solidify. Solidification is followed by post-processing the wax-resin composite mixture to form slabs, pastilles, flakes or other forms. A method for producing a wax-resin composite comprises at least partially solvating a thermoplastic resin in a solvent to form a resin-solvent blend. This may be done at a heat of 80-85° C. A composition of molten wax is blended with the resin-solvent blend. The resin-solvent blend and a molten wax are blended to form a wax-resin blend. This is followed by removing the solvent from said wax-resin blend.

Abstract: Large particle sunscreen powders useful as ingredients in cosmetic compositions and in dispersions for incorporation into cosmetic compositions comprise a UV shielding agent in a matrix material. The macroparticle powders can be used in a wide range of cosmetic formulations, including sunscreens, eyeshadow, mascara, foundation, blusher, toner, lipstick and other compositions requiring ultraviolet protection.

Abstract: Disclosed is a composition that comprises an effective proportion of a first metal oxide powder having a primary particle size and a secondary particle size selected for the first metal oxide powder to attenuate UVA and an effective proportion of a second metal oxide powder having a secondary particle size selected for the second metal oxide powder to attenuate UVB. The mean secondary particle size of the first metal oxide powder is greater than the mean secondary particle size of the second metal oxide powder. In one embodiment, the first and the second metal oxide powders are both zinc oxide.

Abstract: A hybrid coating material and process for pigments and other powders, for example cosmetic powders employs an organometallate, for example a titanate, and a functionalized silicon compound, for example a trialkoxysilane or a functionalized polysiloxane, which covalently bond to each other and to the substrate powder. The coated powders can exhibit excellent hydrophobicity coupled with lipophilicity. Employment of fluorinated silicon compounds may provide hydrophobicity and lipophobicity. Examples show good dispersibility of coated pigments in aqueous, oil and silicone fluids.

Abstract: Novel organosilicon-treated cosmetic powders, for example, a pigment, extender pigment or filler are free from residual hydrogen, have a smooth feel, good skin adhesion, good color and spreadability and resistance to acids and alkalis. The treated powders are useful in cosmetics such as powder formulations, oil-in-water and water-in-oil emulsions, anhydrous make-up and lipstick. Treatment can be effected with a linear reactive alkylpolysiloxane having substituted in repeating units in the backbone of the molecule both cationic and anionic groups, for example aminoethylaminopropyl and alkoxy groups. The organosilicon compound can be adsorbed and chemically bonded to the surface of the powder by heat treatment. The alkylpolysiloxane compound can have a degree of polymerization of from 5 to 100, preferably 10-15. A process for producing the treated pigment is also disclosed as are cosmetic formulations made with the treated pigment.

Abstract: Hard-to-coat color lakes and other powders useful in cosmetics and other industries are coated with a duplex coating system comprising basic and nonbasic functionalized coating components, for example a basic functionalized aminopolysiloxane and a nonbasic alkoxypolysiloxane. Control of bleeding of a color lake into aqueous media is possible. A novel duplex coating system, treatment process, treated powder and cosmetic formulation containing same are disclosed.
