Universal sensory structurants and compositions comprising the same are described. The universal sensory structurants comprise polysaccharide carbohydrate having at least about 75% by weight amylopectin and the polysaccharide carbohydrate has been treated and swollen with a solvent comprising hydroxylated polymer comprising less than about 100 silane repeat units.

Universal sensory structurant

Sunscreen composite particles for UVA and UVB protection are described. The particles are substantially free of supplied UVB sunscreen and are prepared with a UVA sunscreen suitable to undergo keto-enol tautomerization.

Sunscreen composite particles for UVA and UVB protection

Sensory modifiers and compositions comprising sensory modifiers are described. The sensory modifiers comprise polysaccharide carbohydrate having at least about 75% by weight amylopectin and the polysaccharide carbohydrate has been treated and swollen with a substantially anhydrous solvent.

Sensory modifier

A cosmetic composition is provided which includes composite particles of a sunscreen agent and a condensation polymerized polyamide binder, a water-insoluble powdered polymer of porous particles having an Oil Absorbance (castor oil) Value ranging from about 90 to about 500 ml/100 gm, and a cosmetically acceptable carrier. The composition exhibits an excellent soft focus property to hide skin imperfections, and retains relatively high SPF photoprotection.

Sunscreen composite particles and porous particles in cosmetic compostions

A cosmetic composition is provided including a water-insoluble UV-A sunscreen agent having a &#x3bb;at 330-380 nm, a water-insoluble UV-B sunscreen agent having a &#x3bb;between 280 and 320 nm, and a water-soluble sunscreen agent having a &#x3bb;between 280 and 400 nm, in combination with a photo protective enhancing agent which is a stearyl alkanolamide of structure RC(O)NR&#x2014;ROH wherein Ris a Cradical, Ris hydrogen or a C-Cradical, and Ris a C-Cradical, in a cosmetically acceptable carrier.

Sunscreen composition with fatty acid alkanolamides

A cosmetic composition is provided including a water-insoluble UV-A sunscreen agent having a &#x3bb;at 330-380 nm, a water-insoluble UV-B sunscreen agent having a &#x3bb;between 280 and 320 nm, and a water-soluble sunscreen agent having a &#x3bb;between 280 and 400 nm, the water-soluble sunscreen agent being neutralized with metallic counter ions which in a first portion are sodium and in a second portion are potassium ions present in a respective molar ratio of 0.5:2 to 2:1, and a cosmetically acceptable carrier including from 0.2 to 4% of potassium stearate by weight of the composition.

Sunscreen composition

A cosmetic composition is provided which is a vanishing cream structured with 0.5 to 50% by weight of C-Cfatty acid, 0.1 to 20% by weight of C-Cfatty acid salt and hydrophilic composite particles with organic sunscreen agent. The hydrophilic composite particles are formed as a composite of sunscreen agent and a binder in a relative weight ratio of about 5:1 to about 1:10. The composition exhibits relatively high SPF photoprotection while maintaining excellent skinfeel aesthetics.

Sunscreen formula vanishing cream

A cosmetic composition is provided which includes a silicone elastomer, a cationic copolymer with monomeric units selected from at least an acryloylethyl tri(C-Calkyl)ammonium salt, and light reflecting platelet shaped particles. The compositions are particularly useful to impart radiance as well as soft focus effects onto the skin. A particular useful cationic copolymer is that of acrylamide/acryloylethyl trimethylammonium chloride/tris(hydroxymethyl)acrylamidomethane copolymer.

Cationic copolymers formulated with pigmented cosmetic compositions exhibiting radiance with soft focus

A cosmetic water-in-oil emulsion composition is provided which includes composite particles of a sunscreen agent and a condensation polymerized polyamide binder, an emulsifying silicone surfactant sufficient to form the water-in-oil emulsion, an oil phase, and a water phase. The composition exhibits relatively high SPF photoprotection while maintaining excellent soft focus properties that hide skin imperfections.

Sunscreen composite particles dispersed in water-in-oil cosmetic compositions

Composite particles for providing UV photo protection in cosmetic compositions are reported which include an organic sunscreen agent dispersed within a condensation polymerized resin having carboxylic acid groups and a dielectric constant ranging from 6.5 to 18.

Sunscreen composite particles

The present invention relates to beauty wash bar compositions which deliver enhanced visual benefits to the skin with specific optical attributes. This is accomplished using specific deposition systems (where oil/emollient comprises part of deposition system) and/or by ensuring dispersion of particles onto skin.

Beauty wash product bar compositions delivering enhanced visual benefits to the skin with specific optical attributes

A cosmetic composition for sunless tanning or imparting glow to skin is herein described. The composition includes from about 0.1 to about 20% by weight of a tanning agent and from 0.1 to 20% by weight of a crosslinked cationic copolymer having a monomer unit which is a methacryloylethyl or acryloylethyl tri(C-Calkyl)ammonium salt. The crosslinked cationic copolymer is a color enhancing agent which improves color intensity and avoids streaking of the developing tan/glow.

Glow and sunless tanning color enhancement by cationic copolymers

A cosmetic composition is provided which includes hydrophilic composite particles of an organic sunscreen agent, particles of a crosslinked silicone elastomer, and a cosmetically acceptable carrier. The hydrophilic composite particles are formed as a composite of sunscreen agent and binder in a relative weight ratio of about 5:1 to about 1:10. The composition exhibits relatively high SPF photoprotection while maintaining excellent soft focus properties that hide skin imperfections.

Sunscreen composite particles in cosmetic compositions

The invention provides hydrophobically modified cationic polymers which may be used to enhance deposition of particles.

Hydrophobically modified cationic polymers

A cosmetic composition is provided which includes a crosslinked silicone elastomer, a zinc oxide or zirconium oxide of average particle size less than 300 nm and a light reflecting inorganic material of platelet shaped particles having an average particle size of about 10,000 to about 30,000 nm, in a cosmetically acceptable carrier system. The composition achieves soft focus and radiance properties which improve the appearance of skin. Good coverage over imperfections such as pores and uneven skin tone is achieved while retaining a natural skin appearance.
