Described herein is a new process for the preparation of core-shell microcapsules. Microcapsules are also described herein Perfuming compositions and consumer products including said capsules, in particular perfumed consumer products in the form of home care or personal care products, are also described herein.

A water-in-oil personal care emulsion with water droplets size below 20 microns, the droplets containing solubilized cystine. A process of making an emulsion is also described.

The present invention provides a bicontinuous microemulsion composition, including: (A) polyglycerin group-containing organo(poly)siloxane shown by the general formula (1): ##STR00001##
wherein R.sup.1 represents an alkyl group or a phenyl group, R.sup.2 represents a group having a polyglycerin structure shown by the formula (2) or the formula (3), R.sup.3 represents R.sup.1 or R.sup.2, “a” is 0 to 6, “b” is 0 to 4, a+b is 0 to 10, and at least one of R.sup.3 is R.sup.2 when “b” is 0: ##STR00002##
wherein R.sup.4 represents an alkylene group or an aralkylene group, “c” is 0 to 10, and “d” is 2 to 6; (B) silicone oil having a viscosity of 20 mm.sup.2/s or less at 25° C., volatile hydrocarbon oil, or ester oil; and (C) water. This provide a transparent bicontinuous microemulsion composition in which anionic or cationic surfactant, and water-soluble monovalent or polyvalent alcohol are unnecessary; and a cosmetic with excellent pleasantness of use.

Reduced-ethanol perfume compositions according to the invention comprise specific combinations of acrylates/VA copolymer and acrylates copolymer in an aqueous base or delivery vehicle. The perfume compositions according to the invention are easy to manufacture and provide an aqueous perfume composition that preserves aromatic integrity (intensity, duration and range), even in emulsion form. The most advantageous use of compositions of the invention are as parfums, eau de parfums, eau de toilettes, and colognes. However, the invention may also find use in many types of fragranced products, such as those used on the skin and hair of humans or animals, in cleaning products of all types, in air deodorizers, air fresheners, and more.

Methods for enhancing fragrance on skin upon initial application of a rinse-off cleansing composition can include combining surfactant, perfume, solvent, and water, to form the composition, wherein the composition has a total GCMS count higher than that of a control where the solvent is replaced with water when the total GCMS count is measured in accordance with the PSHAM method immediately following the initial application.

Disclosed are: a co-emulsified composition containing different emulsification particle sizes; and a method for preparing the same. The co-emulsified composition contains an amphipathic anisotropic power and a surfactant, thereby allowing emulsification particles with different sizes to coexist in one dosage form, and thus a co-emulsified composition can be provided that simultaneously implements two or more feelings of use or physical characteristics.

A composition that includes a novel association of antioxidant acids demonstrates an unexpected synergistic antioxidant effect that is relevant for the topical treatment of signs of aging and reducing cutaneous lipid peroxidation. The composition includes (a) gallic acid, (b) ferulic acid, (c) ascorbic acid (Vitamin C), and (d) salicylic acid, all present in the composition in amounts sufficient to produce the synergistic antioxidant activity. In some embodiments, gallic acid is present in an amount that is in the range from about 1% to about 10%, and in some examples, in an amount that is at least about 5%.

Disclosed is a process for preparing an encapsulated fragrance composition. The composition comprises a plurality of microcapsules dispersed in a dispersion medium. The microcapsules comprise a core and a shell around the core. The process comprises the consecutive steps of: a) Providing an aqueous phase (I) comprising at least one anionically modified polyisocyanate (A); b) Providing an organic phase (II) comprising at least one fragrance ingredient; c) Mixing the aqueous phase (I) and the an organic phase (II) to obtain a mixture; d) Forming an emulsion comprising droplets of the organic phase (II) in the continuous aqueous phase (I); e) Adding at least one polyfunctional amine; f) Effecting formation of shells around the droplets formed in step d), to obtain a dispersion of microcapsules.

The process comprises the additional step of adding a polyisocyanate (B), which is different from polyisocyanate (A).

The present invention provides nanoparticle compositions including one or more peptides. The present invention achieves transdermal delivery of such peptides without the need for peptide modification, or for use of chemical or mechanical abrasion or disruption of skin.

Disclosed are stable, non-irritating, skin treatment active agents containing formulations and delivery systems for topical application to the skin. The disclosed topical formulations and delivery systems provide controlled, gentle release of the active agents into the skin for the treatment of amenable skin conditions as well as for improvement of aesthetic skin properties. Also provided are methods for the formulation, manufacture and use of the disclosed formulations and delivery systems.
