Abstract:
What is described herein is a stable and reduced-yellowing/non-yellowing synergistic preservative composition comprising: (i) about 0.1 wt. % to about 40 wt. % of dehydroacetic acid (DHA); and about 0.1 wt. % to about 99.9 wt. % of at least one aprotic solvent. Also described herein are aqueous and non-aqueous based preservative compositions for various end-user applications, and processes for preparing and using such compositions to reduce yellowing of DHA when added to the end-user applications.

Abstract:
The present invention provides microcapsules with better capsule breakage characteristics, the microcapsules comprising internal phase encapsulating capsule breakage enhancing substances, applications of these microcapsules in oral care, particularly in microencapsulated flavours released during tooth brushing. Accordingly, the capsule breakage enhancing substance is in the size range of 1% to 99% of average microcapsule size most preferably 10% to 30% of the microcapsule size.
Abstract:
The present invention relates to the field of cosmetics and, more particularly, to the field of protective cosmetic skincare. The invention relates to the cosmetic use of an Artemia salina extract to protect skin from damage caused by thermal stress, in particular from cold thermal stress or repeated temperature variations. The invention also relates to a method of cosmetic care comprising topical application, on at least one portion of the skin of the body or face, of an Artemia salina extract, in a composition comprising a physiologically acceptable medium, to achieve a protective effect, and more particularly to protect skin from damage caused by thermal stress.

Abstract:
This invention provides hydrophobic compositions for forming hydrophobic toner receptive coatings on a substrate. The hydrophobic coating compositions for forming toner receptive coatings on a substrate contain a hydrophobic polymer comprising: (a) a N-vinyl amide monomer, (b) a non-reactive hydrophobic monomer moiety, and (c) a solvent. The coating compositions may further comprise (d) a substituted or unsubstituted monomer comprising a cyclic ether or an acetoacetate, or mixtures thereof. The invention also provides compositions suitable for addition to toner to enhance adhesion and toner substrates coated with the hydrophobic coating compositions. The hydrophobic polymer may be represented by the following structure, wherein x, y, z, and a, are defined herein.
