Compositions comprising unsaturated fatty chains have reduced or eliminated base off-odour with the incorporation of a photobleach.

An antiperspirant / deodorant liquid composition comprising a solvent, an antiperspirant and / or deodorant ingredient, a fragrance, and an alkylated polyvinylpyrrolidone, wherein the alkylated polyvinylpyrrolidone is soluble or dispersible in the composition. The alkylated polyvinylpyrrolidone is capable of forming a film when the solvent is allowed to evaporate such that the film limits the release of the fragrance. Fragrance is released when the film is exposed to perspiration. The alkylated polyvinylpyrrolidone overcomes the problem with other film forming polymers that do not form stable films in the presence of an antiperspirant and / or deodorant ingredient.

This compound can be incorporated into fiber conditioning compositions, such as hair conditioners and fabric softeners, to enhance the fragrance performance. The compound provides controlled release from the substrate where it has been deposited over an extended period of time.

The invention discloses an amphiphilic chitosan and a preparation thereof. The amphiphilic chitosan is chitosan grafted with stearic acid and N-acetyl-L-cysteine ​​and has a molecular weight of 10-300 kDa. When the amphiphilic chitosan of the present invention is used as a nano-microcapsule embedding wall material, it can embed hydrophobic substances to form water-soluble nano-microcapsule solids, and can also be used as an embedding wall material for hydrophilic substances to form Non-water-soluble nano-microcapsules. The invention also discloses an amphiphilic chitosan-macadamia nut oil nano-microcapsule and its preparation method and application. The nano-microcapsule is formed by embedding a core material in a wall material, the core material is macadamia nut oil, and the wall material is The amphiphilic chitosan provided by the invention. The nanometer microcapsule provided by the invention has high embedding rate, good dispersibility and uniformity, and after the macadamia nut oil is embedding with amphiphilic chitosan, the volatility is reduced, and the stability and bioavailability are significantly improved.
