This month’s survey of recent patent and research literature describes money-making ideas for personal care product development, including indirect antioxidants for skin protection, caper and prickly pear extracts to address skin conditions, granulated shampoo and a dual phase mouthwash, among others.
Skin and Skin Care
Polysiloxane emulsifiers: Clariant International Ltd. discloses cosmetic or pharmaceutical compositions, preferably emulsions, utilizing one or more modified polysiloxanes with at least one carbamate group as the emulsifiers.1 An example of an extra moisture night cream is shown in Formula 1.
Vernonia to improve skin: Bayer Consumer Care describes the use of Vernonia extract to improve skin.2 The described invention incorporates a Vernonia plant extract from Madagascar into cosmetics, pharmaceuticals and food supplements to improve the skin by strengthening the dermal-epidermal junction and/or activating fibroblast synthesis and extracellular matrix compounds.
Thus, dried leaves of Vernonia appendiculata were extracted using heptane and percolated with ethanol. The fats were then removed by liquid-liquid extraction, also using heptane. After concentration into the aqueous phase, glycerin was added to adjust the solution to 10% extract in a water-glycerin blend. The final product resulted in a liquid containing > 5% of chlorogenic and isochlorogenic acids. The end Vernonia extract obtained was formulated at 1% into an antiaging cream.
Topical, injectable hyaluronan and heparin: Innoderm has patented topical and injectable cosmetic or pharmaceutical compositions containing a combination of cross-linked or non-cross-linked hyaluronan and heparin and/or one or more heparinoid derivatives.3 These compositions were employed to prolong the lifespan of the hyaluronan present in the skin, which is either endogenous or exogenous, cross-linked or non-cross-linked, in order to improve its antiaging and moisturizing actions and to fill in wrinkles.
