This month’s survey of recent patent and research literature describes money-making ideas for personal care product development, including whitening and skin wrinkle-fighting women’s underwear, heated sunless tanners for rapid color development and collagen stimulation via beta-thujaplicin, among others.
Skin and Skin Care
Skin lightening preparation: Beiersdorf AG used 3-(4-hydroxy-3- methoxyphenyl)-1-(4-hydroxyphenyl)-propane-1-one to address hyper- pigmentation in cosmetic and dermatological preparations.
Heated sunless tanner for rapid color: Unilever PLC disclosed a sunless tanning product that imparts faster color to skin when dispensed through a heating device. At RT, a body lotion containing 1.50% dihydroxyacetone as the tanning agent was prepared and applied to a panelist. The preheated sample delivered a bronze glow within five minutes while an identical, non-heated sample required more than double the time to achieve similar coloration.
Improved moisturization with heated niacinamide: Unilever PLC has also found that heated niacinamide improves skin moisturization. A body lotion containing 1.50% niacinamide together with glycerin, stearic acid, magnesium aluminum silicate, silicone, glyceryl monostearate/stearamide AMP, isopropyl myristate, petrolatum, triethanolamine, glycerol monostearate, cetyl alcohol, fragrance, DMDM hydantoin, titanium dioxide, disodium EDTA and water was prepared and applied to a panelist. The preheated composition imparted more rapid moisturization than expected when compared with the non-heated sample at RT, which resulted in drier, less moisturized skin.
