  • Sunscreen and personal care compositions comprising a select copolymer
    Publication number: 20080247975
    Abstract: Topically applicable, water-resistant cosmetic or dermatological compositions well suited for the UV-photoprotection of human skin and/or hair comprising an effective UV— photoprotecting amount of: (a) at least one UV screening agent; (b) at least one select copolymer; and, optionally (c) other cosmetically acceptable ingredients. The present invention also relates to personal care compositions comprising at least one select copolymer and other cosmetically acceptable ingredients.

  • Sunscreen compositions
    Patent number: 7108860
    Abstract: The present invention is directed to a cosmetic composition that has an amount of at least two rheology-modifying agents such that the viscosity of the composition remains stable over a broad temperature range. The compositions of the present invention may also include at least one of the following additional components: sunscreen agent, SPF booster, secondary emulsifier, emollient, moisturizer, humectant, film former/waterproofing agent, bio-active (functional) ingredient, pH adjuster/chelating agent, preservative, fragrance, effect pigment, color additive, or any combinations thereof.

  • In vitro prediction of sunscreen PFA values
    Patent number: 7033577
    Abstract: An in vitro method for the prediction of in vivo UVA protection by a composition with sunscreen properties. The method includes the steps of: determining in vivo SPF; determining in vitro SPF based on the sunscreen's absorbance spectrum in the UV region; normalizing the absorbence spectrum based on integration area of UVA1; and calculating the PFA-PPD in vitro.

  • Sunscreen composition
    Patent number: 7014842
    Abstract: There is provided a composition comprising one or more photoactive compounds and one or more optimization agents. Surprisingly, the composition requires a small amount of optimization agent to efficiently optimize the polarity, critical wavelength, SPF, PFA, Star Rating, photostability, or any combinations thereof, of the composition. Subsequently, an efficient sunscreen composition is achieved.
