Definitions

  • the present invention is directed to a composition in the form of an oil- in-water emulsion comprising (a) one or more oil-soluble organic sunscreen ingredient; (b) one or more water-soluble organic sunscreen ingredient; (c) one or more silica-coated titanium dioxide sunscreen ingredient; (d) one or more mattifying powder; (e) one or more fatty compound; (f) an emulsifier system comprising: (i) one or more anionic surfactant, (ii) one or more non-ionic surfactant, (iii) one or more co- emulsifying ingredient; and (g) water.
  • the compositions are particularly useful for preventing and/or controlling skin oiliness.
  • the compositions are also useful for protecting the skin from damage caused by ultraviolet radiation.
  • UV-filter compounds and/or particulate UV-screening compounds (collectively, “sunscreen ingredients”) that are solubilized, emulsified, or dispersed in a cosmetically or physiologically acceptable carrier, which is topically applied to the skin.
  • sunscreen ingredients typically through the aid of polymers and other ingredients included in the vehicle, form a thin, protective, and often water-resistant layer on the skin. Sunscreens can be used to protect against UV damage and delay the signs of aging.
  • Human skin contains sebaceous glands which secrete an oily or waxy substance known as sebum. A build-up of sebum on the surface of skin can cause the skin to appear shiny and/or oily. Shiny and/or oily skin is both uncomfortable and unappealing to many consumers. Shiny and/or oily skin can also highlight skin imperfections and reduce the wearability of other cosmetic compositions.
  • organic sunscreen ingredients are oil-like and/or oil-soluble materials.
  • the degree of UV protection afforded by a sunscreen composition is related to the amount and type of sunscreen ingredients it contains. For example, compositions with higher amounts of sunscreen ingredients may provide a higher degree of UV protection.
  • Sunscreen compositions which may prevent and control skin oiliness are disclosed, for example, in WO 2013/1022848.
  • the disclosed compositions contain an emulsifying agent, a water-soluble sunscreen ingredient, an oil-soluble sunscreen ingredient, and up to 7% oil absorbing particles.
  • Oil-soluble sunscreen ingredients tend to contribute to the greasy feel of sunscreen compositions.
  • the compositions disclosed in WO 2013/1022848 contain a greater amount of water-soluble sunscreen ingredients compared to oil-soluble sunscreen ingredients by weight, relative to the total weight of the composition.
  • Example 1 discloses a sunscreen composition comprising 9% water-soluble sunscreen ingredients and 7% oil-soluble sunscreen ingredients by weight, relative to the total weight of the composition. Without wishing to be bound by theory, the composition disclosed in example 1 may be expected to be less greasy and prevent and/or control skin oiliness better than a composition containing a greater amount of oil-soluble sunscreen ingredients compared to water-soluble sunscreen ingredients by weight, relative to the total weight of the composition.
  • the present invention is directed to a composition in the form of an oil- in-water emulsion comprising:
