Definitions

  • the present invention belongs to the cosmetic field, and relates to a sunscreen composition without cyclomethicones, especially in form of an emulsion, more especially in form of a W/O-emulsion.
  • UVA and UVB filters are summarized in most industrialized countries in the form of positive lists such as for instance Annex 7 of the German Cosmetics Regulation.
  • the effect of UV filters in a cosmetic preparation has to be determined; in general the sun protection factor (SPF) is used to characterize the sun protection potential of a cosmetic composition intended for the use as a sunscreen means.
  • the sun protection factor (SPF) indicates the increased time of exposure to the sun's rays made possible through use of the sunscreen composition. It is the ratio of the erythema threshold time with sunscreen composition to erythema threshold time without sunscreen composition.
  • a cosmetic composition may be characterized by SPF values of 20 or 50.
  • SPF values 20 or 50.
  • a high amount of UV filters has to be used in said compositions. This may result in compositions, which are highly viscous or even paste-like and difficult to distribute. Moreover, said compositions may stay visible on the skin in form of white films.
  • Sunscreen compositions which are provided in form of a W/O emulsion, help to make available a light product capable of being distributed in an easy and even manner.
  • a further means to ensure a pleasant skin feeling without any greasiness and oiliness is the use of cyclomethicones.
  • Cyclomethicones may be characterized by the following formula:
  • n is from 3 to 30.
  • cyclomethicones with n representing 4 to 6 are mainly used. These components have the property to reduce the stickiness of cosmetic preparations. They are colorless and thin fluid.
  • cyclotetrasiloxane (D4) is considered as presumably affecting fertility and being harmful for aquatic organisms. Furthermore, the degradability is slow and therefore this substance may be accumulated in living organisms.
  • Cyclopentasiloxane (D5) may be absorbed and resorbed by the human organism because of its high volatility.
  • the sunscreen compositions without cyclomethicones should provide compositions with high SPFs, at the same time being easily spreadable, optionally available as very fluid compositions and/or water-resistant.
  • ester and/or diester o at least one ester and/or diester, with the proviso that the ester and/or diester is not a UV filter, and/or

  • emulsions are heterogeneous systems, which consist of two liquids which are immiscible or have only limited miscibility with one another and which are usually referred to as phases.
  • one of the two liquids is dispersed in the form of very fine droplets in the other liquid.
  • the liquids pure or as solutions
  • O/W emulsion oil-in-water emulsion
  • the basic character of an O/W emulsion exemplified by electrical conductivity, sensory properties, ability of the continuous phase to be stained, is determined by the water.
  • W/O emulsion water-in-oil emulsion, e.g. butter
  • the basic character is determined by the oil.
  • one or more emulsifier (s) is/are contained in general.
  • Emulsifiers help to combine two immiscible liquids (for example oil in water) in a way to result in a stable preparation, an emulsion. For that reason emulsifiers have to have an amphiphilic character, the hydrophobic part interacts with the oily or lipid phase and the hydrophilic part interacts with the aqueous phase. By stirring or homogenizing the generated droplets are dispersed in the respective environment, namely aqueous droplets in a lipid environment or lipid droplets in an aqueous environment. Primarily, emulsifiers do not have a detersive, surfactant character.
  • Emulsifiers reduce the interfacial tension between the two phases and, besides reducing the interfacial work, also achieve a stabilization of the emulsion formed. They stabilize the formed emulsion by means of interfacial films, as well as by forming steric or electrical barriers, as a result of which the merging (coalescence) of the emulsified particles is prevented.
  • HLB values are suitable to characterize emulsifiers, said values specify the hydrophilicity of a given emulsifier.
  • the HLB value may be determined by the following formula:
  • HLB 20 ⁇ (1-M lipophile /M)
  • M lipophile represents the molar mass of the lipophilic fraction of a given emulsifier and M represents the molar mass of the total emulsifier.
  • emulsifiers with an HLB value up to about 8 are considered to be W/O-emulsifiers.
