  • Transparent or translucent emulsions, process for preparing them and cosmetic use thereof
    Patent number: 6616917
    Abstract: The invention relates to a transparent or translucent cosmetic emulsion comprising an aqueous phase, a fatty phase and a surfactant, the said fatty phase containing a miscible mixture of at least one cosmetic oil and of at least one volatile fluoro compound, the latter compound being present in a proportion such that the refractive index of the fatty phase is equal to ±0.05 of that of the aqueous phase. The invention also relates to the process for preparing the emulsion. Use of the emulsion in skincare, hair conditioning and antisun protection and/or artificial tanning.

  • Photoprotective compositions comprising mutually incompatible oily dispersed phases
    Patent number: 5866148
    Abstract: Topically applicable, water resistant cosmetic/dermatological compositions well suited for enhanced photoprotection of human skin and or/hair against the damaging effects of UV-A and UV-B irradiation, particularly solar radiation, comprise (I) a continuous aqueous dispersing phase, (ii) a first discontinuous globular oily dispersed phase O.sub.1, (iii) a second discontinuous globular oily dispersed phase O.sub.2, (iv) at least one O/W emulsifying agent, (v) at least one W/O emulsifying agent, (vi) a photoprotecting effective amount of at least one lipophilic UV screening agent, (vii) a photoprotecting effective amount of at least one hydrophilic screening agent, said first and second oily phases O.sub.1 and O.sub.2 being mutually incompatible, and the globules constituting said oily phase O.sub.1 having an average size which is different from the globules constituting said oily phase O.sub.2.
