  • the present invention relates to a cosmetic composition, in particular, a biphase composition for cleansing and/or removing makeups from keratin materials.
  • the present invention also relates to a process for cleansing and/or removing makeups from keratin materials using said composition.
  • Cleansing the skin or removing makeups from the skin is very important for caring for the skin. It must be as efficient as possible because greasy residues, such as excess sebum, the remnants of cosmetic products used daily and make-up products, in particular waterproof products, accumulate in the skin folds, and can block the pores of the skin and result in the appearance of spots.
  • Biphase compositions consisting of two separate phases, in particular, an aqueous phase and a fatty phase which are separate, are generally referred to as "biphase compositions" .
  • Biphase compositions appeal to consumers on account of their pearly appearance. The two phases are separate at rest by a single interface.
  • biphase compositions of silicone oils such as cyclopentasiloxane, for example, in a suitable amount may make it possible to obtain biphase compositions consisting of two separate immiscible phases which form, after shaking, an emulsion, while keeping the desired properties for the biphase compositions, i.e. rapid phase separation into two transparent phases.
