Abstract
The present disclosure relates to foaming cleansing compositions without anionic surfactant, comprising, in a cosmetically acceptable medium: a) greater than 2% by weight in terms of active material of a non-betaine amphoteric or zwitterionic surfactant, relative to the total weight of the composition, b) at least one non-ionic surfactant, c) at least one propellant. The present disclosure also relates to aerosol devices containing such a composition and also to the use of these compositions in cosmetics or dermatology, for instance for cleansing keratin materials such as the skin, the hair or the scalp.
Claims30
A foaming cleansing composition without anionic surfactant, comprising, in a cosmetically acceptable aqueous medium:
- a) greater than 2% by weight in terms of active material of at least one non-betaine amphoteric or zwitterionic surfactant, relative to the total weight of the composition,
- b) at least one non-ionic surfactant, and
- c) at least one propellant.
A cosmetic process for cleansing and/or removing makeup from human keratin materials comprising applying a composition to the human keratin materials comprising, in a cosmetically acceptable aqueous medium:
- a) greater than 2% by weight in terms of active material of at least one non-betaine amphoteric or zwitterionic surfactant, relative to the total weight of the composition,
- b) at least one non-ionic surfactant, and
- c) at least one propellant.
A process for preparing a formulation for treating oily skin, comprising:
- adding, to a composition comprising, in a cosmetically acceptable medium,
- a) greater than 2% by weight in terms of active material of at least one non-betaine amphoteric or zwitterionic surfactant, relative to the total weight of the composition,
- b) at least one non-ionic surfactant, and
- c) at least one propellant.
- at least one active agent for treating oily skin chosen from anti-seborrhoeic agents.
A cosmetic method for cleansing soiling residues from human keratin materials comprising
- applying to said human keratin materials, in the presence of water, a composition comprising, in a cosmetically acceptable medium,
- a) greater than 2% by weight in terms of active material of at least one non-betaine amphoteric or zwitterionic surfactant, relative to the total weight of the composition,
- b) at least one non-ionic surfactant, and
- c) at least one propellant.
- wherein an aerosol device is used such that the composition is applied as a foam formed at the outlet of the aerosol device,
- massaging the composition to form a foam on the keratin materials and removing the foam formed and the soiling residue by rinsing with water.
An aerosol device comprising at least one compartment comprising therein a foaming cleansing composition comprising, in a cosmetically acceptable medium,
- a) greater than 2% by weight in terms of active material of at least one non-betaine amphoteric or zwitterionic surfactant, relative to the total weight of the composition,
- b) at least one non-ionic surfactant, and
- c) at least one propellant.
