Definitions
- Powdery composition useful for the preparation of cosmetic whitening compositions
- the present invention relates to a powdery composition useful for the preparation of cosmetic compositions having a whitening effect.
- a whitening effect is then sought not only during the application of the cosmetic composition, but also over time for the whitening effect to occur in the longer term.
- whitening and / or brightening agents have been developed and introduced into cosmetic compositions.
- Cosmetic compositions having a whitening or brightening effect are for example described in the EP applications
- Bleaching agents are often not very stable because they degrade by heat and / or by oxidation, especially in an aqueous medium.
- the method for preparing a cosmetic composition typically comprises mixing the various constituents of the cosmetic composition. This method is facilitated when "all-in-one" products comprising several of the constituents of the cosmetic composition can be used in place of the constituents taken alone.
- the process comprises fewer steps, involves fewer starting materials, and the sometimes expensive component losses that may occur during the separate introduction of each component can be minimized.
- the invention relates to a powdery composition consisting of:
- an additive selected from vitamin B3, vitamin E, a ginseng extract, a red algae extract, a brown algae extract and mixtures thereof, and
- This powdery composition is adapted to be introduced into a cosmetic composition.
- the inventors have discovered that a cosmetic composition comprising this powdery composition has a whitening effect not only during the application of the cosmetic composition to the skin, but also a whitening effect prolonged in time when the cosmetic composition is applied daily, in particular over a period of at least 9 days.
- this prolonged effect over time would be due to the release of the whitening agent and / or the lightening agent from the pulverulent composition, this release being able especially to take place during the preparation of the cosmetic composition, or during the application of the cosmetic composition.
- the use of whitening agents is limited by the fact that these agents are often unstable.
- the whitening agent and / or the lightening agent of the pulverulent composition degrade less than the same whitening agents and / or free lightening agents, because they are encapsulated in the encapsulating agent of the powdery composition.
- the pulverulent composition can be stored before it is introduced into a cosmetic composition without these agents being degraded.

- the composition comprises from 80% to 97% by weight of pigment (s) relative to the total weight of the powder composition.
- the pulverulent composition according to the invention comprises one or more bleaching agents.
- a whitening agent is a chemical compound, synthetic or natural, which makes it possible to have a depigmenting effect on the skin.
- Two methods are usually used to highlight this depigmenting effect: either by quantifying the level of melanin in the epidermis, or by using the CIE Lab L * a * b * method to evaluate the color of the epidermis (the L * parameter indicating the clarity and the parameters a * and b * indicating the direction of the colors), for example by applying the bleaching agents on reconstituted pigmented human skin in vitro of the MelanoDerm® (MatTek) type.
