Description

New cosmetic compositions

The present invention relates to new cosmetic compositions and their use, in particular as shampoo or cleanser. The present invention also relates to a device comprising the novel compositions.

BACKGROUND OF THE INVENTION

Most personal hygiene products, such as shampoos or cleansers, are marketed in liquid form. These products mainly comprise water, sometimes up to 90% by mass relative to the total weight of the product. The presence of large quantities of water has a negative impact on several points, for example on the environment or on the requirements related to the transport of the product. Indeed, the high volume of packaging leads to a high cost of transport by the distributor and constraints for the consumer, for example during a trip.

Given the presence of water, cosmetic compositions in liquid form require preservatives, and have quantities of active substances in a reduced percentage. As a result, the consumer spends a large sum for few active substances.

In recent years, a few shampoos and cleansers in powder form have appeared on the market. However, most of these products contain synthetic, potentially irritating chemical ingredients and/or allergens. In addition, the diversity of hair and skin types means that the range of products available does not meet the specific needs of each consumer.

There is therefore a need to provide alternative compositions, comprising ingredients that are natural or of natural origin, non-allergenic, healthy, and devoid of preservatives, preferably having a protective activity for the skin flora.

One of the aims of the invention is to provide a new combination in powder form, comprising a prebiotic.

Another object of the invention is a novel cosmetic composition in powder form comprising a prebiotic.

A third object of the invention is to be able to use the new combination, or a composition comprising it, as a shampoo or cleanser.

A fourth object is to provide a device comprising a shampoo or cleanser in powder form, which is easy to use.

One of the aims is to provide a cosmetic composition devoid of preservatives.

One of the other aims is to provide a cosmetic composition in which more than 15% by mass relative to the total weight of the composition, in particular more than 17%, consists of constituents and ingredients having a beneficial property for the skin. .
