Description

The present invention relates to a cosmetic composition, in particular a capillary composition, comprising the combination of hollow or porous particles, of a thickening polymer and of a monoalcohol, and a process for using and using said composition and / or a composition. comprising said particles and said monoalcohol. Hair tends to lose some of its qualities under the action of factors such as natural regreasing, sweat, the elimination of dander, pollution or moisture in particular. The visual appearance and the feel of the hair can be degraded. Regreasing, for example, weighs down the hair, which then tends to pack. The hair may be more difficult to comb, and have a greasy shine or an unpleasant waxed touch. To combat these inconveniences, it is possible to use detergent compositions, for example shampoos, in order to eliminate soiling (sebum, sweat, pollution, etc.) or dandruff, and to relax the hair. The hair is then rinsed and dried. However, the beneficial effect of the shampoo fades and we find in a few days the problems described above. As a result, there is a tendency to increase the frequency of shampoos. Shampoos must be renewed regularly, for example after a few days or even after a few hours. However, shampoos based on large amounts of anionic surfactants can cause discomfort such as tingling of the scalp or in the eyes. Shampoos can also combine with surfactants, sebum absorbers to prolong the perception of cleanliness of hair. However, it has been found that the effectiveness of these products is still insufficient compared to consumer expectations. In fact, they do not make it possible to significantly reduce the frequency of washing of the hair, which frequency may differ according to the country or even according to the region concerned and which may range from one to two shampoos a day to one or two shampoos per day. week. Furthermore, the use of a shampoo requires a source of water, preferably hot or warm. To clean the hair faster and avoid wetting the hair, it has already been proposed to use shampoos called "dry". This technique involves depositing absorbent particles on the hair and then actively brushing the hair to remove the particles. But in general, the complete elimination of particles is very difficult to obtain. The results are not very satisfactory: the shine of the hair is weak and their touch is rough and crunchy.

To date, no cosmetic hair hygiene composition can significantly slow the regreasing of the hair. The object of the present invention is to propose cosmetic hair compositions that overcome these disadvantages. The subject of the invention is therefore a cosmetic composition comprising: hollow and / or porous particles; one or more monoalcohols comprising 2 to 6 carbon atoms, especially 2 to 4 carbon atoms; and one or more thickening polymers. The use of compositions according to the invention makes it possible to significantly reduce the regreasing of the hair and / or the scalp, and therefore the greasy appearance and the greasy feel of the hair and thus makes it possible to reduce the frequency of washing and drying. Space shampoos. The compositions according to the invention make it possible to preserve a perception of clean hair for a longer time than with a usual shampoo; for example, this perception of clean hair can be a week 20 for people usually washing their hair 2 to 3 times a week, and can be at least three days for people washing their hair usually everyday. In addition, the compositions according to the invention are easily distributed on the hair, from the tip to the root, and thus allow better removal of soils, on the whole of the hair. In the end, the hair has a natural touch, soft and silky, the hair is more delicate and shinier. The hair has a facility of shaping and lightness. In the present description, the term "at least one" is equivalent to the term "one or more" and may be substituted therefor.
