Description

EXAMPLE

[0084] A composition according to the invention was prepared from the ingredients indicated in the table below. The amounts are indicated as weight percentages of starting material in unmodified form relative to the total weight of the composition.

TABLE-US-00001 Kaolinite.sup.1 (powder) 26.90 Hydrophobic fumed silica treated with 11.92 hexamethyldisilazane.sup.2 (powder) Hydrophobic fumed silica surface-treated with 11.92 dimethylsilane (powder) Mica (powder with a particle size of from 5 to 11 m) 22.41 Talc 11.95 Magnesium stearate.sup.3 (powder) 2.00 Polyethylene glycol (8 EO) 5.55 Poly(dimethyldiallylammonium chloride) in water at 5.55 40% of AM, non-stabilized 2-Phenoxyethanol 1.00 Fragrance 0.30 1,2-Octanediol 0.50 AM: Active material .sup.1Kaolin Supreme from Imerys .sup.2Aerosil R812S - Evonik .sup.3Magnesium stearate - Starineries Dubois

[0085] This composition was prepared by: [0086] mixing the powders and the solid starting materials in a mixer equipped with paddles, a lump breaker and a jacket, so as to obtain a product that is as homogeneous as possible, [0087] incorporating the liquid starting materials, by spraying using a spraying nozzle, [0088] manual or automatic screening to make the powder more uniform and to break up any agglomerates before compacting, the screen used having a mesh size of 250 m, and [0089] compacting in metal dishes using an electric compactor, at a pressure expressed as force of between, for example, 500 and 1200 kg.

[0090] The powder thus compacted is applied onto the hair by finger or using a suitable applicator.

[0091] A soft, homogeneous, smooth feel is then obtained, along with a provision of volume and mass and lifting of the roots.
