Description

EXAMPLES

Example 1

[0258] The following composition A was prepared from the ingredients detailed in the table below, in which all the amounts are indicated as weight percentages of active material (AM) relative to the total weight of the composition.

TABLE-US-00001 Content (weight Ingredients % of AM) OLETH-10 7.6 DECYL GLUCOSIDE 0.52 LAMBDA-CARRAGEENAN 0.95 GLYCEROL 0.95 BENZYL ALCOHOL 0.95 GLUCOSE 2.85 PRESERVATIVES qs ISOBUTANE/PROPANE/BUTANE MIXTURE 5 DEIONIZED WATER qs 100

[0259] Composition A above is clear, with a monophasic appearance, and has a turbidity of 24.4 NTU measured using a turbidimeter, model HI 88713-ISO from the company Hanna Instruments.

[0260] The monophasic appearance and the clarity of the composition are stable over time. In particular, after 2 months of storage at ambient temperature (25 C.), the appearance of the composition has not changed.

[0261] Composition A above was packaged in a pressurized aerosol device.

[0262] On spraying, a firm, creamy foam is obtained, which spreads easily on the head of hair and gives good styling and cosmetic properties, in particular with long-lasting fixing and a pleasant feel. The hair is soft, and has volume. The hairstyle obtained is natural, with no helmet effect.

Example 2

[0263] The following compositions were prepared from the ingredients detailed in the table below, in which all the amounts are indicated as weight percentages of active material (AM) relative to the total weight of the composition.

[0264] Composition A1 (invention) above is clear, with a monophasic appearance, this being the case even after 2 months of storage at ambient temperature (25).

[0265] The turbidity of composition A1 is 4.19 NTU, measured using a turbidimeter, model HI 88713-ISO from the company Hanna Instruments.

[0266] Compositions C1, C3 and C4 (outside the invention) each exhibit an opaque white precipitate in suspension in the composition, whether a few seconds after preparing these compositions or after 24 hours of storage at ambient temperature (25 C.).

[0267] Composition C2 (outside the invention) exhibits two visually distinct phases, the upper phase of which is opaque, whether a few seconds after preparing the composition or after 24 hours of storage at ambient temperature (25 C.).
