Monophasic appearance cosmetic hair composition comprising a particular nonionic surfactant

Abstract

The present invention relates to a cosmetic composition having a monophasic appearance, comprising at least one particular non-ionic surfactant, water and at least one propellant. The invention also relates to an aerosol device and also to a process for styling keratin fibres using such a composition.

Description

EXAMPLES

Example 1

(1) 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.

(2) 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

(3) 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.

(4) 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.

(5) Composition A above was packaged in a pressurized aerosol device.

(6) 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.
