Description

EXAMPLE

[0171] In the example that follows, all the amounts are indicated as weight percentages of product in unmodified form relative to the total weight of the composition.

[0172] The following compositions according to the invention are prepared starting from the compounds indicated in the tables below.

TABLE-US-00002 A DRY FLO PLUS by National Starch (86% 92.15 Aluminium Starch Octenylsuccinate) Calcium carbonate (D50 = 35 μm).sup.1 1.45 Hectorite modified with 2.00 distearyldimethylammonium chloride.sup.2 Isopropyl myristate 3.00 Starch-based fragrance capsules.sup.3 1.40 .sup.1Sold under the trade name Omyacare S60 by Omya .sup.2Sold under the trade name Bentone 38 by Elementis .sup.3Sold under the trade name Apple Blossom Caps by Firmenich

[0173] This composition A was introduced into a small bottle of salt-shaker type.

TABLE-US-00003 B DRY FLO PLUS by National Starch (86% 10.92 Aluminium Starch Octenylsuccinate) Calcium carbonate (D50 = 35 μm).sup.1 2.18 Hectorite modified with 0.28 distearyldimethylammonium chloride.sup.2 Isopropyl myristate 0.42 Starch-based fragrance capsules.sup.3 0.19 Isobutane 86.00 .sup.1Sold under the trade name Omyacare S60 by Omya .sup.2Sold under the trade name Bentone 38 by Elementis .sup.3Sold under the trade name Apple Blossom Caps by Firmenich

[0174] This composition B was introduced into an aerosol device. Said device is fitted with a valve conventionally used for aerosols. Composition A and composition B were applied to a greasy, dirty head of hair. The application is well tolerated by the scalp. A fresh feel is observed on application.

[0175] After drying, it is observed that the head of hair is visibly cleaner with little visible residues. Lifting of the roots is also observed, and also increased volume. In addition, an instant refreshing effect is observed, which lasts throughout the day. The fragrancing effect lasts throughout the day and is reinforced every time moisture appears.
