[0339] Composition Preparation Protocol

[0340] The phase A1 is heated to a temperature that allows all of the constituents to be melted (about 75°-80° C.) then the phase A2 is introduced into the phase A1 under Raynerie stirring, keeping the whole at 65° C.

[0341] The aqueous phase B is placed in Raynerie under stirring and heated to 70 so that all of the ingredients are melted, the temperature is then brought to 65° C. Preparation of the emulsion: still at 65° C., the phase Al+A2 is incorporated into B in the Raynerie and the whole is stirred for 10 minutes then the phase C is added (by increasing the speed if necessary). After 10 minutes the phase D is added and after 5 minutes the phase E is added. The composition is stirred again for 15 minutes.

[0342] Evaluation of the Compositions

[0343] The compositions of examples 1 and 2 comprise, as surfactants, mixtures of compounds comprising C20 and C22 fatty chains. For these compositions, the formulas obtained are compact and therefore have a satisfactory aspect while still allowing for a good application and a natural result.

[0344] The composition of example 3 comprises a C22 fatty alcohol. For this composition, the formula obtained is compact and therefore has a satisfactory aspect while still allowing for a good application and a natural result.

[0345] The composition of example 4 comprises a C18 surfactant and therefore does not contain any fatty acid or alcohol according to the invention. For this composition, the formula obtained is not compact but is rather soft and elastic.

[0346] It has therefore been shown that for a composition that does not contain fatty alcohol or acid according to the invention, namely an fatty alcohol or acid with a fatty chain comprising at least 20 carbon atoms, the formula obtained is not nomad as it is too liquid. In addition, taking the product on the finger or a sponge is not good because, as the product is too soft, the quantity of the product taken is excessive.
