EXAMPLES 11 TO 13

Preparation of the MQTpr Siloxane Resins

(79) The following resins are used:

(80) MQ resin=an MQ resin of formula M.sup.0.43Q.sup.0.57 and of Mn=3230 dissolved in xylene to a proportion of 70.8% by weight of solids. The MQ resin was manufactured according to the techniques described by Daudt in patent U.S. Pat. No. 2,676,182.

(81) T Propyl resin=a propyl silsesquioxane resin at 74.8% by weight in toluene. The propyl silsesquioxane resin was obtained by hydrolysis of propyltrichlorosilane.

(82) Preparation of the MQT.sup.Pr resins

(83) An MQ resin, a T propyl resin, xylene and 1M KOH in water in the proportions presented in Table 1 are introduced into a 3-necked flask equipped with a stirrer, a temperature probe and Dean-Stark apparatus mounted with a condenser. Xylene is pre-introduced into the Dean-Stark apparatus so as to ensure maintenance of a level of solids of 50% in the reactor. The mixture in the reactor is refluxed (between 100 and 140° C.) for at least 3 hours. Any water formed in the reaction mixture is continuously removed and trapped in the form of an azeotrope in the Dean-Stark apparatus. After refluxing for 3 hours, the water is removed from the apparatus and heating is continued for a further 30 minutes. After cooling the mixture, an excess of acetic acid is added to neutralize the KOH in the mixture. The mixture is then filtered to remove the salts formed, by passing it through a filter under pressure. Solvent exchange is performed by heating the mixture in a rotary evaporator under vacuum. After removing the majority of the xylene, decamethylcyclopentasiloxane (or isododecane) is added while continuing to remove any residual aromatic solvent. The structures of the resulting siloxane resins are characterized by .sup.29Si NMR spectroscopy and GPC, and the results are summarized in Table 2 below.

(88) Preparation Protocol

(89) 1) The aqueous dispersion of ethylcellulose is mixed with the nonvolatile polar oil with stirring, and the mixture is heated for 1 to 2 hours at 55° C.

(90) 2) The surfactant is added and the mixture is stirred at 55° C. until homogeneous.

(91) 3) The silicone resin is dispersed in the Polyphenyltrimethylsiloxy dimethylsiloxane (Wacker-Belsil PDM 1000 from Wacker) (Example 11) or in the Dimethicone (Wacker-Belsil DM 350 from Wacker) (Examples 12 and 13) at room temperature.

(92) 4) The mixture thus obtained is then added to the mixture containing the ethylcellulose, with continued stirring.

(93) 5) The dyes/pigments predissolved in water are then added.

(94) 6) Finally, the alcohol and the phenoxyethanol are added with stirring.

(95) Evaluation of the Formulas

(96) The tacky aspect, the aspect of the composition, the aspect of the deposit, and the gloss properties of the deposit were evaluated for each of the formulas thus obtained, according to the protocol described in Examples 7 and 8.

(97) Result

(98) A fluid, homogeneous mixture is obtained for the compositions of Examples 11, 12 and 13.

(99) The compositions of Examples 11, 12 and 13 are applied to the lips. They are comfortable on application (easy to apply and glide on application) and the deposits obtained are not tacky.

(100) For each of the compositions of Examples 11, 12 and 13, the makeup deposits obtained are homogeneous, thin and light, have very good gloss and gloss remanence (especially over 1 hour) on the lips, and also a satisfactory wear property of the color.
