[0092] Hereinafter, although the synthesis example and the cosmetics of this invention are shown, the Example and a comparative example are shown, and this invention is concretely demonstrated, this invention is not limited to the following example. In addition, "%" described below means "mass%" unless otherwise specified, and represents the mass% of each component when the whole mass of each example is 100%. The viscosity is a value at 25° C. measured with a Canon-Fenske viscometer.
Synthetic example (1
[0094] Add 150 g of 2-allylphenol and 0.04 g of 2-propanol 3% of chloroplatinic acid tetramethyldivinyldisiloxane complex to a glass flask equipped with a stirrer, a thermometer, and a reflux condenser The solution was heated to 80°C. 248 g of heptamethylhydrotrisiloxane was added dropwise with stirring, and aged at 100° C. for 3 hours. The obtained reactant was stripped under reduced pressure at 150° C. under nitrogen bubbling to remove unreacted raw materials to obtain an organopolysiloxane having the following structure and a viscosity of 24 mm 2 / s light brown transparent liquid.

Synthetic example (2
[0098] Add the 2-propanol 3% solution of the eugenol of 53g and the chloroplatinic acid tetramethyldivinyldisiloxane complex of 0.01g in the glass flask that is equipped with stirrer, thermometer, reflux condenser, be heated up to 80°C. 73 g of heptamethylhydrotrisiloxane was added dropwise with stirring, and aged at 100° C. for 3 hours. The obtained reactant was stripped under reduced pressure at 160° C. under nitrogen bubbling to remove unreacted raw materials to obtain an organopolysiloxane with the following structure and a viscosity of 19 mm 2 / s light brown transparent liquid.
