After cooling, distillation purification was performed under reduced pressure. From the 1H-NMR spectrum of the obtained product, the obtained product was a dimethylsiloxane methyl (undecyl glyceryl ether) siloxane copolymer having a C16 and C18 alkyl group at both ends (p = 23, q = 4) (63.0 g, yield; 95%).
The obtained copolymer is a random copolymer as follows in General formula (3).
R ¹ and R ⁹ = an alkyl group whose mode of carbon number is 18;
R ^{2 to} R ⁸ = methyl group,
Q = a linear alkylene group having 11 carbon atoms,
R ¹⁰ and R ¹¹ = hydrogen atom,
p (average value) = 23,
q (average value) = 4.0

Examples 1-7, Comparative Examples 1-3
Oily stick lipsticks with the composition shown in Table 1 were manufactured, smoothness during application, vividness of application color, glossiness during application, persistence of vividness of application film, durability of application film gloss and lipstick hardness. The retention rate of was evaluated. The results are also shown in Table 1.
