The present invention is a urea group-containing organopolysiloxane represented by the following formula (1). [Wherein, R 1 is —R 5 —NHCONH 2 (R 5 is a divalent hydrocarbon group), and R 2 is a hydrogen atom, a hydroxy group, an alkoxy group, an alkyl group, a fluoroalkyl group, an aryl group, Or an aralkyl group, R 3 is R 1 or R 2 , R 4 is an organopolysiloxane segment represented by the following formula (2) (Q is an oxygen atom or a divalent hydrocarbon group The urea group-containing organopolysiloxane represented by the formula (1) has one or more R 1 in the molecule, and when c is 0, a + d + f + h + i is 1 or more. )] This provides a urea group-containing organopolysiloxane which can obtain a cosmetic having excellent cosmetic persistence while maintaining a light feel and good elongation, and a method for producing the same, and a cosmetic comprising the same. Be done. |
