Poly(N-acrylalkyleneimine) modified Organopolysiloxanes |
摘要 |
<p>Organopolysiloxanes composed of an organopolysiloxane segment and a poly(N-acylalkyleneimine) segment which is bonded to at least one silicone atom of said organopolysiloxane segment via an alkylene group containing heteroatom(s) and which consists of repeating units represented by formula (1): <CHEM> wherein R<1> represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms; and n is a number of 2 or 3; wherein the weight ratio of the organopolysiloxane segment (a) to the poly(N-acylalkyleneimine) segment (b) Ä(a)/(b)Ü is at least 5/95 and less than 40/60, and the weight-average molecular weight is from 10,000 to 500,000. These organopolysiloxanes are soluble or dispersible in water and can form a film with an excellent texture. Thus, they can be appropriately employed as additives for cosmetic products.</p> |
