BELSIL ADM 1650 is a non-reactive aminofunctional polydimethylsiloxane with an average viscosity of 1000 mm2/s. BELSIL ADM 1650 improves wet and dry combing for damaged and natural hair and causes a soft and smooth hair feel. When used in acidic formulations, its amine group is protonated and a cationic polymer is obtained. This polymer readily coats the negatively charged surface, providing excellent conditioning properties. Recommended use levels of BELSIL ADM 1650 in formulations are 0,25 % to 3 %.
