English name: Single ended hydroxypropyl silicone oil
Other names: 3-(2-hydroxyethoxy)propyl terminated polydimethylsiloxane;
Hydroxypropyl silicone oil
CAS No.207308-30-3
Description:
It is a linear organic functional poly siloxane that can be used as the active component in suitable polymers due to the presence of terminated hydroxyl groups. It can be used in the synthesis of organosilicon-polyurethane/polyester block polymers.

Main Features:
It has a single terminated alcohol hydroxyl group and has the same reactivity as EO-terminated polyols.
It can be used to synthesize organosilica-polyurethane/polyester block polymers.
Improve water resistance of WPU.
Improve PU high and low temperature performance.
It can be used as powder cosmetic additive.
It can be used as spreading agent and compatible modifier of sunscreen.
Give cosmetics a unique touch and wettability.
Taking into account the silicone hand feel and anti-graffiti characteristics, it has better hand feel and anti-graffiti effect than the ordinary double-ended hydroxypropyl group.
Application:
Uses as the water-resistant and weather-resistant component of polyurethane, it participates in the curing or polymerization reaction to significantly improve the water resistance, high and low temperature performance, air permeability and compliance of the finished product. It takes into account the hand-feeling characteristics of silicone and anti-graffiti characteristics, and has better hand-feeling and anti-graffiti effect than ordinary double-ended hydroxy ethyl. As a cosmetic additive, it significantly improves the compatibility of components, gives the product a unique touch, improves the affinity with the skin, and wettability.
