CAS No. 129119-77-3 is a polyether modified polysiloxane surfactant that is used as a hydrophilic surfactant in various industrial applications. This surfactant is especially useful in applications where hydrophilic properties are desired, such as in formulations of water-based adhesives, coatings and paints.
The polyether modified polysiloxane surfactant is a full-fledged nonionic surfactant. It is composed of two components, an isocyanate and a polyether. The isocyanate end of the molecule has hydrophobic (water repelling) properties, while the polyether end has hydrophilic (water attracting) properties. This allows the surfactant to interact with both water and oil, enabling it to act as an emulsifier, wetting agent and dispersant.
The polyether modified polysiloxane surfactant is highly soluble in water and has good compatibility with other surfactants. It is a colorless and odorless liquid that can be used in a variety of industrial applications. It is used in water-based coatings and paints as an emulsifier and dispersant, as well as in adhesives to improve adhesion and reduce foaming. It is also used as a leveling agent in printing inks and as an antifoam agent in aqueous systems.
In addition to its industrial applications, the polyether modified polysiloxane surfactant is also used as an ingredient in household and personal care products. It is commonly used in shampoos, body washes, bubble baths and other cleansing products, as well as in skin and hair conditioners. Its hydrophilic properties make it especially helpful in improving the spreadability and wetting of these products.
CAS No. 129119-77-3 is a versatile and effective surfactant that can be used in a wide range of industrial and consumer products. Its hydrophilic properties make it an ideal choice for water-based formulations, while its compatibility with other surfactants and its odorless, colorless nature make it a great all-around choice for many applications.
