Usage

Description

Drometrizole Trisiloxane is a chemical compound that serves as a UV absorber and filter, playing a crucial role in the synthesis of UV light absorbers and filters for various applications, including polyester fibers and suncare formulations. It is specifically designed to provide protection against harmful UV radiation, particularly in the UVA spectrum.

Uses

Used in Textile Industry:
Drometrizole Trisiloxane is used as a UV absorber/UV filter for polyester fibers to enhance their resistance to sunlight degradation and extend their lifespan. This application helps maintain the color and strength of the fibers, ensuring the durability and longevity of the textiles.
Used in Suncare Formulations:
Drometrizole Trisiloxane is used as a UV absorber/UV filter in suncare products to provide protection against the harmful effects of UV radiation, particularly in the UVA spectrum. This application helps prevent skin damage, premature aging, and reduces the risk of skin cancer caused by excessive sun exposure.
