Sunscreen formulations are critical for protecting the skin from harmful UV radiation. However, maintaining the efficacy of sunscreens, especially during activities involving water or sweat, poses a significant challenge for formulators. This is where advanced ingredients like 1,2-Pentanediol (CAS 5343-92-0) come into play, offering enhanced water resistance and improved overall performance.

Understanding Water Resistance in Sunscreens

Water resistance in sunscreens refers to the ability of the product to maintain its SPF (Sun Protection Factor) protection after exposure to water. This is often achieved through the use of specific film-forming polymers and ingredients that can help anchor UV filters to the skin, preventing them from being washed away. Ingredients that can help create a more stable emulsion and improve adhesion are highly valued.

1,2-Pentanediol: A Key Enabler for Water-Resistant Formulations

1,2-Pentanediol, a multifunctional glycol, possesses properties that make it an excellent addition to sunscreen formulations aimed at achieving superior water resistance. Its chemical structure allows it to interact favorably with other formulation components, contributing to a more stable emulsion. This stability, in turn, helps to keep the UV filters in place on the skin, even when exposed to water. Beyond its water-resistance enhancing capabilities, 1,2-Pentanediol also provides excellent moisturizing and mildness, making it a valuable ingredient for daily wear sunscreens.
