Full-spectrum blocking of ultraviolet rays, the guardian of whitening—OMNISTAB ES7420

PHOTO ID:46792288

In the scorching summer, ultraviolet (UV) rays are intensely emitted. As a summer essential, sunscreen should possess characteristics such as high-efficiency protection, non-toxicity and safety, excellent UV and thermal stability, and good compatibility.

Based on their mechanism of action, sunscreens are categorized into three main types: Chemical Sunscreens, Physical Sunscreens, and Biological Sunscreens. Physical sunscreens primarily work by reflecting and scattering UV rays. Biological sunscreens themselves do not absorb UV rays but provide indirect protective effects. Chemical sunscreens function by absorbing UV radiation and converting it into heat, thereby reducing skin damage. These components can penetrate the stratum corneum, bind with skin cells, and form a protective layer that effectively blocks UV rays. Chemical sunscreens are typically lightweight in texture, easy to apply, and, due to their variety, large production volume, low cost, and easy availability, have become the predominant type of sunscreen on the market.

UV absorbers are the core of chemical sunscreens. Common UV absorbers on the market often only guarantee absorption in the UVB spectrum, neglecting the damage caused by UVA rays. While benzotriazole-class UV absorbers can cover both UVB and UVA ranges, some products are listed as Substances of Very High Concern (SVHC), posing significant safety risks and making them difficult to be the "ideal match" for sunscreens.

So, is there an ingredient that can be used in sunscreens, is safe and reliable, and also offers full-spectrum UV absorption? Absolutely! DELTACHEM introduces the OMNISTAB ES7420 product, fulfilling all your expectations for chemical sunscreens.

As a UV absorber, OMNISTAB ES7420 boasts a broad absorption wavelength range, offering absorption performance for both UVA and UVB, covering 320-400 nm. It does not contain a benzotriazole structure, ensuring safe use. Furthermore, the symmetrical benzene rings and hydroxyl groups in its structure grant it excellent light and thermal stability, making it highly suitable for sunscreen products.

Beyond its use in sunscreens, OMNISTAB ES7420 also finds wide application in optical films, coatings, adhesives, lenses, and other fields. In recent years, it has garnered significant attention, particularly for its applications in the textile industry, and its range of uses is continually expanding.
