UV filters refer to substances that protect the skin and/or hair from UV radiation, listed in Annex VI of Cosmetics Regulation 1223/2009. According to their chemical composition, UV filters can be classified into organic filters, including avobenzone and octocrylene, and inorganic filters, such as zinc oxide and titanium dioxide. According to their mechanism of action, UV filters are divided into absorbers that absorb UV radiation and reflectors that scatter or reflect UV rays. "UV filter" on ECHEMl mainly supplies raw materials for the UV filter.

More Information

Sunscreen

Melanoma is one of the most lethal cancers. Excessive exposure of the skin to ultraviolet (UV) radiation is the primary factor leading to skin cancer. It is evident that the most effective preventive measure is the use of sunscreen products. Sunscreen products rely on UV filters.

UV filters are specifically or primarily designed to protect the skin and/or hair from the effects of certain UV radiation by absorbing, reflecting, or scattering UV radiation. There are two types of UV filters available for sunscreens. The most commonly used one is referred to as organic filter sunscreen agents, which absorb UV radiation and then convert it into radiation safer for human skin. The other type includes inorganic UV filters, capable of reflecting and scattering UV radiation, preventing it from harming the skin, and widely considered to be safe.

Frequently Asked Questions

What is a UV filter and how does it work?

A UV filter is a chemical compound or physical barrier used to absorb, reflect, or scatter ultraviolet (UV) radiation from the sun. In skincare and cosmetics, UV filters protect the skin by preventing UVA and UVB rays from penetrating the epidermis, thereby reducing the risk of sunburn, premature aging, and skin cancer. UV filters are categorized into organic (chemical) and inorganic (mineral) types, each with distinct mechanisms of action.

What are the differences between organic and inorganic UV filters?

Organic UV filters, such as avobenzone and oxybenzone, absorb UV radiation and convert it into a small amount of heat. In contrast, inorganic UV filters like zinc oxide and titanium dioxide sit on the skin’s surface and physically block or scatter UV rays. Organic filters tend to be more cosmetically elegant but may cause sensitivities in some individuals, while inorganic filters are generally gentler and offer broad-spectrum protection without significant skin absorption.

Are UV filters safe for daily use in skincare products?

Yes, UV filters approved by regulatory bodies such as the U.S. FDA, EU Commission, and other global health authorities are considered safe for daily use when formulated within established concentration limits. Extensive toxicological and photostability testing ensures their safety and efficacy. However, individuals with sensitive skin may prefer non-nano mineral UV filters like zinc oxide to minimize irritation or allergic reactions.

How do I choose the right UV filter for my cosmetic formulation?

When selecting a UV filter for cosmetic formulations, consider factors such as desired SPF level, UVA/UVB protection balance, product texture, stability under light and heat, and regulatory compliance in your target market. Broad-spectrum filters like Tinosorb S or zinc oxide are popular for offering high photostability and compatibility with various bases. Always verify regional regulations—some UV filters permitted in the EU may not be approved in the U.S., and vice versa.

What are common applications of UV filters beyond sunscreen?

UV filters are widely used beyond traditional sunscreens—in moisturizers, foundations, lip balms, hair care products, and even packaging materials. In plastics and coatings, UV filters prevent photodegradation and extend product lifespan. In cosmetics, they help maintain formula integrity and color stability by protecting active ingredients from UV-induced breakdown. Their inclusion in everyday personal care items supports cumulative sun protection and long-term skin health.
