It is a UV filter widely used in sunscreens and personal care formulations. It is comprised of 98% Homosalate, a chemical compound that absorbs UVB radiation helping to protect skin from sun damage.

Its primary function is to act as a UVB filter, offering sun protection by absorbing harmful UV radiation. This helps prevent skin damage caused by prolonged sun exposure, such as burns and premature aging.

It provides protection primarily against UVB rays. To achieve broad-spectrum coverage (both UVA and UVB protection), it is recommended to combine it with other UV filters like Avobenzone.

It is ideal for sunscreens, daily moisturizers with SPF, lotions, creams, and other sun care products. It can also be used in cosmetics like foundations with added sun protection.

It is compatible with most oils and emulsifiers commonly used in personal care formulations. However, it is advisable to check the compatibility with other UV filters and antioxidants to ensure efficacy and stability.

It is oil-soluble and may contribute to a smooth, non-greasy feel in emulsions and anhydrous formulations, enhancing the overall sensory experience.

The inclusion of it in a formulation significantly increases its SPF rating, as it efficiently absorbs UVB radiation. The overall SPF will depend on its concentration and combination with other UV filters.

It is not highly photostable on its own. It is often combined with stabilizers or other UV filters like Octocrylene to maintain effectiveness during sun exposure.

Yes, it can be formulated with natural oils, but compatibility testing is advised to ensure it maintains efficacy and stability in combination with natural actives.

It is generally well-tolerated. However, it is recommended to perform dermatological testing, particularly for sensitive skin products, to assess potential irritant effects.
