• Improves the stability of other UV filters
• Globally approved in amounts from 5–10%
• Helps neutralize the sun-induced formation of oxygen radicals

Octisalate Description

Octisalate is a synthetic sunscreen ingredient that works primarily in the range of UVB light while offering a small amount of UVA protection. It is also known as octyl salicylate and ethylhexyl salicylate.

This globally approved sunscreen ingredient is used in concentrations up to 10%, with 5% being a typical amount when combined with other UV filters. Such combinations are necessary since octisalate, like homosalate, is not a very efficient UVB absorber and must be used with more efficient UVB absorbers (i.e. octocrylene and octinoxate) to achieve high SPF. In addition, octisalate doesn’t provide sufficient UVA protection on its own.

Octisalate has been deemed safe as used as used in cosmetics and is not considered an eye or skin irritant. Research has shown this UV filter can neutralize singlet oxygen, a type of skin-damaging free radical generated by exposure to UVB light.

This sunscreen active is one of several currently undergoing further safety testing under the purview of the United States Food and Drug Administration (FDA). This testing is to gain a better understanding of the systemic absorption, metabolism, and elimination of these sunscreen actives when small amounts enter the body via topical use. It’s important to know that the presence of this or other sunscreen actives in the body does not mean your health is at risk. It is anticipated that the additional testing being done will reaffirm the safety of these ingredients; however, those who remain concerned can choose sunscreens with mineral actives (titanium dioxide and zinc oxide) which are not included in the FDA’s new call for additional testing.
