Homosalate

Homosalate is an organic compound used in some sunscreens to absorb ultraviolet (UV) rays. It is a salicylate, a type of chemical that is related to aspirin. Homosalate can absorb UVB rays, which are the type of UV rays that cause sunburn and contribute to skin cancer.

Chemical properties

Homosalate is a colorless to pale yellow liquid that is slightly soluble in water. It has a mild, characteristic odor. The chemical formula for homosalate is C16H22O3, and its molecular weight is 262.34 g/mol. It has a boiling point of 107-110 degrees Celsius and a melting point of -25 degrees Celsius.

Uses

The primary use of homosalate is in sunscreens and other skin care products where it acts as a UV filter. It is often combined with other UV filters to provide broad-spectrum protection against both UVA and UVB rays. Homosalate can also be found in some cosmetics and hair care products.

Safety

The Food and Drug Administration (FDA) has approved the use of homosalate in sunscreens at concentrations up to 15%. However, there is some concern about the potential for homosalate to disrupt hormones in the body. Some studies have suggested that homosalate can act as an endocrine disruptor, interfering with the body's hormone system. More research is needed to fully understand the potential health effects of homosalate.
