HOMOSALATE

Last update on Jan 8, 2024
Homosalate is a chemical compound commonly used in cosmetics and sunscreens as an ultraviolet (UV) filter, offering protection against sun-induced skin damage. Apart from this, it enhances the overall stability of sunscreen formulations. It is versatile and popular for its light, non-greasy texture, making it a preferred choice in various skincare products. While effective in UVB protection, it is important to note that Homosalate primarily addresses shorter-wavelength UV rays, necessitating the combination with other sunscreen agents for broad-spectrum coverage against both UVA and UVB rays. Additionally, Homosalate also goes by the name homomenthylsalicylate and has the chemical formula C16H22O3.

What is HOMOSALATE used for?

Homosalate serves sunscreens and cosmetics primarily as a chemical UV filter. It absorbs the UV rays, specifically UVB rays, that are known to cause sunburn and contribute to sun damage. These harmful rays can also cause the skin to tan and sometimes lead to skin cancer. Homosalate is a stable ingredient that works its magic against UV rays for longer durations. Indirectly, it also acts as an anti-aging compound for the skin - maintaining its health and keeping it youthful. However, Homosalate is not strong enough to be used independently and is often combined with other ingredients to maximize protection.

Origin

Homosalate is an ester that is made by the esterification of 3,3,5-trimethylcyclohexanol and salicylic acid. The latter has the ability to absorb UV rays and protect the skin from damage. Homosalate appears as a clear, colorless to pale yellow liquid and has a slight minty odor. This ingredient is purified for use in the cosmetic industry.

Safety Profile

Homosalate is generally considered safe for use when applied topically. However, some concerns have been raised about its potential to penetrate the skin and disrupt hormone function, particularly when used in high concentrations. While regulatory bodies permit its use within specified limits, individuals with sensitive skin may choose alternative sunscreens. It is crucial to follow product guidelines, and those with specific health concerns should consult a healthcare professional. Homosalate should be avoided by pregnant women and babies. Additionally, Homosalate is a vegan and halal ingredient. It has a shelf life of 2-3 years.
