Homosalate is used as a sunscreen, which filters ultraviolet rays and protects the skin from sun damage.
Homosalate is an organic chemical compound used primarily as a UVB filter in sunscreens and cosmetics. It absorbs specific ultraviolet rays (295-315 nm) that cause sunburn.
Its main use is as an active ingredient in chemical (organic) sunscreen lotions, sprays, and daily moisturizers with SPF. It is valued for its stability and light, non-greasy feel on the skin. Homosalate is often combined with other filters to achieve broad-spectrum UVA/UVB protection.
While approved globally (typically up to 10% concentration), its safety is periodically reviewed due to potential endocrine-disrupting properties and environmental concerns regarding coral reefs. It remains a common ingredient in many commercial sun care products.

Homosalate is an organic compound used primarily as a chemical UV filter in sunscreens and cosmetic products. It is a salicylate ester that effectively absorbs UVB radiation (wavelengths 295–315 nm), which is responsible for sunburn.
Sunscreens & Sun Care Products: A common active ingredient in chemical (organic) sunscreens, lotions, and sprays to protect skin from UVB damage.
Broad-Spectrum Formulations: Often combined with other UV filters (like avobenzone for UVA) to provide broader protection.
Cosmetics & Daily Wear: Found in moisturizers, lip balms, and foundations with SPF for daily UV protection.
Stability & Feel: Valued for its lightweight, non-greasy texture and stability in formulations.
It is widely approved in many countries (e.g., US, EU, Australia) within concentration limits (typically up to 10-15%).
Some health and environmental studies have raised questions about potential endocrine disruption and coral reef toxicity, leading to regulatory scrutiny and calls for further research.
Generally considered safe for topical use by major regulators when used as directed.
In short, homosalate is a common UVB-filtering sunscreen agent prized for its cosmetic elegance and efficacy in preventing sunburn.
Homosalate is a chemical uVB absorber.
