★What is Homosalate and what role does it play in sunscreen formulations?
Homosalate is an oil-soluble organic UVB filter widely used in sunscreen and daily sun care products. It primarily absorbs UVB radiation in the wavelength range responsible for sunburn and contributes significantly to SPF performance. In formulation design, Homosalate is often used as a foundational UVB absorber within multi-filter systems to help achieve target SPF levels while maintaining good skin feel.
★What are the key benefits of Homosalate in cosmetic formulations?
Homosalate offers several formulation advantages, including effective UVB absorption, good oil-phase compatibility, and the ability to enhance overall SPF performance when combined with other filters. It also contributes to improving the sensory profile of sunscreen products by supporting smoother texture and better spreadability.
★How does Homosalate protect the skin from UV damage?
Homosalate works by absorbing UVB radiation and converting it into lower-energy heat, reducing the amount of harmful radiation that reaches the skin. This helps prevent sunburn and reduces the risk of UV-induced skin damage, making it an essential component in sun protection formulations.
★Is Homosalate effective as a standalone UV filter?
Homosalate is not typically used alone, as it primarily covers UVB protection and does not provide sufficient UVA coverage. To achieve broad-spectrum protection, it is usually combined with other UV filters, including UVA absorbers, to meet regulatory requirements and consumer expectations.
★What types of products commonly include Homosalate?
Homosalate is widely used in sunscreen creams, lotions, sprays, and sticks, as well as in daily skincare products with SPF such as moisturizers and foundations. Its versatility allows it to be used in both facial and body care formulations.
★What is the current regulatory status in the EU?
Since January 1, 2025, Homosalate-containing products not meeting restrictions cannot be placed on EU market. Since July 1, 2025, such products cannot be sold in EU. SCCS recommends max 7.34% for face-only products.
★What is the regulatory status in China?
Homosalate is listed in IECIC but was revised under China's 2026 Cosmetic Safety Technical Specification . Updated restrictions take effect January 1, 2028. Check current maximum permitted concentrations before export.
★What is the regulatory status in the United States?
FDA has not classified Homosalate as GRASE (Generally Recognized as Safe and Effective) due to insufficient safety data. It remains permitted in sunscreens up to 15% while FDA awaits additional safety studies.
★What is the recommended usage concentration for Homosalate?
Typical usage ranges from 5% to 15% in sunscreen formulations. EU restrictions now significantly limit allowable concentrations versus the US 15% maximum. China's revised limits take effect 2028. Verify local regulations before formulating.
