Homosalate, also known by its acronym HMS, stands as a widely recognized and utilized organic compound in the field of personal care, specifically within sun protection products. Functioning primarily as an oil-soluble ultraviolet B (UV-B) filter, it plays a crucial role in shielding the skin from the harmful effects of sun exposure.

UV-B radiation is a significant contributor to sunburn and long-term skin damage. By absorbing UV-B rays, Homosalate helps to prevent these detrimental effects, making it a foundational ingredient in a variety of sunscreens and other sun-protective cosmetic preparations. Its effectiveness in the UV-B range makes it a valuable component in formulating broad-spectrum sunscreens when combined with filters that protect against UV-A radiation.

Chemically, Homosalate is an ester derived from salicylic acid and 3,3,5-trimethylcyclohexanol. It typically presents as a colorless to pale yellow liquid, possessing specific physical characteristics such as density and refractive index that are important for formulation chemists. Its oil-soluble nature ensures that it integrates well into the lipophilic phase of emulsions commonly found in creams, lotions, and oils.

Beyond its primary function as a UV-B absorber, Homosalate exhibits another advantageous property: it can act as an effective solvent for certain other solid UV filters. This characteristic is particularly useful in formulations where it is necessary to dissolve solid filters like Avobenzone (Butyl Methoxydibenzoylmethane) or Ethylhexyl Triazone, helping to create stable and clear sunscreen products. This solvent capability simplifies formulation processes and improves the compatibility of various ingredients within the final product.

Regulatory bodies around the world have assessed Homosalate for safety and effectiveness. Maximum permissible concentrations vary by region, reflecting different regulatory frameworks and evaluations. For instance, regulations in the European Union and Japan permit concentrations up to 10%, while in the USA and Australia, levels up to 15% are allowed in sunscreens. These varying limits underscore the importance of adhering to regional guidelines when formulating products for international markets.

Handling and storage recommendations for Homosalate typically involve keeping containers tightly closed, storing in a cool place, and ensuring the material remains dry to maintain its stability and efficacy over time. It is miscible with ethanol and common lipids, facilitating its incorporation into various cosmetic bases, though it does not mix with water.

As a key ingredient in the personal care industry, the availability and quality of Homosalate are critical for manufacturers of sun protection products. Sourcing high-quality Homosalate is paramount for ensuring product performance and compliance with regulatory standards. Companies seeking a reliable manufacturer or supplier of Homosalate (HMS) can find various options available globally. When looking to buy or purchase Homosalate, it is advisable to consider suppliers who can provide detailed specifications and regulatory documentation to ensure the material meets the required standards for cosmetic use. The price of Homosalate can vary based on factors such as purity, quantity, and market conditions.
