Product: Homosalate
Rchem Homosalate is a high-purity, oil-soluble chemical (organic) UV filter, presented as a clear, colorless to pale yellow liquid. This widely used and cost-effective ingredient is a primary absorber of UVB radiation, the spectrum of sunlight responsible for sunburn and direct DNA damage. Renowned for its excellent solubilizing properties and light skin feel, it is a foundational component in many sunscreen formulations, helping to achieve high Sun Protection Factor (SPF) values while improving the cosmetic elegance of the final product.

Frequently Asked Questions:
What is the primary role of Homosalate in a sunscreen formulation?
Its primary role is to function as a UVB filter and SPF booster. It is very effective at absorbing the burning rays of the sun, making it a fundamental building block for achieving high SPF values in a cost-effective manner.
Homosalate has a relatively narrow absorption peak primarily in the UVB range. To provide broad-spectrum protection (which requires coverage of both UVB and UVA rays), it must be combined with other filters that cover the UVA spectrum, such as Avobenzone or Zinc Oxide.
Why is Homosalate almost always used in combination with other UV filters?
Major regulatory bodies worldwide, including the FDA and the European Commission, have approved its use in sunscreens up to a specified concentration. However, like many chemical filters, it is subject to ongoing scientific review. Recent discussions, particularly in the EU, have led to a reduction in its maximum permitted concentration due to safety concerns regarding systemic absorption and potential endocrine-disrupting effects at high doses. It is considered safe for topical use at approved levels.
s Homosalate considered safe for use?
Beyond its UV absorption, it acts as an excellent solvent and plasticizer. It helps dissolve solid UV actives, prevents crystallization in the formula, and can improve the spreadability and texture of the final product, reducing whitening and tackiness.
How does Homosalate improve a sunscreen's formulation?
Store in a cool, dark place in a tightly sealed container. It is a liquid and is generally easy to handle and incorporate into the oil phase of an emulsion. Standard personal protective equipment (PPE) like gloves and safety glasses is recommended. Always refer to the Safety Data Sheet (SDS) for comprehensive handling and safety information.
