BIS-ETHYLHEXYL HYDROXYDIMETHOXY BENZYLMALONATE

Description

Bis-ethylhexyl hydroxydimethoxy benzylmalonate is an advanced photostabilizer used in sunscreen and skincare formulations. This synthetic compound functions primarily to enhance the stability and efficacy of UV filters, particularly avobenzone, in broad-spectrum sunscreen products. Its molecular structure allows it to absorb and dissipate UV energy, preventing the degradation of other photoprotective ingredients.

The ingredient demonstrates excellent compatibility with various cosmetic formulations, including lotions, creams, and sprays. It is oil-soluble, making it ideal for incorporation into water-resistant sunscreen products. Bis-ethylhexyl hydroxydimethoxy benzylmalonate has been shown to significantly extend the photostability of sunscreen formulations, maintaining their SPF and UVA protection factors for longer periods of exposure to sunlight.

Clinical studies have indicated that this compound exhibits low skin penetration and minimal irritation potential, contributing to its safety profile in topical applications. Its use in sunscreens can lead to more effective and longer-lasting sun protection, potentially reducing the risk of UV-induced skin damage and photoaging. The ingredient is typically used at concentrations between 1% and 5% in finished products, depending on the formulation and desired level of photostabilization.
