Water-in-Oil TiO2 Sunscreen Lotion SPF 50

Using Titanium Dioxide as its only UV filter, this water-in-oil sunscreen lotion provides broad spectrum performance SPF 50. The formula was subjected to in vitro analysis and delivered SPF ~55, PFA (PPD) ~14 (PA+++) performance with critical wavelength 381nm.
It’s not surprising that more sun care formulations are turning to mineral UV filters like titanium dioxide (TiO2). These minerals are more natural alternative ingredients to traditional chemical sunscreens that provide broad-spectrum protection. TiO2 is most often used for UVB protection (290–320nm), but also provides significant UVA (320–400nm) protection.
As one of Hallstar’s newest innovations in mineral dispersions, HallBrite® EZ-FLO TDX features a proprietary and patented coating system that eliminates agglomeration and create a smooth lotion consistency while also outperforming the competition on whiteness reduction. But it also maintains safe, high-performing broad-spectrum protection without the synthetic sunscreens many consumers want to avoid (though the dispersions also work well with Avobenzone). The inclusion of HallBrite® BHB in HallBrite® EZ-FLO TDX aids wetting and dispersion of the Titanium Dioxide and contributes to an enhanced product feel. Finally, with the addition of Hallstar’s industry-leading SolaStay® S1, the most powerful photostabilizer on the market, this innovative mineral dispersion promotes exceptional stability. It’s a triple win for beauty and personal care companies: efficacy, aesthetics and natural ingredients.
