实验室测试显示,“矿物”防晒霜往往含有隐性化学的紫外线吸收器,对声称纯度提出了挑战。 Lab tests show "mineral" sunscreens often contain hidden chemical UV absorbers, challenging claims of purity.

科学试验显示,矿物和化学防晒霜主要是通过吸收紫外线辐射而起作用的,而不是像人们通常认为的那样反映这种辐射。 Scientific testing reveals that both mineral and chemical sunscreens primarily work by absorbing UV radiation, not reflecting it as commonly believed. 许多标有"仅含矿物质"的产品含有未公开的化学紫外线吸收剂,如基酸和乙烯基烯,它们可以改善质地,减少白色造,并增加SPF. Many products labeled "mineral-only" contain undisclosed chemical UV absorbers like butyloctyl salicylate and ethylhexyl methoxycrylene, which improve texture, reduce white cast, and boost SPF. 实验室对多种防晒霜的测试发现这些添加剂是“矿物质专用”配方,这挑战了明确区分这两种类型的设想。 Lab tests on multiple sunscreens found these additives in "mineral-only" formulations, challenging the idea of a clear distinction between the two types. 调查结果表明,高水平的SPF和方便用户的应用往往需要混合各种成分,引起对标签透明度和消费者对矿物防晒霜纯度和安全的误解的关切。 The findings suggest that high SPF and user-friendly application often require a blend of ingredients, raising concerns about labeling transparency and consumer misperceptions about mineral sunscreens' purity and safety.
