Which ingredients are commonly found in physical sunscreen?

Physical sunscreen typically contains active mineral ingredients that sit on the skin's surface to block and scatter UV radiation. The most common ingredients in physical sunscreens are titanium dioxide and zinc oxide. Both of these compounds are effective at providing broad-spectrum UV protection by reflecting and refracting sunlight, while also being less likely to irritate the skin compared to chemical sunscreens.

In contrast, other options presented do not reflect the primary components of physical sunscreen. The first option lists chemical UV filters that are used in some sunscreens but do not classify as physical blockers. The third option mentions surfactants and emulsifiers, which are generally used to enhance the formulation and stability of various cosmetic products but are not the active ingredients for sun protection. Lastly, essential oils and fragrances are typically added for scent and sensory appeal rather than providing any UV protection and may even cause irritation for some individuals. Therefore, the correct choice emphasizes the fundamental properties of physical sunscreens through the use of minerals like titanium dioxide and zinc oxide.
