Chemical Compounds In Sunscreen

Additionally you may notice on some sunscreen labels the molecule ethylhexyl methoxycrylene.

Chemical compounds in sunscreen. How does sunscreen work. Sunscreen lotions vary enormously with their active ingredients. P aminobenzoic acid paba up to 15. The two inorganic compounds used are titanium dioxide and zinc oxide.

Peredo says to think of chemical sunscreen like a sponge. Avobenzone up to 3. In contrast chemical sunscreens absorb the sun s rays convert the rays into heat and release them into the skin the dermatologist explains. Dioxybenzone up to 3.

It absorbs the sun s rays before they can harm the skin chemical formulas consist of organic carbon based compounds like. Avobenzone oxybenzone octocrylene homosalate octisalate and octinoxate. These compounds are often described as merely providing a physical reflective barrier to uv light but in fact they can absorb the uv radiation and dissipate it harmlessly. The following list of active chemical compounds found in sunscreen formulas are approved by fda legislation.

Cinoxate up to 3. Methyl anthranilate up to 5. Titanium dioxide is often a primary ingredient in sunscreen because it works well as a uv filtering ingredient. The first sunscreens containing only these chemicals would have left a visible white layer on the skin.

It helps stabilize avobenzone even in the presence of octinoxate and provides us with longer lasting. Sunscreens also contain carbon containing molecules that absorb light such as oxybenzone octinoxate octisalate and avobenzone. Octocrylene up to 10. In response the fda redid the study this time including six active ingredients in chemical sunscreens.
