#1Avobenzone
Avobenzone is the only chemical UV-protection component with a broad spectrum coverage. It can help to block both UVA I and UVA II rays. It's safe and it is allowed to use at a 3% concentration in the USA and a 5% concentration in the EU countries.
There is one problem: avobenzone loses efficiency when exposed to the sun. If you are outside, it loses 36% of its ability to block UV rays an hour after application. That's why it's recommended to reapply sunscreen every 2 hours.
#1Zinc Oxide
Zinc Oxide is a great physical sunscreen, meaning it deflects the UV rays. It’s the only natural mineral sun protector recommended by the FDA for babies. It’s good for sensitive skin because it’s less irritating than chemical sunscreens.
It has very nice spectrum protection. It helps to protect from UVA I, UVA II, and UVB and nowadays it’s the broadest range of sunscreen used in cosmetics. In other words, it’s brilliant in its league.
The negative side is that it can feel heavy on the skin. It can leave a slight whitish tint on the surface of the skin and some people may not like this. Keep in mind that it’s relatively easy to wash off, so it’s better to use water-resistant sunscreens if you are swimming.
#2Homosalate
#3Water
Water is a great solvent. It’s neutral and doesn’t provide any strong positive or negative effects. It just helps components to mix better and to transport active components.
#4Octocrylene
Octocrylene is an organic chemical sunscreen. It protects against UVA and UVB rays that can damage your skin or even lead to melanoma. It also stabilizes other sunscreen ingredients in a formulation and increases the water resistance of a product. It is approved by the FDA in concentrations of up to 10%. It’s not a very effective component on its own, that’s why manufacturers combine it with other chemical sunscreens.
Despite its effectiveness, there are some “cons” against the component. As with any other chemical sunscreen, it is absorbed and can be detected in blood. This doesn’t mean the component is harmful, but still… Octocrylene should also be used carefully by anyone who is breastfeeding because it can be found in breast milk.
Anyway, the component isn’t researched quite well despite its popularity. More studies are required to determine how safe the component is.

#4Isododecane
Isododecane is an emollient and a good base for colorants. Very often used in powders and shades because it spreads on the skin nicely. It also helps to soften the skin and helps to lower water loss making all the moisturizing components work better.
#5Cyclopentasiloxane
Cyclopentasiloxane is a fluid silicone. It’s non-greasy and doesn’t have any scent or color. It evaporates pretty fast which makes this ingredient essential when it comes to making products that have to dry quickly. It also gives a nice silky feeling when you apply the product to the skin and hair. It leaves a thin film that protects the skin after evaporation.
Cyclopentasiloxane is chemically neutral, meaning it doesn’t react with other components.
