What are Oleosomes Doing in My Sunscreen?

Posted by on 7/3/2017

But what is Oleosome technology?

And why is it an ingredient in your sunscreen?

To understand micron-sized oleosomes, you might need a crash course in plant biology.

Oleosomes are organized structures in plant cells that have a phospholipid membrane, a protein coat, and are high in essential vitamin E.

They serve as reservoirs for plant oils, which are a source of energy.

Sunflower, canola, safflower and cottonseed are all examples of plant seeds with oleosomes that store triglycerides as future energy sources.

These spherical oleosomes have been discovered to be the perfect storehouses for sunscreen because their biochemical makeup is stable and will not break down quickly.

This allows sunscreen to be encapsulated for gradual-release delivery over an extended period of time.

And that is not the only benefit of oleosomes in sunscreen.

They also do double duty as an emulsifying agent, combining and maintaining the integrity of all of the ingredients in the sunscreen formula.

This is good news because too many sunscreen emulsifying agents have been known to interfere with sunscreen’s formulaic chemistry.

With Oleosome technology, less sunscreen actives and emulsifiers are needed, eliminating the irritation that can be found in some sunscreen formulas with high Sun Protection Factor’s (SPF).

SPF measures sunscreen protection from UVB rays, which cause sunburn and contribute to skin cancer.

Fewer sunscreen actives results in a formula that is sheer and lightweight. It perfect for sensitive skin, but has the same broad-spectrum protection as a traditional formula would.

Also, because of oleosomes delayed-release structure, the sunscreen active and nutrients stored inside are released gradually, extending protection, moisture and skin hydration.

A final plus: the vitamin E naturally contained in these plant oleosomes offer the antioxidant power of blocking free radicals.
