Diethylaminohydroxybenzoylhexylbenzoate is a synthetic sunscreen agent that helps protect the skin from UVA rays with maximum absorption at 354 nm (the UVA range extends to 400 nm). Currently, it is not an FDA-approved sunscreen agent in the United States; however, it is an approved UV filter in many other markets including the EU, China, Australia and Japan with a maximum concentration of 10%.
Suppliers of this ingredient and research studies indicate that diethylaminohydroxybenzoylhexylbenzoate provides excellent photostability. It is considered superior to avobenzone (another popular UVA spectrum sunscreen agent) in this regard and can be used alone or in combination with other UV absorbers. However, it is important to know that avobenzone's stability disadvantage can be overcome by several methods, making it a very effective UVA absorber.
Diethylaminohydroxybenzoylhexylbenzoate is lipophilic, meaning it is soluble in oils/fats/lipids, which positively affects the affinity of this ingredient to the epidermis, as this skin layer contains natural lipids.
Because of its role in protecting the skin from harmful UVA rays that accelerate the signs of aging, diethylaminohydroxybenzoylhexylbenzoate can be considered an anti-aging ingredient. This type of radiation is present all day long and penetrates deep into the skin, where it causes a cascade of damage that leads to many signs of aging, such as coarse wrinkles and loss of firmness.
In raw material form, the appearance of diethylaminohydroxybenzoylhexylbenzoate is described as a white to light salmon colored granular powder. Due to its oil-soluble nature, diethylaminohydroxybenzoylhexylbenzoate must be incorporated into the oil phase of emulsions. https://www.paulaschoice.com/ingredient-dictionary/ingredient-diethylamino-hydroxybenzoyl-hexyl-benzoate.html?q=Diethylamino%20Hydroxybenzoyl%20Hexyl%20Benzoate&fdid=ingredients
