Question 1

What does Diethylamino Hydroxybenzoyl Hexyl Benzoate do in a cosmetic formula?

Accepted Answer

This ingredient is an oil-soluble UV filter used to absorb UVA radiation, especially long UVA, in sunscreen and SPF-containing skin care. It is valued in formulas for broad-spectrum support and strong photostability.

Question 2

Is Diethylamino Hydroxybenzoyl Hexyl Benzoate clean?

Accepted Answer

From a clean-beauty perspective, it has friction because it is a synthetic organic UV filter and is not approved as an OTC sunscreen active in the U.S. It is generally considered low-irritation and low-sensitization, but some clean standards restrict broad categories of synthetic sunscreen actives.

Question 3

Is Diethylamino Hydroxybenzoyl Hexyl Benzoate sustainable?

Accepted Answer

This compound is synthetically made from petrochemical-derived aromatic building blocks and is highly lipophilic, so it is not a strong Green Chemistry fit. Low water solubility and limited biodegradation data create environmental-persistence questions.

Question 4

Is Diethylamino Hydroxybenzoyl Hexyl Benzoate COSMOS-approved?

Accepted Answer

It is not permitted under COSMOS-natural or COSMOS-organic standards, which favor mineral UV filters under defined conditions. From a Green Chemistry view, its synthetic aromatic structure, nonrenewable feedstock profile, and limited biodegradability weigh against it despite high photostability and use-efficiency.

Question 5

How does Diethylamino Hydroxybenzoyl Hexyl Benzoate work chemically?

Accepted Answer

The molecule is an oil-soluble aromatic ester with a it chromophore that absorbs mainly in the UVA range, with peak absorption around 354 nm and high photostability. In regions where allowed, it is commonly used up to 10% in sunscreen products, needs an oil phase or suitable solubilizers, and is typically paired with UVB filters for broad-spectrum coverage.
