Question 1

What does Octocrylene 5.0%Water do in a cosmetic formula?

Accepted Answer

This ingredient is an oil-soluble organic UV filter used mainly for UVB and short-UVA coverage in sunscreens and SPF cosmetics. It also helps stabilize less photostable UV filters in oil-phase sunscreen systems.

Question 2

Is Octocrylene 5.0%Water clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is often restricted or excluded because of sensitization concerns, endocrine-activity debate, and trace impurity issues that can increase with age and heat. It has more clean-standard friction than mineral UV filters and many newer-generation filters.

Question 3

Is Octocrylene 5.0%Water sustainable?

Accepted Answer

This material is synthetic and petrochemical-derived, with environmental concern tied to aquatic persistence and bioaccumulation potential. It is not considered readily biodegradable, so rinse-off and beach-use exposure are common points of scrutiny.

Question 4

Is Octocrylene 5.0%Water COSMOS-approved?

Accepted Answer

This ingredient is not permitted in COSMOS organic or COSMOS natural formulations as a sunscreen active. Its petrochemical origin, persistence profile, and limited biodegradability make it a weak fit with Green Chemistry priorities.

Question 5

How does Octocrylene 5.0%Water work chemically?

Accepted Answer

The molecule is an oil-soluble aromatic ester with a conjugated cyanoacrylate chromophore that absorbs mostly in the UVB and short-UVA range. Typical use levels are about 2 to 10%, with 10% as the maximum allowed in several major sunscreen regulations, and it is generally stable in anhydrous or emulsion oil phases but should be protected from excessive heat during storage.
