Question 1

What does Oxacycloheptadec-10-en-2-one 28645-51-4 do in a cosmetic formula?

Accepted Answer

This ingredient is primarily a fragrance material, used to give a soft musk-like odor and improve scent longevity in fine fragrance, hair care, body care, and rinse-off products.

Question 2

Is Oxacycloheptadec-10-en-2-one 28645-51-4 clean?

Accepted Answer

From a clean-beauty perspective, it is generally viewed more favorably than older persistent musk families, with relatively low reported sensitization compared with many common fragrance allergens. It still sits inside the fragrance category, so acceptance often depends on full disclosure, IFRA compliance, and brand-specific restricted lists.

Question 3

Is Oxacycloheptadec-10-en-2-one 28645-51-4 sustainable?

Accepted Answer

This material may be isolated from botanical sources or made synthetically, so its sustainability profile depends heavily on feedstock and supplier documentation. It is generally considered more biodegradable and less environmentally persistent than many older synthetic musk materials.

Question 4

Is Oxacycloheptadec-10-en-2-one 28645-51-4 COSMOS-approved?

Accepted Answer

It can align with COSMOS-natural or COSMOS-organic formulas when supplied as a compliant natural fragrance material under COSMOS fragrance rules. A fully synthetic petrochemical grade would not have the same COSMOS alignment, although the molecule fits Green Chemistry better when sourced from renewable feedstocks and supported by biodegradability data.

Question 5

How does Oxacycloheptadec-10-en-2-one 28645-51-4 work chemically?

Accepted Answer

The molecule is an unsaturated macrocyclic lactone, a ring-shaped ester with one carbon-carbon double bond that contributes a substantive, low-threshold odor profile. It is typically used at trace to low fragrance levels in finished products, is compatible with most emulsions and anhydrous systems, and ester hydrolysis becomes more relevant under strongly acidic or alkaline conditions.
