Question 1

What does Aurantium Dulcis  Oil do in a cosmetic formula?

Accepted Answer

This ingredient is used primarily as a fragrance ingredient, adding a bright volatile scent and helping mask base odors in formulas.

Question 2

Is Aurantium Dulcis  Oil clean?

Accepted Answer

From a clean-beauty perspective, it is acceptable but not neutral because it contains fragrance allergens, especially limonene, and oxidized terpene byproducts can increase sensitization potential. It commonly requires allergen labeling when present above regulatory thresholds.

Question 3

Is Aurantium Dulcis  Oil sustainable?

Accepted Answer

This ingredient is plant-derived and is commonly obtained by physical expression of fruit peel, often from a juice-industry byproduct stream. Its terpene-rich profile is generally biodegradable, although concentrated releases can create aquatic exposure concerns.

Question 4

Is Aurantium Dulcis  Oil COSMOS-approved?

Accepted Answer

It is generally permitted under COSMOS-natural and COSMOS-organic when produced by accepted physical extraction methods and when fragrance-allergen disclosure rules are met. It fits Green Chemistry better on renewable sourcing and biodegradability than on oxidation stability, since its unsaturated terpenes need careful storage and antioxidant support.

Question 5

How does Aurantium Dulcis  Oil work chemically?

Accepted Answer

This material is a volatile essential-oil mixture dominated by monoterpenes, often mostly d-limonene, with smaller amounts of other terpenes, alcohols, and aldehydes. It is typically used at low fragrance levels, often below 1% in leave-on products, and should be protected from air, heat, and light because oxidation can form sensitizing hydroperoxides.
