Question 1

What does Limonene. DN 029-032-01 do in a cosmetic formula?

Accepted Answer

This ingredient is primarily used as a fragrance component, bringing a citrus-like scent profile to perfumes, skin care, hair care, and cleansing products. It can also act as a light solvent for oily fragrance materials.

Question 2

Is Limonene. DN 029-032-01 clean?

Accepted Answer

From a clean beauty perspective, this ingredient is acceptable but flagged because it is a recognized fragrance allergen that requires label disclosure in some regions above very low thresholds. The main concern is oxidation during storage, which can create sensitizing byproducts, so fresh material, antioxidants, and air-tight packaging matter.

Question 3

Is Limonene. DN 029-032-01 sustainable?

Accepted Answer

This material is often sourced from citrus peel, a byproduct stream of juice processing, which is a favorable sourcing story when supply chains are well managed. It is readily biodegradable, but it is volatile and can contribute to fragrance-related VOC load during manufacture and use.

Question 4

Is Limonene. DN 029-032-01 COSMOS-approved?

Accepted Answer

It can be permitted under COSMOS-natural and COSMOS-organic standards when it comes from compliant natural fragrance sources, while fully synthetic routes are not aligned with certified natural positioning. Its Green Chemistry fit is strongest when upcycled from citrus processing and handled with oxidation control, with good biodegradability but some volatility tradeoffs.

Question 5

How does Limonene. DN 029-032-01 work chemically?

Accepted Answer

This molecule is a small cyclic monoterpene hydrocarbon with high volatility, low water solubility, and strong compatibility with oil phases and fragrance concentrates. Typical finished-product levels range from trace amounts to well below 1% in many leave-on products, and stability depends on limiting oxygen, light, and heat because autoxidation can form hydroperoxides.
