Question 1

What does Salvia Rosmarinus do in a cosmetic formula?

Accepted Answer

This ingredient is mainly used as a botanical antioxidant and aromatic skin or hair-conditioning additive. In oil-rich formulas, it can also help slow rancidity by supporting oxidative stability.

Question 2

Is Salvia Rosmarinus clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is generally accepted when properly extracted and quality controlled. The main caveat is sensitization potential when it is used as a volatile aromatic material, especially as oxidation byproducts build over time.

Question 3

Is Salvia Rosmarinus sustainable?

Accepted Answer

This ingredient is plant-derived and generally biodegradable, with a renewable sourcing profile. Sustainability depends on farming practices, solvent choice, and traceability of the botanical supply chain.

Question 4

Is Salvia Rosmarinus COSMOS-approved?

Accepted Answer

This ingredient can align with COSMOS-natural and COSMOS-organic when sourced and processed through approved physical or permitted extraction methods. It fits Green Chemistry reasonably well when renewable feedstock, low-residue extraction, and biodegradable profiles are prioritized.

Question 5

How does Salvia Rosmarinus work chemically?

Accepted Answer

This material is a complex botanical mixture that may include phenolic antioxidants, caffeic-acid derivatives, and volatile terpenes depending on plant part and extraction method. It is typically used at low levels, with aromatic forms often below 1%, and it should be protected from heat, light, and air to limit oxidation.
