Question 1

What does Rosmarinus Officinalis  Leaf Co2 Extract do in a cosmetic formula?

Accepted Answer

This ingredient is primarily used as a botanical antioxidant, helping slow oxidation in oils, butters, and fragrance components. It can also contribute light skin-conditioning and aromatic effects depending on the extract profile.

Question 2

Is Rosmarinus Officinalis  Leaf Co2 Extract clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is generally well accepted because it is plant-derived and typically made without high-residue solvents. Its main caveat is the natural terpene fraction, which can matter for fragrance-allergen labeling and sensitive-skin positioning.

Question 3

Is Rosmarinus Officinalis  Leaf Co2 Extract sustainable?

Accepted Answer

This material comes from renewable plant leaves, and supercritical carbon dioxide extraction is a relatively clean process because the solvent can be recovered and reused. Its footprint depends mostly on agricultural practices, regional sourcing, and extract concentration.

Question 4

Is Rosmarinus Officinalis  Leaf Co2 Extract COSMOS-approved?

Accepted Answer

It is generally permitted under COSMOS-natural and COSMOS-organic when sourced from approved plant material and processed with permitted physical extraction methods. It fits Green Chemistry principles reasonably well through renewable feedstock, recyclable extraction solvent, and good biodegradability.

Question 5

How does Rosmarinus Officinalis  Leaf Co2 Extract work chemically?

Accepted Answer

The molecule profile is a complex mix of lipophilic phenolic diterpenes, flavonoids, and volatile terpenes, with antioxidant activity mainly tied to hydrogen-donating phenolic structures. Typical use is low, often around 0.02% to 0.5% in anhydrous or emulsion systems, and it should be protected from excess heat, light, and metal-catalyzed oxidation.
