Question 1

What does Linalool +/- : Ci 77891 do in a cosmetic formula?

Accepted Answer

This ingredient is primarily used as a fragrance component, adding a floral, fresh scent note. The optional colorant notation means a formula may also contain a mineral pigment for whiteness, opacity, or shade adjustment.

Question 2

Is Linalool +/- : Ci 77891 clean?

Accepted Answer

This ingredient is an EU-listed fragrance allergen, so brands must disclose it above set thresholds in leave-on and rinse-off products. It is generally acceptable in clean-beauty frameworks, but oxidized residues can be more sensitizing, which creates some clean-standard friction.

Question 3

Is Linalool +/- : Ci 77891 sustainable?

Accepted Answer

This ingredient can be sourced from botanical essential oils or made synthetically, so its sustainability profile depends on feedstock and supplier controls. It is expected to biodegrade, while the optional mineral pigment is inorganic and persistent but not bioaccumulative in the usual cosmetic-use context.

Question 4

Is Linalool +/- : Ci 77891 COSMOS-approved?

Accepted Answer

It can align with COSMOS when derived from natural aromatic raw materials and used within compliant fragrance rules, while synthetic versions may not qualify for COSMOS-organic or COSMOS-natural certification. The optional mineral pigment is generally permitted under COSMOS when it meets purity and particle-size requirements.

Question 5

How does Linalool +/- : Ci 77891 work chemically?

Accepted Answer

The molecule is a small unsaturated terpene alcohol with volatility, odor impact at low levels, and susceptibility to air oxidation. In finished products it is usually present as a minor fragrance constituent, and formulas benefit from antioxidant support, limited air exposure, and appropriate packaging to manage oxidation.
