Question 1

What does TOCOPHEROL. MAY CONTAIN/PEUT CONTENIR: CI 77163 do in a cosmetic formula?

Accepted Answer

This ingredient is primarily an oil-phase antioxidant used to slow rancidity in oils, butters, and fragrance components. It can also support skin-conditioning claims in leave-on products.

Question 2

Is TOCOPHEROL. MAY CONTAIN/PEUT CONTENIR: CI 77163 clean?

Accepted Answer

It is generally well accepted in clean-beauty frameworks, with low irritation potential at typical cosmetic levels. Watchouts are mainly quality-related, such as oxidation state, carrier oil, or the presence of optional mineral colorant residues rather than the molecule itself.

Question 3

Is TOCOPHEROL. MAY CONTAIN/PEUT CONTENIR: CI 77163 sustainable?

Accepted Answer

This material is commonly sourced from vegetable oil refining streams, especially soy, sunflower, or rapeseed, though synthetic versions also exist. It is readily biodegradable and does not raise persistence or bioaccumulation concerns in normal cosmetic use.

Question 4

Is TOCOPHEROL. MAY CONTAIN/PEUT CONTENIR: CI 77163 COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic when the grade and processing route meet the standard’s requirements. It aligns well with Green Chemistry when plant-derived and used as a stabilizer that protects oils from oxidation and helps reduce formula waste.

Question 5

How does TOCOPHEROL. MAY CONTAIN/PEUT CONTENIR: CI 77163 work chemically?

Accepted Answer

The molecule is a lipid-soluble phenolic antioxidant with a chromanol ring that donates hydrogen to lipid radicals, plus a hydrophobic tail that keeps it in the oil phase. Typical use levels are about 0.05% to 1%, with best performance in anhydrous or oil-rich systems and better stability when protected from heat, light, and air.
