Question 1

What does Tocopherol. May Contain : CI 77891 do in a cosmetic formula?

Accepted Answer

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

Question 2

Is Tocopherol. May Contain : CI 77891 clean?

Accepted Answer

From a clean-beauty perspective, it is generally well accepted and has low irritation potential at typical cosmetic use levels. The main quality questions are source, concentration, and whether an optional mineral colorant is present for appearance rather than function.

Question 3

Is Tocopherol. May Contain : CI 77891 sustainable?

Accepted Answer

This material is commonly sourced from vegetable oil processing, including soy, sunflower, or rapeseed streams, though synthetic versions also exist. It is oil-soluble and biodegradable, with a comparatively low persistence concern when used at cosmetic levels.

Question 4

Is Tocopherol. May Contain : CI 77891 COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic when it meets the standard’s sourcing and processing requirements. It aligns well with Green Chemistry when plant-derived, concentrated from existing oil-processing side streams, and used to protect formulas from oxidation.

Question 5

How does Tocopherol. May Contain : CI 77891 work chemically?

Accepted Answer

The molecule is a fat-soluble phenolic antioxidant with a ring-and-tail structure that donates hydrogen to lipid radicals and helps interrupt oxidation chains. Typical use is about 0.05 to 0.5 percent for formula protection, with best stability in the oil phase and in packaging that limits air and light exposure.
