TL;DR. This ingredient is primarily used as an oil-phase antioxidant, helping slow rancidity and color or odor changes in oils, butters, and lipophilic actives.
What does Tocopherol. [+/- Ci 77491 do in a cosmetic formula?
This ingredient is primarily used as an oil-phase antioxidant, helping slow rancidity and color or odor changes in oils, butters, and lipophilic actives.
Is Tocopherol. [+/- Ci 77491 clean?
It is broadly accepted in clean-beauty frameworks and is generally well tolerated at typical cosmetic levels. Sensitivity is uncommon, though very high levels can feel heavy or be less comfortable for reactive skin.
Is Tocopherol. [+/- Ci 77491 sustainable?
This material is commonly sourced from vegetable oil streams such as soy, sunflower, or rapeseed, so its sustainability profile depends on agricultural practices and traceability. It is biodegradable and used at low levels, which supports a relatively light environmental footprint.
Is Tocopherol. [+/- Ci 77491 COSMOS-approved?
It is permitted under COSMOS natural and organic standards when the source and processing route meet the standard’s requirements. It fits Green Chemistry well when plant-derived, with renewable feedstocks, low use levels, and a preservative-support role that can reduce formula waste.
How does Tocopherol. [+/- Ci 77491 work chemically?
The molecule is an oil-soluble phenolic antioxidant with a chromanol ring and hydrophobic side chain, allowing it to donate hydrogen to lipid radicals and slow oxidative chain reactions. Typical use is about 0.05% to 1% in the oil phase, with best stability when protected from excess heat, light, and air.
