Question 1

What does Sodium Tocopheryl Phosphate do in a cosmetic formula?

Accepted Answer

This ingredient is a water-compatible antioxidant and skin-conditioning active. It is used to support barrier and calming claims while fitting aqueous phases more easily than oil-soluble antioxidant esters.

Question 2

Is Sodium Tocopheryl Phosphate clean?

Accepted Answer

It generally has a clean-standard profile with low irritation potential and little restricted-list friction. The main review point is documentation around synthesis, residual solvents, catalysts, and purity.

Question 3

Is Sodium Tocopheryl Phosphate sustainable?

Accepted Answer

This material is typically made by chemical modification of an antioxidant precursor that may be plant-derived or synthetic, combined with mineral-derived it and sodium. It is not known as a persistence or bioaccumulation concern, but its sustainability profile depends on feedstock origin and processing controls.

Question 4

Is Sodium Tocopheryl Phosphate COSMOS-approved?

Accepted Answer

This ingredient is not a simple COSMOS-organic staple because it is a chemically modified antioxidant salt, so certification depends on raw-material origin, allowed processing, and supplier documentation. From a Green Chemistry view, it is a mixed fit, with useful low-dose performance and likely degradability, balanced against extra derivatization steps.

Question 5

How does Sodium Tocopheryl Phosphate work chemically?

Accepted Answer

The molecule is an ionic it ester built on a chromanol antioxidant core, which improves water dispersibility and oxidative stability versus the non-phosphorylated parent structure. It is commonly used around 0.05% to 1%, with some active formulas higher, and it is generally best handled in neutral to mildly acidic or mildly alkaline aqueous systems rather than strong acid or base conditions.
