SODIUM SULFATE

TL;DR. This ingredient is mainly used as a filler, bulking agent, viscosity modifier, or ionic-strength adjuster in cleansers, bath products, powders, and some surfactant blends. It can also appear as a processing residue from surfactant manufacturing.

What does SODIUM SULFATE do in a cosmetic formula?

This ingredient is mainly used as a filler, bulking agent, viscosity modifier, or ionic-strength adjuster in cleansers, bath products, powders, and some surfactant blends. It can also appear as a processing residue from surfactant manufacturing.

Is SODIUM SULFATE clean?

From a DARE clean-standards lens, this ingredient is generally low concern, non-sensitizing, and not a common restricted-list issue. At high levels, it can make formulas feel drying or contribute to mild eye or skin sting, especially in rinse-off products.

Is SODIUM SULFATE sustainable?

This material is mineral-derived or made as an industrial byproduct, with abundant supply and no bioaccumulation expectation. It does not biodegrade in the organic-carbon sense, but it dissociates in water, and very large releases can add to dissolved-solids load in waterways.

Is SODIUM SULFATE COSMOS-approved?

It is permitted in COSMOS-natural and COSMOS-organic products when sourced and processed according to the standard’s mineral and inorganic ingredient rules. Its Green Chemistry fit is solid because it is simple, non-persistent as a polymer, and often available from low-complexity mineral or byproduct streams, although biodegradability is not the right metric for an inorganic salt.

How does SODIUM SULFATE work chemically?

This material is a small, fully ionized inorganic electrolyte composed of two alkali-metal cations and one divalent oxyanion, and it is highly water-soluble and stable across normal cosmetic pH ranges. It is usually present at low percentages as an ionic-strength adjuster, filler, or surfactant-process residue, while bath products and powders can use much higher levels as a bulk mineral salt.
