Question 1

What does Sodium Chloride[1][3][4] do in a cosmetic formula?

Accepted Answer

This ingredient is mainly used as a viscosity modifier in surfactant cleansers, helping thicken shampoos, body washes, and hand washes. It can also adjust ionic strength and support rinse-off texture or soaking formats.

Question 2

Is Sodium Chloride[1][3][4] clean?

Accepted Answer

This ingredient is broadly accepted in clean-beauty standards and has low sensitization concern. At higher levels, it can feel drying or sting compromised skin and eyes, so use level and product type matter.

Question 3

Is Sodium Chloride[1][3][4] sustainable?

Accepted Answer

This material is typically sourced from seawater, brine, or mineral deposits, with a relatively simple supply chain. Biodegradation is not applicable because it is inorganic, but it dissolves readily in water and does not present persistence concerns in normal cosmetic use.

Question 4

Is Sodium Chloride[1][3][4] COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic frameworks when sourced and processed according to standard requirements. Its Green Chemistry profile is strong on simplicity, low transformation needs, and water compatibility, though it is not a renewable carbon-based feedstock.

Question 5

How does Sodium Chloride[1][3][4] work chemically?

Accepted Answer

The molecule is a simple inorganic 1:1 ionic crystal that dissociates completely in water and is stable across typical cosmetic pH ranges. In surfactant systems it is often used around 0.5% to 3% for viscosity building, but levels above the formulation’s optimum can reduce thickness instead of increasing it.
