Question 1

What does Sodium Dehydroacetate. Stark: Kaolin do in a cosmetic formula?

Accepted Answer

This ingredient functions primarily as a preservative, with strongest utility against yeasts and molds in water-containing formulas.

Question 2

Is Sodium Dehydroacetate. Stark: Kaolin clean?

Accepted Answer

Clean-beauty frameworks generally accept it when used within preservative limits, but it is still concentration-controlled and more commonly seen in formulas that need fungal protection. It has a relatively low sensitization profile, though irritation can occur at higher exposure or in sensitive skin contexts.

Question 3

Is Sodium Dehydroacetate. Stark: Kaolin sustainable?

Accepted Answer

This material is typically made through synthetic chemistry rather than direct plant extraction. It is not known as a major bioaccumulative concern, but its petroleum-linked feedstock and preservative-specific use keep its sustainability profile moderate rather than strongly aligned.

Question 4

Is Sodium Dehydroacetate. Stark: Kaolin COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic standards as an allowed preservative, within specified limits. From a Green Chemistry view, it earns points for effective low-dose preservation, but less so for renewable sourcing.

Question 5

How does Sodium Dehydroacetate. Stark: Kaolin work chemically?

Accepted Answer

The molecule is a sodium salt of a cyclic beta-dicarbonyl acid, which improves water compatibility compared with its free-acid form. In cosmetics it is typically used at low preservative levels, with regulatory limits commonly expressed as up to 0.6% calculated as the acid, and it performs best in mildly acidic to near-neutral systems.
