Sodium Dehydrocetate ●
TL;DR. This ingredient is a preservative used to help protect water-containing formulas from bacteria, yeast, and mold. It is most often used as part of a broader preservation system rather than as the only antimicrobial.
What does Sodium Dehydrocetate do in a cosmetic formula?
This ingredient is a preservative used to help protect water-containing formulas from bacteria, yeast, and mold. It is most often used as part of a broader preservation system rather than as the only antimicrobial.
Is Sodium Dehydrocetate clean?
From a clean-beauty perspective, this ingredient is generally accepted, with some scrutiny because it is a synthetic preservative. It has a relatively low sensitization profile, but use levels and pH range matter for performance and tolerability.
Is Sodium Dehydrocetate sustainable?
This material is typically synthetically produced rather than directly plant-derived. It is used at low levels, but its Green Chemistry profile is moderate because renewable sourcing and full biodegradation data are not its strongest points.
Is Sodium Dehydrocetate COSMOS-approved?
It is permitted under COSMOS for natural and organic cosmetics when used as an allowed preservative within the standard’s conditions. It fits better on safety and low-dose efficiency than on renewable feedstock or minimal-processing criteria.
How does Sodium Dehydrocetate work chemically?
The molecule is a sodium salt of a heterocyclic beta-dicarbonyl preservative acid, and antimicrobial activity depends on the acid-base balance in the formula. Typical use is about 0.1% to 0.6%, with best performance in mildly acidic systems, commonly below about pH 6.
