Sodium Dehydroacetate is a functional cosmetic ingredient used primarily for its preservative properties in suitable personal care and cosmetic formulations. It is the sodium salt associated with dehydroacetic acid and is identified by CAS Number 4418-26-2. The ingredient is commonly supplied as a white or nearly white powder and has useful solubility characteristics in water and selected formulation solvents. The FCC describes Sodium Dehydroacetate as a white or nearly white powder, with approximately 1 g dissolving in about 3 mL of water.
As a cosmetic preservative ingredient, Sodium Dehydroacetate can be considered by formulators when developing personal care products where microbial protection is required as part of an appropriately designed preservation system. Preservatives play an important role in reducing the risk of microbial contamination and maintaining product quality during storage and consumer use.
Swapnroop Drugs & Pharmaceuticals supplies Sodium Dehydroacetate as a technical cosmetic ingredient for manufacturers, formulators and bulk buyers looking for consistent-quality raw materials for personal care applications.
Sodium Dehydroacetate is chemically associated with 3-acetyl-6-methylpyran-2,4(3H)-dione and its salts. Its chemical formula is C₈H₇NaO₄, with a molecular weight of approximately 190.13 g/mol for the anhydrous form.

The European Commission's CosIng database provides the framework for cosmetic ingredient nomenclature and ingredient information used for cosmetic labelling in the EU.
Preservation is an important part of cosmetic formulation development, particularly for products containing water or other components that may support microbial growth. A suitable preservative system helps formulators maintain product quality throughout the intended shelf life and period of consumer use.
Sodium Dehydroacetate cosmetic ingredient is therefore relevant to manufacturers researching preservative systems for personal care formulations. Its use should always be evaluated according to the formulation's pH, water activity, packaging, processing conditions, microbial challenge-test results and applicable cosmetic regulations.
For manufacturers searching for a Sodium Dehydroacetate preservative ingredient, the technical quality and consistency of the raw material are important considerations. Ingredient identity, purity, moisture, appearance, solubility and other quality parameters should be controlled according to the applicable product specification.
Sodium Dehydroacetate may be considered for suitable cosmetic and personal care formulations where a preservative ingredient is technically and legally appropriate.
Potential formulation areas include:
The actual suitability and permitted concentration depend on the finished formulation, target market and applicable regulations.
When using Sodium Dehydroacetate as a cosmetic ingredient, formulators should consider the complete preservation system rather than evaluating the ingredient in isolation.
Important formulation parameters include:
The pH of the finished formulation can influence preservative performance and should be evaluated during formulation development.
Because Sodium Dehydroacetate has useful water solubility, formulators should assess its incorporation into the aqueous phase and verify complete dispersion or dissolution under the intended manufacturing conditions.
Compatibility with surfactants, emulsifiers, humectants, botanical extracts, fragrances, active cosmetic ingredients and other formulation components should be assessed through stability testing.
The final packaging system can influence contamination risk and preservation requirements. Packaging compatibility should therefore be evaluated as part of finished-product development.
Finished cosmetic products should undergo appropriate microbiological quality and preservative-efficacy testing according to the manufacturer's quality and regulatory requirements.
The FCC describes Sodium Dehydroacetate as a white or nearly white powder and reports that approximately 1 g dissolves in about 3 mL of water, 2 mL of propylene glycol, and 7 mL of glycerin. These values are useful technical references for formulation development, although actual solubility can vary with grade, temperature, hydration state and formulation conditions.
This makes solubility an important parameter when developing aqueous or water-containing cosmetic formulations.
For professional cosmetic ingredient procurement, a consistent specification is important. Typical quality evaluation may include:
The applicable specification should correspond to the actual grade being supplied and its supporting Certificate of Analysis.
Where a pharmacopoeial or FCC reference is used, it should not automatically be interpreted as a claim that every cosmetic-grade batch is compliant with that standard. The FCC reference identifies Sodium Dehydroacetate as C₈H₇NaO₄·H₂O with a formula weight of 208.15 for the monohydrate form.
Regulatory requirements are particularly important when Sodium Dehydroacetate is intended for cosmetic products sold internationally.
Under the European Union cosmetics framework, dehydroacetic acid and sodium dehydroacetate are listed together under the preservative provisions. The cited Annex V entry specifies a maximum concentration of 0.6% expressed as acid and states that the substances are not to be used in aerosol dispensers (sprays).
This concentration is a finished cosmetic product regulatory limit, not a raw-material assay specification. Cosmetic manufacturers must evaluate the concentration in the finished product and comply with the regulations applicable to the target market.
