What is Sodium Anisate and how is it identified?

Sodium anisate is the sodium salt of 4-methoxybenzoic acid with CAS 536-45-8, molecular formula C₈H₇NaO₃ and molecular weight 174.13. It is also called sodium p-methoxybenzoate or sodium 4-methoxybenzoate.

Which specifications should be confirmed for cosmetic use?

Confirm assay, appearance, color, moisture, pH and related benzoate impurities. The batch analysis should state the actual purity and test method because this material is used in preservation-supporting systems and cosmetic formulations.

What is Sodium Anisate used for?

It is used in cosmetics and personal-care preservation systems, often together with other organic acids or humectants, to help control microbial growth while supporting mild preservative-free or alternative-preservation claims.

How should Sodium Anisate be stored and handled?

Store in tightly closed containers in a cool, dry, ventilated area away from strong oxidizers and direct sunlight. Use dust controls, normal chemical-handling PPE and the current safety information for spill and disposal procedures.

How does Sodium Anisate support preservative-free cosmetic systems?

Sodium anisate is used as a preservation-supporting organic acid salt and is often combined with other mild organic acids or humectants. It helps control microbial growth while allowing formulators to reduce or avoid conventional preservatives in suitable product systems.
