Sodium Anisate is the sodium salt of p-Anisic Acid (4-Methoxybenzoic Acid) and is identified by the INCI name SODIUM ANISATE. It is used in cosmetic and personal-care formulations primarily for antimicrobial, fragrance, flavouring and pH-adjusting functionality. COSMILE Europe identifies all four of these functions for Sodium Anisate in cosmetic products.
Sodium Anisate is particularly relevant to formulation systems looking for a multifunctional ingredient that can contribute to microbial-control strategies while also fitting into fragrance and pH-management approaches. It is distinct from Anisic Acid itself: Sodium Anisate is the sodium salt and consequently has different physical and formulation characteristics.
Sodium Anisate has CAS Number 536-45-8 and EC Number 208-634-1. Its chemical name is sodium 4-methoxybenzoate, and it has the molecular formula C₈H₇NaO₃ with a molecular weight of 174.13 g/mol. PubChem identifies 536-45-8 as the CAS number and lists Sodium Anisate, sodium p-anisate and sodium p-methoxybenzoate among its synonyms.
The compound is derived chemically from the parent structure of 4-Methoxybenzoic Acid. The sodium carboxylate form gives the material properties that differ from the free acid, particularly in relation to water compatibility and formulation handling.
Commercial cosmetic references commonly describe Sodium Anisate as a white powder and as a water-soluble ingredient. However, the exact appearance, moisture level, assay and particle characteristics depend on the commercial grade and manufacturing specification.
Sodium Anisate has several documented cosmetic functions. COSMILE Europe identifies it as an antimicrobial, helping control the growth of microorganisms such as bacteria and fungi. It is also listed as a flavouring, fragrance and pH-adjusting ingredient.
Its antimicrobial functionality makes Sodium Anisate relevant to preservation-support systems. It may be incorporated with other preservation ingredients when formulators require a broader preservation approach. It should not, however, be assumed that the ingredient alone provides complete preservation for every cosmetic formulation. Preservation efficacy depends on the entire formulation, packaging, pH, water activity and microbial challenge profile.
The ingredient's pH-adjusting and fragrance-related functions can also make it useful in multifunctional cosmetic formulations where several formulation objectives need to be addressed through a coordinated ingredient system.
Sodium Anisate can be evaluated in skin-care, hair-care, cleansing and other personal-care formulations. Commercial formulation references document its presence in products such as shampoos and skin-care preparations.
It can be considered for formulations where antimicrobial support is required together with compatibility with water-based cosmetic systems. The ingredient is also used in formulations marketed around naturally derived or multifunctional preservation concepts, although claims regarding natural origin should be based on the actual manufacturing route and supplier documentation.
Because Sodium Anisate is a salt of p-Anisic Acid, it can also be considered where an anisate-based ingredient is preferred over the free acid. Its actual role and use level should be established according to the finished formulation and target-market requirements.
Sodium Anisate is reported as soluble in water, which can be advantageous when developing aqueous personal-care formulations.
The appropriate use level depends on the formulation's preservation strategy, pH, water activity, other antimicrobial ingredients and packaging system. Commercial formulation references report use levels such as 0.05–0.4%, but these are formulation-industry recommendations rather than a universal regulatory maximum or a mandatory raw-material specification.
For quality control, the actual SDP specification should be used for assay, moisture, ash, pH and impurity parameters. A supplier's commercial specification should not automatically be represented as a pharmacopoeial standard.
As a Sodium Anisate Cosmetic Ingredient Manufacturer in India, Swapnroop can position Sodium Anisate for B2B cosmetic and personal-care raw-material requirements, subject to the actual commercial grade and specification.
Customers looking for a Sodium Anisate supplier in India can evaluate the material based on CAS identity, molecular characteristics, appearance, assay, moisture, solubility and batch-specific quality documentation.
For bulk cosmetic ingredient supply, the selected grade should be matched with the intended formulation, preservation system and destination-market requirements. Sodium Anisate can be particularly relevant for manufacturers seeking a multifunctional anisate ingredient for modern personal-care formulations.
