Sodium Salicylate is the sodium salt of salicylic acid and is a technically defined ingredient used in suitable cosmetic and personal-care formulations. It is identified chemically as 2-hydroxybenzoic acid monosodium salt, with the molecular formula C₇H₅NaO₃, molecular weight 160.10 g/mol, and CAS Number 54-21-7.
In cosmetic applications, Sodium Salicylate is recognized for preservative functionality. COSMILE Europe identifies SODIUM SALICYLATE as a cosmetic ingredient with PRESERVATIVE and DENATURANT functions.
For manufacturers searching for Sodium Salicylate Cosmetic Ingredient Manufacturer in India, Sodium Salicylate Cosmetic Grade, Sodium Salicylate Preservative, Sodium Salicylate Personal Care Ingredient, or Sodium Salicylate Bulk Ingredient, raw-material identity, purity, analytical specifications and applicable cosmetic regulations are important considerations.
Sodium Salicylate is the monosodium salt of salicylic acid (2-hydroxybenzoic acid). Replacing the acidic hydrogen of salicylic acid with sodium produces the corresponding sodium salt.
The chemical identity is:
These values are directly supported by the USP-NF monograph.

Sodium Salicylate cosmetic ingredient is relevant to manufacturers developing personal-care products where a salicylate-based functional ingredient is appropriate.
COSMILE Europe specifically lists Sodium Salicylate as a preservative, explaining that preservatives help protect cosmetic products from microbial spoilage. It also lists a denaturant function.
For formulation development, Sodium Salicylate should be evaluated within the complete formulation system. Factors such as pH, water phase, other preservatives, packaging, processing conditions and finished-product stability can affect the performance of a preservation system.
Potential areas for evaluation include:
The actual suitability of Sodium Salicylate depends on the finished formulation, concentration, product type and regulations applicable to the target market.
Preservation is particularly important for cosmetic formulations containing water because microorganisms can potentially grow in aqueous environments.
Sodium Salicylate can be evaluated as part of an appropriately designed preservation system. COSMILE Europe notes that cosmetic products often use combinations of preservative substances and that preservation systems can act against different groups of microorganisms.
Formulators should therefore evaluate:
A raw-material specification alone does not establish the effectiveness of a preservative system in a finished cosmetic product.
When developing a Sodium Salicylate cosmetic formulation, the ingredient should be evaluated according to the physical and chemical characteristics of the final product.
Important formulation considerations include:
Finished-product pH should be evaluated because it can affect ingredient behaviour and the overall preservation system.
Compatibility with surfactants, emulsifiers, humectants, botanical extracts, fragrances and other cosmetic ingredients should be evaluated.
The actual solubility of the supplied grade should be confirmed under the intended formulation conditions, including temperature and concentration.
The final packaging system can influence microbial contamination risk and should be considered during preservation-system development.
Accelerated and real-time stability studies can help evaluate the physical and chemical stability of the finished formulation.
Quality control is an important consideration when purchasing Sodium Salicylate as a cosmetic ingredient.
The USP-NF monograph defines Sodium Salicylate as containing NLT 98.0% and NMT 102.0%, calculated on the anhydrous basis.
This is the most useful verified numeric assay reference for the CMS specification. It should not automatically be entered into a field labelled Assay (HPLC) because the USP monograph's definition does not establish that the 98.0–102.0% value is an HPLC assay.
Important quality-control parameters can include:
The USP monograph specifically identifies USP Phenol RS, USP Salicylic Acid Related Compound A RS, USP Salicylic Acid Related Compound B RS, and USP Sodium Salicylate RS among the reference standards used for the monograph.
For businesses searching for a Sodium Salicylate Manufacturer in India, reliable product identity, analytical specifications and technical documentation are important during raw-material qualification.
Swapnroop Drugs & Pharmaceuticals provides technical ingredient information for manufacturers, formulators, R&D teams and bulk buyers evaluating cosmetic and personal-care raw materials.
Sodium Salicylate can be evaluated for bulk ingredient requirements according to the required grade, specification, packaging and intended application.
Bulk procurement of Sodium Salicylate cosmetic ingredient may require evaluation of:
This information helps cosmetic manufacturers and formulation companies establish suitable raw-material qualification procedures.
Sodium Salicylate and Salicylic Acid are chemically related but are not the same raw material.
Salicylic Acid is the free acid with the molecular formula C₇H₆O₃ and molecular weight 138.12 g/mol, whereas Sodium Salicylate is its sodium salt with the formula C₇H₅NaO₃ and molecular weight 160.10 g/mol. The USP-NF monograph identifies Sodium Salicylate as the monosodium salt of 2-hydroxybenzoic acid.
This distinction is important when creating product pages, specifications, purchasing documentation and formulation records.
COSMILE Europe lists SODIUM SALICYLATE as a cosmetic ingredient and identifies its functions as preservative and denaturant.
Cosmetic regulations differ between markets. Therefore, the presence of Sodium Salicylate in an ingredient database should not by itself be interpreted as unrestricted approval for every cosmetic product type or concentration.
Manufacturers should verify the current requirements applicable to the finished product, intended function, concentration and destination market.
Sodium Salicylate is positioned for suitable personal-care and cosmetic ingredient requirements.
CAS number, molecular information, product identity and relevant specifications support professional raw-material evaluation.
The product can be evaluated for B2B and bulk ingredient procurement according to the required grade and specification.
Appropriate technical and batch documentation can support raw-material qualification.
Technical information helps R&D and formulation teams assess Sodium Salicylate for appropriate cosmetic applications.
