Anisic Acid is an aromatic carboxylic acid belonging to the methoxybenzoic acid family. In cosmetic and personal-care ingredient terminology, p-Anisic Acid (4-Methoxybenzoic Acid) is the commonly referenced form. Its chemical structure combines a benzene ring, a methoxy group and a carboxylic acid group.
Anisic Acid is used in specialty cosmetic formulations and fragrance-related applications. Cosmetic ingredient databases identify P-Anisic Acid as a cosmetic ingredient associated with the fragrance category, while anisate derivatives such as Sodium Anisate are recognized for antimicrobial, fragrance and pH-adjusting functions.
For raw-material procurement, it is important to distinguish Anisic Acid itself from its salts and esters. Sodium Anisate, for example, has a different chemical identity and should have separate product specifications.
The most commonly referenced Anisic Acid is p-Anisic Acid, also called 4-Methoxybenzoic Acid. It has CAS Number 100-09-4, EC Number 202-818-5, molecular formula C₈H₈O₃, and molecular weight 152.15 g/mol. PubChem also identifies 100-09-4 as a CAS number for 4-Methoxybenzoic Acid.
The compound is an aromatic acid containing one methoxy substituent. The para arrangement of the methoxy group relative to the carboxylic acid group gives p-Anisic Acid its characteristic chemical identity. TCI identifies its product as p-Anisic Acid and lists 4-Methoxybenzoic Acid as the synonym.
TCI's current reference material is specified at greater than 99.0% purity by GC, demonstrating the availability of high-purity material for analytical and specialty applications. This is a supplier-specific specification and should not automatically be used as the SDP commercial release specification.
P-Anisic Acid is associated with fragrance functionality in cosmetic ingredient references. It can contribute to the aromatic profile of a formulation or be used as a specialty raw material in fragrance-related systems. COSMILE Europe lists P-Anisic Acid among fragrance/perfume-related substances and identifies its common name as 4-Methoxybenzoic Acid.
Anisic Acid should not be automatically described as a conventional cosmetic preservative simply because some of its derivatives have antimicrobial properties. For example, COSMILE Europe identifies Sodium Anisate separately as an antimicrobial, flavouring, fragrance and pH-adjusting ingredient.
This distinction is important when preparing technical documentation because the acid, sodium salt and other anisate derivatives have different chemical properties and regulatory considerations.
Anisic Acid can be evaluated in cosmetic, personal-care, fragrance and specialty chemical applications. Its aromatic structure makes it relevant to fragrance-related ingredient systems, while its carboxylic acid functionality provides a useful chemical intermediate for the production of other derivatives.
In personal-care raw-material development, p-Anisic Acid may be considered where a defined aromatic acid is required as a formulation component or specialty intermediate. Its application should be determined according to the final formulation, concentration, compatibility and regulatory requirements of the destination market.
Anisic Acid can also serve as a chemical building block for preparing anisate derivatives. This is particularly relevant to manufacturers developing customized cosmetic raw-material systems.
Anisic Acid should be evaluated according to the actual grade, purity, particle characteristics, storage conditions and intended application. Because it is an organic acid, its behaviour in a finished formulation can be influenced by pH, neutralization, solvent system and the presence of other formulation components.
The physical and analytical properties of commercial material can vary according to grade. TCI currently lists >99.0% GC purity for its p-Anisic Acid reference product. The analytical method is important: a GC purity specification should not be converted into an HPLC specification without an appropriate validated method.
For SDP's CMS, the final assay value should therefore be based on the actual SDP Certificate of Analysis and validated analytical procedure.
As an Anisic Acid Cosmetic Ingredient Manufacturer in India, Swapnroop can position p-Anisic Acid for B2B cosmetic, personal-care, fragrance and specialty raw-material requirements, subject to the actual commercial grade and specification.
Customers looking for an Anisic Acid supplier in India can evaluate the material through its chemical identity, purity, physical properties and batch-specific quality documentation. For bulk cosmetic ingredient supply, the selected grade should be matched with the intended application and destination-market requirements.
Where the requirement specifically concerns an antimicrobial cosmetic ingredient, buyers should distinguish Anisic Acid from Sodium Anisate, because they are separate substances with different documented cosmetic functions.
