Triclosan is a specialty cosmetic ingredient with established antimicrobial and preservative functionality. It is identified by the INCI name TRICLOSAN, CAS Number 3380-34-5, and EC Number 222-182-2. Chemically, Triclosan is 5-chloro-2-(2,4-dichlorophenoxy)phenol, with the molecular formula C₁₂H₇Cl₃O₂ and molecular weight 289.54 g/mol.
Triclosan has historically been used in personal-care formulations where antimicrobial performance is required. Chemical references describe its use in products such as soaps, skin creams, toothpaste and deodorants, although the permitted uses and maximum concentrations depend on the regulatory market and product category.
For cosmetic manufacturers and procurement teams searching for a Triclosan cosmetic ingredient manufacturer in India or Triclosan supplier in India, the material should be evaluated based on chemical identity, purity, analytical specification, regulatory requirements, formulation compatibility and batch documentation.
Triclosan is a chlorinated aromatic ether containing three chlorine atoms and two oxygen atoms. Its systematic chemical name is 5-chloro-2-(2,4-dichlorophenoxy)phenol. It is commonly described as a white to off-white crystalline powder with a faint aromatic odour.
Its key technical identity is:

PubChem reports the molecular formula as C₁₂H₇Cl₃O₂ and molecular weight as 289.5 g/mol, while the USP-NF monograph gives 289.54 g/mol.
Triclosan's relevance as a cosmetic ingredient comes primarily from its antimicrobial activity. It has been used in personal-care products where microbial control is an important formulation consideration. However, antimicrobial ingredients must be evaluated within the complete formulation because factors such as pH, solvent system, packaging, ingredient compatibility and product type can influence preservation performance.
Triclosan is relatively hydrophobic and has limited water solubility. Published data report water solubility of approximately 10 mg/L at 20°C, while it is more readily soluble in alkaline solutions and several organic solvents.
This physical behaviour is important when developing formulations because the method used to incorporate Triclosan should be selected according to the formulation's solvent system and processing conditions.
Triclosan has historically been associated with several personal-care applications, including:
However, application suitability must always be checked against the regulations of the destination market. A historical application does not automatically mean that the ingredient is permitted at the same concentration or in the same product category today.
Formulators working with Triclosan should consider its physical properties, concentration, solvent system and compatibility with other ingredients.
Its melting point is reported at approximately 54–57.3°C, and it is described as slightly soluble in water.
Because of its low aqueous solubility, formulation developers may need to consider suitable solvents, solubilization systems or dispersion approaches depending on the final formulation. The selected processing method should be validated during formulation development rather than assumed from a general ingredient description.
The preservative system should also be evaluated in the finished formulation. Factors including pH, water activity, packaging, microbial challenge results and interactions with other raw materials can influence overall preservation performance.
A Triclosan cosmetic ingredient manufacturer in India should provide material supported by a defined product specification and appropriate analytical documentation. For B2B procurement, buyers commonly need information covering chemical identity, assay, appearance, impurity profile, moisture or water content where applicable, packaging and batch-specific Certificate of Analysis documentation.
The actual commercial specification should always be used for release and procurement purposes. Generic values from unrelated suppliers should not be represented as SDP specifications.
For manufacturers purchasing Triclosan in bulk, consistent analytical testing and traceability are important because the raw material becomes part of a controlled cosmetic manufacturing process.
A Triclosan cosmetic ingredient supplier in India can support procurement requirements by providing technical information relevant to the intended cosmetic application.
Before purchasing, manufacturers should evaluate:
This type of technical evaluation is particularly important for ingredients such as Triclosan because regulatory conditions can differ significantly according to the final product category and country.
Triclosan manufacturing in India for cosmetic-ingredient applications requires controlled production and quality testing to achieve the required chemical identity and purity.
For bulk buyers, supply arrangements can include product-specific specifications, packaging requirements and batch documentation. The appropriate commercial specification should be agreed before supply, particularly where the buyer has defined limits for assay, impurities, moisture or physical characteristics.
For businesses searching for Triclosan bulk cosmetic ingredient supplier in India, the purchasing decision should therefore consider both technical quality and the regulatory status of the intended finished product.
