Import 4-Chloro-3,5-Dimethylphenol (Pcmx) — Buy in Bulk from Supplier in China

4-Chloro-3,5-Dimethylphenol (PCMX), also known as Chloroxylenol, is a chlorinated phenolic compound with the molecular formula C8H9ClO and a molecular weight of 156.57 g/mol. Aurora Industry Co., Ltd. offers this antimicrobial active with typical purity levels of 98.5% minimum (standard cosmetic/pharmaceutical grade), appearing as white to off-white crystalline powder or needles with a characteristic phenolic odour. The compound exhibits a melting point range of 114-116 degrees Celsius and demonstrates solubility in alcohol, ether, and alkaline solutions, with limited solubility in water (approximately 0.03% at 20 degrees Celsius), which determines its formulation behaviour in aqueous cosmetic systems.

The antimicrobial mechanism of PCMX involves disruption of microbial cell membranes, effective against Gram-positive bacteria, some Gram-negative bacteria, and fungi at typical use concentrations of 0.3-3.0% in finished formulations. Standard production involves chlorination of 3,5-dimethylphenol under controlled conditions, with subsequent purification to remove residual starting materials and by-products such as dichlorinated species. The product is typically supplied with specified limits on free phenol content (commonly below 0.5%) and moisture content (typically below 0.5%), parameters that influence stability and performance in preservative applications. pH stability extends across 4-10 in most formulation matrices, though alkaline conditions can cause gradual degradation and colour development over extended storage.

PCMX finds primary application as a preservative and antimicrobial active in personal care products including liquid soaps, shampoos, skin creams, and deodorants, where it functions at 0.3-1.0% concentration depending on challenge test requirements and regulatory limits. The compound also serves in industrial disinfectants, hospital-grade sanitizers, and some pharmaceutical preparations. Buyers should confirm with Aurora Industry Co., Ltd. the exact purity specification, certificate of analysis batch protocol, and whether the material is offered as USP/EP grade or cosmetic grade. Typical packaging for bulk pharmaceutical and cosmetic raw materials ranges from 25 kg fibre drums to 500 kg bulk containers; confirm MOQ, lead time, and available Incoterms directly with the supplier, as these details are not stated in the source data.

Aurora Industry Co., Ltd. is listed as an imported-tier supplier based in China, classified under the harbour trust tier with a response rate of 0.00% and zero recorded average response hours. This profile indicates limited active engagement signals on the platform, and buyers should expect to initiate contact and verify responsiveness directly. The supplier's location in China positions it within the global hub for fine chemical and pharmaceutical intermediate manufacturing, though specific factory details, production capacity, and quality management certifications are not disclosed in the available data.

The source description attributes several claims to the supplier, including references to ISO and FDA compliance, though buyers must independently verify the scope and validity of any certifications cited, as no certificate numbers, accreditation dates, or certifying body details are provided. The listing does not state specific MOQ, price, lead time, packaging configurations, or Incoterms, and these must be confirmed through direct negotiation. No information about company history, employee count, annual revenue, facility audits, or named clients is available, and no such details should be assumed.
