Import Acid Green 20 — Buy in Bulk from Supplier in India

Acid Green 20 (CAS 5850-39-5) is an acid dye supplied by Krishna Impex from India, characterized by a concentrated green hue formulated for textile, plastics and cosmetic applications. The listing indicates a dye strength of 40%, a figure that refers to the standardised color concentration rather than purity, which allows dilution ratios to be calculated for consistent shade reproduction across batches. This water-soluble synthetic dye belongs to the monoazo or anthraquinone class typical of acid dyes, though the specific chromophore is not stated in the source data.

The 40% strength specification is a measured attribute from the listing; typical industry practice for acid dyes ranges from 20% to 50% depending on the chromophore and intended substrate. Acid Green 20 demonstrates affinity for protein fibres (wool, silk, nylon) through ionic bonding with amino groups, with standard bath pH typically maintained between 2.0 and 5.5 using formic or acetic acid. Light fastness ratings for acid green dyes of this class typically fall between 4 and 6 on the ISO Blue Scale, though the supplier-specific rating should be requested. The dye exhibits good levelling properties and moderate wet fastness, characteristics that trade buyers validate through ISO 105-C06 wash fastness and ISO 105-X12 rubbing fastness tests before bulk commitment.

Primary applications include wool and silk piece dyeing, nylon hosiery, leather finishing and selected cosmetic colourants where regulatory approval permits. Industrial buyers typically specify liquid or powder form, with powder being standard for freight efficiency; packaging details from this supplier are not stated and should be confirmed. Payment structures referenced include letter of credit (L/C), a conventional instrument for Indian dye exports that mitigates counterparty risk. CIF terms are mentioned, placing freight and insurance obligation on the seller through to destination port, though the specific loading port in India is unstated.

Krishna Impex operates from B-10, Om Sai Industrial Estate, Bhayander East Phatak Road, Thana 401105, Maharashtra, India. The supplier holds a harbour trust tier classification and imported supplier tier designation, with both response rate and average response hours recorded at zero in the available data. This profile indicates limited transactional visibility on the platform rather than operational assessment, and buyers should conduct independent due diligence on production capacity and quality management systems.

The listing presents Acid Green 20 with an emphasis on export orientation and bulk supply capability, referencing ISO and CE certifications in its source description. Buyers should independently verify the scope and validity of any claimed certifications, including the certifying body, standard number and expiry date, as these details are not substantiated in the source data. No workforce size, annual turnover, factory ownership structure, or named client references are present in the profile, and none should be assumed.
