从India供应商批量进口Acid Yellow 23

Acid Yellow 23, commonly identified as Tartrazine or C.I. 19140 with CAS 1934-21-0, is a monoazo acid dye supplied by Aryan Dyes & Pigments from Surat, Gujarat, India. This listing presents the product across multiple industrial segments including food coloration, ink manufacture, pond dyes, and textile coloration, indicating a general-purpose rather than application-specific grade. The supplier explicitly states a minimum order quantity of 100 kg, positioning the offering at small-to-medium industrial scale rather than bulk commodity volume. Exact specifications such as dye content, moisture percentage, and insoluble matter remain unstated in the source material, requiring direct technical inquiry.

The powder format and broad application claims suggest standard commercial milling without specialised surface treatment or microencapsulation. In textile contexts, Acid Yellow 23 exhibits affinity for protein fibres (wool, silk, nylon) through ionic bonding between sulphonate groups and cationic fibre sites. The dye's tinctorial strength and brightness derive from the pyrazolone coupling component, though lightfastness ratings are moderate (typically 3 to 4 on the ISO Blue Scale for wool). For food and cosmetic applications, regulatory status varies by jurisdiction: the dye is permitted in the EU (E102) with concentration limits, banned in several countries, and restricted in the US (FDA-certified batches only). Aryan Dyes & Pigments does not specify which regulatory frameworks this particular grade satisfies.

Buyers span food manufacturers seeking certified colour batches, textile dyehouses requiring consistent shade reproducibility, and ink formulators needing specific viscosity and particle size profiles. The supplier's mention of detergent and cleaner applications points to colour stability in alkaline surfactant systems, a property not universal among acid dyes. Packaging is described only as 'safe packaging of the best quantities', a vague assurance that demands clarification of container type, net weight, and UN certification for chemical transport. Delivery commitments are asserted without timeline specifics, making confirmation of production capacity and current stock levels a priority for time-sensitive procurement.

Aryan Dyes & Pigments is located at 806, Valentina Business Hub, near Shell Petrol Pump, L.P. Savani Road, New Adajan, Surat, Gujarat 395009, India. The company holds a Harbor trust tier on the platform, with zero recorded response rate and no average response time data. These engagement metrics suggest limited active platform communication, necessitating direct outreach via the provided0 provided contact details for reliable correspondence.

The source description emphasises affordability and on-time delivery without substantiating manufacturing scale, export experience, or quality accreditation. No information regarding company founding year, employee count, production capacity, or existing international client base is present in the listing. The broad application claims (food, ink, textiles, detergents, pond dyes) imply either multiple grade stocks or a single general-purpose grade marketed across sectors. Buyers should request GST registration, company incorporation documents, and any available quality system certification to assess operational legitimacy before committing to the 100 kg minimum order.
