Procurement managers in the chemical and cosmetic industries face the constant challenge of sourcing high-quality raw materials at competitive prices while ensuring supply chain reliability. For those involved in hair dye formulation, 2,4-Diaminophenoxyethanol sulfate (CAS 70643-20-8) is a key ingredient that demands careful sourcing. This article provides a guide for procurement professionals looking to buy 2,4-diaminophenoxyethanol sulfate from trusted sources.

The Importance of 2,4-Diaminophenoxyethanol Sulfate in Hair Dyes

As a crucial coupler in oxidative hair dyes, 2,4-Diaminophenoxyethanol sulfate plays a direct role in the color development process. It reacts with other components to form stable dye molecules within the hair fiber, leading to vibrant and long-lasting color results. The quality of this intermediate directly impacts the final product's performance, including shade accuracy, color intensity, and resistance to fading. Therefore, understanding its specifications is critical for procurement decisions.

Key Specifications for Procurement

When evaluating suppliers, procurement managers should prioritize products that meet stringent quality standards. For 2,4-Diaminophenoxyethanol sulfate, key specifications to look for include:

  • Purity (HPLC): Aim for a minimum purity of ≥98.0%. Higher purity ensures fewer by-products and more predictable reactions.
  • Appearance: An off-white to light purple crystalline powder is standard. Consistency in appearance can be an indicator of consistent manufacturing.
  • Ash Content: Low ash content (≤0.5%) signifies minimal inorganic impurities.
  • Moisture Content: Controlled moisture levels (11.5-12.5%) are important for product stability and handling.
  • Iron (Fe) Content: Low iron content (≤100ppm) is vital to prevent unwanted side reactions or color interference in formulations.

These specifications are critical for ensuring the efficacy and safety of the final hair dye product. A reliable hair dye intermediate supplier will readily provide Certificates of Analysis (CoA) detailing these parameters.

Navigating the Supply Chain: Choosing a Manufacturer

China has emerged as a significant global hub for chemical manufacturing, offering competitive pricing and vast production capacities. When looking for a 2,4-diaminophenoxyethanol sulfate manufacturer in China, it is essential to vet potential partners carefully. Factors to consider include:

  • Manufacturing Capabilities: Does the manufacturer have the capacity to meet your volume requirements?
  • Quality Control Systems: Do they have robust QC processes in place and can they provide consistent quality documentation?
  • Regulatory Compliance: Are their products compliant with relevant international cosmetic ingredient regulations?
  • Customer Service and Support: Is the supplier responsive and able to assist with technical inquiries or sample requests?
  • Pricing: Compare the 2,4-diaminophenoxyethanol sulfate price across different suppliers, considering the overall value proposition.

For procurement professionals actively seeking where to purchase cosmetic chemical, understanding these aspects will lead to more informed decisions. Partnering with an established 2,4-diaminophenoxyethanol sulfate supplier that prioritizes quality and reliability is key to a successful procurement strategy.
