Diaminopyrimidine oxide

Diaminopyrimidine Oxide is a potent hair growth stimulant primarily used in anti-hair loss lotions, shampoos, and scalp treatments. It works by softening collagen around the hair follicle, which prevents the hardening of the hair root (fibrosis) and ensures better nutrient delivery. It is an ideal alternative to Minoxidil for cosmetic formulations because it offers similar efficacy with lower irritation levels and better solubility in water-based systems.

Buyers must prioritize a purity level of ≥99% to ensure maximum biological activity and safety. Key parameters include Heavy Metal content (<10ppm), Arsenic (<2ppm), and a strictly controlled pH range (typically 4.0 - 6.0 in solution). Additionally, verify the Loss on Drying (≤0.5%) to ensure the stability of the powder during long-term storage and transport.

As a cosmetic raw material, it must comply with the International Nomenclature of Cosmetic Ingredients (INCI). Suppliers should provide a comprehensive Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) for every batch. For entry into the EU market, ensure the supplier follows REACH regulations, and for the US, verify compliance with PCPC (Personal Care Products Council) guidelines.

Diaminopyrimidine Oxide is highly soluble in water and ethanol, which simplifies the manufacturing process and reduces the need for expensive solubilizers. This high solubility allows for stable formulations at concentrations of 1% to 5%, providing a cost-effective solution for high-performance hair care lines. Buyers should request solubility test reports to avoid precipitation issues in final products.

Diaminopyrimidine Oxide is sensitive to light and moisture. Ensure the supplier uses double-layer PE bags inside fiber drums with vacuum sealing. Request temperature-controlled shipping if passing through tropical zones and insist on shading labels to prevent UV degradation. Using Made-in-China.com's verified suppliers can help ensure that packaging standards meet international chemical transport protocols.

Focus on tiered pricing based on volume, as bulk orders (e.g., >100kg) can often secure a 15-25% discount. Negotiate for free pilot-scale samples (10g-50g) before committing to a bulk purchase. Additionally, request a long-term price lock agreement to protect your margins against fluctuations in raw material costs for pyrimidine derivatives.

Always utilize Trade Assurance services provided by platforms like Made-in-China.com to protect your payment until the goods are verified. For first-time orders, employ a third-party inspection agency (like SGS or Intertek) to conduct a Pre-Shipment Inspection (PSI) to verify the purity and weight of the chemical at the factory.

Ensure the HS Code (typically 2933.59) is accurately declared to avoid delays. Provide a clear Non-DG (Non-Dangerous Goods) Declaration if applicable, supported by a BUREAU VERITAS or DGM report for air freight. This prevents the shipment from being flagged as hazardous, significantly reducing shipping costs and clearance time.
