Frequently Asked Questions (FAQ)

Question	Answer
What is Pyrrolidinyl Diaminopyrimidine Oxide and how does it work for hair loss?	Pyrrolidinyl Diaminopyrimidine Oxide (often compared to Aminexil/Kopexil) is a potent cosmetic active ingredient designed to combat hair loss. It works by preventing perifollicular fibrosis (the hardening of collagen around hair roots) and rejuvenating hair follicles. Shaanxi Huatai manufactures high-grade PDO to help brands formulate highly effective anti-hair loss serums and shampoos.
Is your Pyrrolidinyl Diaminopyrimidine Oxide water-soluble? How is it formulated?	Yes, the PDO produced by Shaanxi Huatai exhibits excellent water solubility. It can be easily dissolved in the aqueous phase of your cosmetic formulation. We recommend incorporating it into the water phase at temperatures below 50°C and maintaining the final formula pH between 4.0 and 7.0 for maximum stability.
What is the recommended usage rate for hair care formulations?	For optimal hair growth and follicle-strengthening efficacy, the recommended usage rate is typically 1.0% to 1.5%. The technical team at Shaanxi Huatai can provide detailed formulation guidelines whether you are developing a leave-on scalp serum, lotion, or daily shampoo.
How does Pyrrolidinyl Diaminopyrimidine Oxide differ from Minoxidil?	While Minoxidil is classified as a pharmaceutical drug with potential side effects, PDO is a highly effective, safe cosmetic alternative with no known systemic side effects. Global formulators trust Shaanxi Huatai’s PDO for developing compliance-friendly, over-the-counter (OTC) cosmetic hair growth products.
Do you provide a Certificate of Analysis (COA) and MSDS for wholesale orders?	Absolutely. Quality transparency is a core standard at Shaanxi Huatai. We provide a complete set of documentation for every batch, including the COA, MSDS, and detailed HPLC purity test reports, ensuring your final products meet strict international cosmetic regulations.
What is the Minimum Order Quantity (MOQ) and can I get a sample?	To support both large-scale commercial manufacturing and independent R&D labs, Shaanxi Huatai offers a highly flexible MOQ of just 1kg. We also provide 10g-50g free samples for your initial formulation compatibility and stability trials.
What is the shelf life and proper storage condition for bulk PDO?	When stored in a cool, dry place away from direct sunlight, the shelf life of Shaanxi Huatai‘s Pyrrolidinyl Diaminopyrimidine Oxide is 24 months. We recommend keeping the original bulk packaging tightly sealed to prevent moisture absorption.
Why source Pyrrolidinyl Diaminopyrimidine Oxide directly from your factory in China?	Sourcing directly from a source manufacturer like Shaanxi Huatai guarantees factory-direct competitive pricing, consistent batch-to-batch stability, and rapid global shipping (typically dispatched within 3-5 working days). You bypass distributors to gain direct access to our expert R&D and technical support.
