Product Introduction

D Biotin Powder is the biologically active stereoisomer of Vitamin B7 (also known as Vitamin H or Coenzyme R). It is a water-soluble B-complex vitamin and a required cofactor for the carboxylase enzyme in fatty acid synthesis, gluconeogenesis, and amino acid catabolism.

The D-isomer is distinct from ordinary DL-biotin in its stereochemical purity. The racemic DL version contains 50% inactive L-biotin that your body is not able to use. The D version provides 100% bio-efficacy in each gramme.

Its crystalline structure also gives thermal stability, making it stable during high stress operations such as pharmaceutical tabletting and animal feed steam pelleting.

D Biotin Powder Specification

Third-Party Test Report

We test each batch of our biotin powder in our own quality control lab, as well as third party labs such as SGS and Eurofins.

Testing: HPLC assay to check purity. Polarimetry to confirm optical rotation ( + 89° to + 93°). GC for residual solvents (benzene, toluene and Class 1/2 solvents from synthesis). ICP-MS for heavy metals. Full microbiological screening.

You can request a test report for a specific batch before placing your order. All production lots may be traced in the records.

D Biotin Powder Advantages

100% Active D-Isomer

No inactive L-biotin to dilute your formula. You get complete metabolic activity for every gramme, so you need less and more regular doses.

High Heat Stability

In dry conditions the crystalline matrix can resist temperatures up to 100°C. This is important for feed pelleting procedures and for tablet compression where heat cannot be avoided.

Ultra-Low Contaminant Level

You can use it across product categories, because with ash content <0.1% and heavy metals <2 ppm, this product is food-grade and pharmaceutical-grade.

Precision Dose Support

The suggested daily dose is in the microgram range hence we also have 1% and 2% dilutions on maltodextrin carriers. These triturations enhance the content consistency for big batch scale blending.

Clean Label Friendly

Animal-free raw materials Made by chemical synthesis GMO-free organisms Vegan, Non-GMO, Kosher, Halal label claims.

D Biotin Powder Application

Animal Nutrition & Feed Additives

Biotin powder is commonly used for the prevention of Fatty Liver and Kidney Syndrome (FLKS) in poultry, and to correct hoof keratosis in dairy cattle and pigs. Steam pelleting gives it thermal stability so the potency reaches the animal intact, enhancing reproductive success and lowering losses due to lameness.

Pharmaceutical and Nutraceutical Manufacturing

For use in B-complex pills, softgel capsules and hair-skin-nail supplements. For homogeneous blending to obtain content homogeneity at microgram level dosages, trituration is recommended. Suitable with high speed tablet compression machines.

Formulations of Cosmetic and Personal Care

For use as a conditioning agent in shampoos, serums and creams. Biotin has a low lipid solubility and so should be pre-dissolved in the aqueous phase or mixed with solubilizers to improve its penetration into keratin structure.

Production Process

The biotin powder of Shaanxi Hongda is produced by regulated chemical synthesis in 100,000-level purification workshop. The process consists of major stages:

Synthesis Crystallisation Filtration Drying Milling QC Testing Packaging

Each stage is tested for purity and contamination. Residual solvents are eliminated under established circumstances and confirmed by GC analysis. Final milling provides a homogenous white crystalline powder with uniform particle size and bulk density. It is packaged aseptically in double layer PE inner bags and fibre drum exterior packing.

FAQ

Q1. What is the difference between D-biotin and DL-biotin?

A: D-biotin is solely the biologically active type. DL-biotin is a 50/50 racemic combination, therefore half of it has no metabolic advantage. D-biotin is the right choice for accurate dosing, label states.

Q2: How stable is biotin powder during heating processing?

A: Stable in dry form to 100C for short periods. Avoid high-pH wet processing environments: Stability is reduced in very alkaline aqueous solutions.

Q3: Is the product light or oxygen sensitive?

A. It is stable under typical atmospheric conditions. Store in light-resistant, sealed containers away from moisture to prevent progressive loss of efficacy.

Q4: Why do you advocate 1% or 2% dilutions?

A. The effective dose is in the microgram range, and it is difficult to precisely weigh and spread pure 99% powder. Diluted triturations on carriers like maltodextrin allow uniform distribution in big batch manufacture.

Q5: Does your product support Vegan and Non-GMO claims?

A: Yeah. No animal derived raw materials or GMO organisms are used in the synthesis. The product is certified Vegan, Kosher and Halal to accommodate clean-label needs.

Q6: What kind of documentation do you supply for regulatory submission?

A: We give COA, MSDS, spec sheets, 3rd party SGS/Eurofins reports and certification documents. Custom forms of documentation available upon request.
