Frequently Asked Questions
Q1: What's the difference between MSM 99.9% Standard, Tabletting, and Cosmetic grades?
All three grades are 99.9% pure MSM. The differences are in particle size, residual impurity profile, and GMP controls. Tabletting grade has optimized particle size for compression; cosmetic grade meets additional purity standards for topical use.
Q2: What is MSM?
MSM (Methylsulfonylmethane) is a naturally occurring organic sulfur compound found in fruits, vegetables, grains, and animal tissues. It is commercially produced via DMSO oxidation for supplement and skincare applications.
Q3: Can MSM be combined with other ingredients?
MSM is commonly combined with Glucosamine, Chondroitin, and Hyaluronic Acid in joint health formulations. In skincare, it is combined with soothing botanicals (Centella, Aloe). We recommend consulting with your formulation team.
Q4: What's the regulatory status in the EU?
MSM is permitted as a food supplement ingredient in the EU. Specific regulatory status depends on intended application and labeling.
Q5: How is MSM purity measured?
MSM purity is quantified via Gas Chromatography (GC) or HPLC per USP / industry-standard methods.
Q6: What's the typical MOQ?
Standard MOQ is 25 kg. Smaller quantities (5-10 kg) are available for evaluation.
Q7: Do you offer custom specifications?
Yes. Custom specifications (e.g., specific particle size, impurity profile, packaging) can be discussed with our coordination team.
Q8: What documentation is available?
Standard documentation includes COA, MSDS, allergen statement, Non-GMO statement. Additional documentation available upon request from production partners.
