Frequently Asked Questions
Q: What is the difference between DL-Tartaric Acid and L-Tartaric Acid?
A: DL-Tartaric Acid is a racemic mixture containing equal parts of D- and L-isomers, while L-Tartaric Acid is the naturally occurring enantiomer. DL-form has no optical rotation and different solubility characteristics.
Q: Is DL-Tartaric Acid safe for food applications?
A: Yes, it is Generally Recognized As Safe (GRAS) by FDA and approved for use in food products worldwide. It has E number E334 in Europe.
Q: What packaging options are available?
A: We offer 25kg bags, 500kg bulk bags, and custom packaging. All packaging is moisture-proof and suitable for international shipping.
Q: What is the shelf life?
A: Properly stored in original packaging, DL-Tartaric Acid has a shelf life of 24 months from production date.
Q: Do you provide samples?
A: Yes, we provide free samples for qualified customers for testing and evaluation purposes.
Q: Can you customize particle size?
A: Yes, we can provide various particle sizes from fine powder to granular forms based on your application requirements.
Q: What documentation do you provide?
A: We provide Certificate of Analysis, MSDS, and other required documentation for regulatory compliance in your region.
Q: What are your payment terms?
A: We accept T/T, L/C, and other secure payment methods with flexible terms for established customers.
