A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Anhydrous Lactose (CAS 63-42-3) is the water-free crystalline form of lactose, a disaccharide of galactose and glucose, supplied as a free-flowing powder. It is used as a diluent and filler-binder in pharmaceutical tablets and capsules, including direct-compression formulations, and as an ingredient in food products.
Frequently Asked Questions
What is anhydrous lactose used for?
Anhydrous Lactose (CAS 63-42-3) is the water-free crystalline form of lactose, used as a diluent and filler-binder in pharmaceutical tablets and capsules, including direct-compression formulations, and as a carbohydrate ingredient in food products. RawSource supplies NF-grade DCL-21 as a free-flowing powder.
What is the difference between lactose monohydrate and lactose anhydrous?
Lactose monohydrate contains one molecule of water of crystallization, while anhydrous lactose is the water-free form. Anhydrous grades like DCL-21 are favored in direct-compression and moisture-sensitive formulations for their flow and low water content; monohydrate is common in wet granulation.
Does anhydrous lactose contain dairy?
Lactose is the disaccharide sugar of milk, so it is dairy-derived (from galactose and glucose). RawSource supplies it as a purified NF-grade carbohydrate ingredient; specify any allergen-documentation requirements on your RFQ.
What does DCL-21 mean for anhydrous lactose?
DCL-21 is a directly-compressible grade designation for anhydrous lactose engineered for tableting performance (flow and compactibility). Related directly-compressible designations differ in particle engineering; confirm the exact grade you require on your RFQ, as substitutions affect compression behavior.
What is the HS code and bulk packaging for anhydrous lactose NF?
Anhydrous Lactose classifies under HS 1702.11 (lactose 99% or more, expressed as anhydrous on dry matter). RawSource ships it in bulk bags and palletized packaging to pharmaceutical and food manufacturers, with NF Certificate of Analysis and SDS on request. Contact us for a bulk quote.
