Description

Witepsol CAS NO 12713-12-1 is a high-quality, semi-synthetic base material derived from vegetable oils, specifically engineered for use in pharmaceutical and cosmetic suppository formulations. Its primary value lies in its excellent melting behavior, stability, and compatibility with a wide range of active pharmaceutical ingredients (APIs), ensuring consistent and reliable drug delivery. This product is essential for manufacturers in the pharmaceutical, nutraceutical, and personal care industries who require a superior, non-irritating excipient for solid dosage forms.

Application

• Primary excipient in the manufacture of rectal and vaginal suppositories.
• Base material for pessaries and other solid, meltable drug delivery systems.
• Carrier for active ingredients in cosmetic sticks (e.g., deodorant, lip balm).
• Formulation component in veterinary suppositories and implants.
• Matrix for controlled-release and sustained-release suppository formulations.
• Used in the development and production of medicated lozenges and bougies.

Quality Control

Our Witepsol is produced and tested under strict quality management systems to meet the demanding requirements of pharmaceutical and cosmetic applications. Each batch is characterized for critical parameters such as melting point, solid fat content, and acid value to ensure batch-to-batch consistency and performance. Certificates of Analysis (COA) documenting compliance with relevant pharmacopoeial standards (e.g., EP, USP-NF) are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Protect from moisture and sources of heat to maintain its physical properties and prevent rancidity.
