LIPOXOL 3350 MED flakes Features & Benefits
Applications & Uses
- LIPOXOL MED grades are widely used excipients in a variety of pharmaceutical preparations. The liquid LIPOXOL MED grades are used as solvent, solubilizer and viscosity regulator in liquid pharmaceutical formulations. Mixtures of liquid and solid LIPOXOL MED grades are used as ointment bases. Solid LIPOXOL MED grades are used as suppository bases and act as binders and plasticizers for tablets (Handbook of Pharmaceutical Excipients, 2nd edition, p. 355 ff.). LIPOXOL 3350 MED and LIPOXOL 4000 MED are used as active ingredients in medicinal products, i.e. laxatives.
- The liquid LIPOXOL MED grades are readily soluble in water and miscible in all portions with other grades. With increasing molecular weight the solubility in water is slightly lowered. However, even the solubility of LIPOXOL 8000 MED in water is more than 500 g/l. The LIPOXOL MED grades are (according to their molecular weight) soluble in polar organic solvents like alcohols, benzene, glycerine glycol and chloroform. No or slight solubility is given in aliphatic hydrocarbons, ethers and fats. LIPOXOL MED grades can be used to enhance the aqueous solubility or dissolution characteristics of poorly soluble compounds.
- Due to their hygroscopicity the LIPOXOL MED grades are used as moisturizers which provide soft and readily dispersible ointment bases causing a liquid flow opposed to the resorption. On skin they show a cleansing and drying effect. Therefore LIPOXOL MED containing ointments can be used to treat wet and inflamed wounds.
- Liquid LIPOXOL MED grades are used as water miscible solvents dedicated for dissolution of actives in soft gelatine capsules. Aqueous solutions of LIPOXOL MED grades can be either used as suspending agents or to adjust the viscosity and consistency of pharmaceutical products. When used in combination with emulsifiers LIPOXOL MED grades can act as emulsion stabilizers.
- In solid dosage forms LIPOXOL 3350 MED, 4000 MED, 6000 MED and 8000 MED enhance the effectiveness of tablet binders and provide plasticity to granules. There are a number of techniques producing tablets containing LIPOXOL MED grades. When used for thermoplastic granulation a mixture of powdered components with 10-15 % LIPOXOL 6000 MED is heated to 70-75°C resulting in a paste. Whilst cooling and stirring granules are formed. Solid LIPOXOL MED grades can be used for film coating of tablets or as polishing or softener materials for film tablets.
