Identification & Functionality

LIPOXOL 1500 MED Features & Benefits

Applications & Uses

Recommended Uses & Known Applications
  • 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.
  • 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. 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.
