Propylparaben Sodium
Propylparaben sodium is used as an antimicrobial or antifungal preservative in oral pharmaceuticals and in many water-based cosmetics. It is generally used in combination with other paraben esters.
Phosphoric Acid
Phosphoric acid is widely used as an acidifying agent in a variety of pharmaceutical formulations. It is used in pharmaceutical products as part of a buffer system when combined with a phosphate salt such as sodium phosphate, monobasic or dibasic. It is also widely used in food preparations as an acidulant, flavor, and synergistic antioxidant […]
Docusate Sodium
Docusate sodium and docusate salts are widely used as anionic surfactants in pharmaceutical formulations. Docusate sodium is mainly used in capsule and direct-compression tablet formulations to assist in wetting and dissolution. Docusate salts are also used in oral formulations as laxatives and fecal softeners.
Sodium Phosphate, Dibasic
Dibasic sodium phosphate is used in a wide variety of pharmaceutical formulations as a buffering agent and as a sequestering agent. Therapeutically, dibasic sodium phosphate is used as a mild laxative and in the treatment of hypophosphatemia. Dibasic sodium phosphate is also used in food products; for example as an emulsifier in processed cheese.
Edetate Calcium Disodium
Edetic acid and edetate salts are used in pharmaceutical formulations, cosmetics, and foods as chelating agents. They form stable water-soluble complexes (chelates) with alkaline earth and heavy metal ions. The chelated form has few of the properties of the free ion, and for this reason chelating agents are often described as ‘removing’ ions from solution; […]
Metacresol
Thymol is a phenolic antiseptic, which has antibacterial and antifungal activity. It has disinfectant, flavoring agent, skin penetrant, therapeutic agent. Properties.
Sodium Hydroxide
Sodium hydroxide is widely used in pharmaceutical formulations to adjust the pH of solutions.(1) It can also be used to react with weak acids to form salts.
Potassium Bicarbonate
As an excipient, potassium bicarbonate is generally used in formulations as a source of carbon dioxide in effervescent preparations, at concentrations of 25–50% w/w. It is of particular use in formulations where sodium bicarbonate is unsuitable.
Alpha.-Tocopherol
Alpha tocopherol is primarily recognized as a source of vitamin E, and the commercially available materials and specifications reflect this purpose. While alpha tocopherol also exhibits antioxidant properties, the beta, delta, and gamma tocopherols are considered to be more effective as antioxidants. Alpha-tocopherol is a highly lipophilic compound, and is an excellent solvent for many […]
Simethicone
The main use of simethicone as an excipient is as an antifoaming agent in pharmaceutical manufacturing processes, for which 1–50 ppm is used.
