Other pharmaceutical applications
Gelatin is considered a highly versatile product due to its properties, which include its ability to act as a colloid or a binding agent, or to form flexible plasticized or hard films. As it is able to doing many things competently, consequently, it is recognized as one of the most popular raw materials for pharmaceutical products.
Wound healing products can also be gelatin-based. They stimulate the healing process of all types of wounds and in doing so help in terms of reducing the formation of scars.
Tablets are one of the most popular solid dosage forms in pharmaceuticals and food supplements. Gelatin can be used either as an adhesive binder or in the coating for the tablets. It also improves both the stability and the release of the active ingredient. Meanwhile, gelatin can provide part of the matrix in lyophilized tablets. Furthermore, oval-shaped tablets can be coated with a gelatin layer to facilitate swallowing, which is called a caplet.
Colostomy products also use gelatin as an adhesive. This enables the colostomy bags to stick to the body of the patient in order to absorb the residual skin moisture and form a closed system.
Gelatin plays a role as a barrier against oxygen and light while at the same time working as an emulsifying agent in the phase of the aqueous gelatin solution, as well as in vitamins A and E. These are oil-based and with the help of gelatin the vitamins can be converted into easily dispersible, free-flowing powders via a specific spray drying process.
