- Challenges of Dissolution Methods Development for Soft . . .
Alkaline or acidic solutions are not good candidates for soft gelatin fill because they can cause hydrolysis and leakage of the gelatin shell unless their pH is adjusted to neutral [20]
- Soft gel encapsulation - Natural Products Insider
Soft gel capsules can also be entericly coated for certain applications Gelatin is derived mostly from collagen by thermal denaturing with the aid of diluted acid or alkali
- Gelatin Shell Material and Formulations for Softgels: An In . . .
Manufacturing Processes and the choice of gelatin type (acid vs alkaline) affect the final product’s quality and stability Plasticizers are crucial for making gelatin pliable and suitable for softgel capsules
- Investigation of the influence of pH on the properties and . . .
The gelatin blocks adjusted to more acidic and alkaline pH values (pH 2 and 12), formed softer blocks than those set at pH 5–10 It is believed that these changes with pH are a result of altered electronic environments in the gelatin network
- Gelatin and non-gelatin soft gel capsules: A review
The highest proportion of components in the soft capsule shells is gelatin, its origin is natural, and it is obtained from animal collagen (skin, tendons, bones, and cartilage) through acid hydrolysis and alkaline hydrolysis
- A REVIEW REPORT ON: COATING OF SOFT GELATIN CAPSULES
Materials found suitable include stearic acid, shellac, casein, cellulose acetate phthalate and natural and synthetic waxes; the basis of their use is their acid insolubility but alkaline solubility
- Pharmaceutical Formulation of Soft Gel Capsules
Depending on the nature of the liquid fill matrix, a wide range of gelatin shell compositions are available The gelatin used most commonly is alkali (or base) processed (type B) gelatin, which accounts for 40% of the wet molten gel mass Acid-processed gelatin of type A can also be utilised
