ABSTRACT
In the past decade, the demand for natural and eco-friendly products has been growing. Natural polymers, with emphasis on starch, are a valuable option to comply with this green request, whilst creating products with the desired sensorial attributes. Minor components of starch include lipids, proteins, and minerals. Starches, in particular cereal starches, contain inner lipids in the form of free fatty acids and lysophospholipids. Modified starch has been developed to fulfill pharmaceutical industry needs. Starch is the most abundant storage reserve of carbohydrates in plants. It is found in many different plant organs, including seed, fruits, tubers and roots. The skin is an important part of the integumentary system, as it protects the body from external damage. Delivery systems for topical drug therapy aim to produce the desired therapeutic effect at specific sites in the epidermal tissue. Properties of starch and its advantages as a pharmaceutical excipient are well studied, and it is widely used in technology of oral formulations.
