The mangosteen we use is a dry extract (es) but not glycolic, because of the dry extract is to all effects qualitatively superior in terms of concentration in active ingredient. In fact, ES is obtained with the dried drug that is immersed in water and alcohol, until it releases active ingredients. Then the liquid is evaporated and the dry extract is obtained. The dry remaining residue contains all the active compounds of the plant drug. To prepare a gram of dry extract of a vegetable substance is sometimes necessary to use up to 1 KG of raw material (depending on the starting material). The dry extract is one of the most recommended pharmaceutical forms because it has the largest concentration of pure substances of a plant or plant part. For this reason it has a high number of active principles and a greater effect: on average is about a 20-30 times more concentrated compared to other extracts. A most common type for the ‘cosmetic use is the’ Glycolic Extract (EG), even for its low production cost. The EG are very comfortable in cosmetic preparing as they are well suited to the various emulsions / formulations. but they have a drawback compared to the ES, because they are the poorest of active principle.
