Extraction of Active ingredients form tamarind fruit and incorporation it is due the develop of a personal care product

Abstract

Tamarind ( Tamarindus indica ) a large to very large evergreen tree up to 30 m in height with dark grey bark having longitudinal Fissures and deep cracks, leaves paripinnate up to 15 cm long, rachis slender, channeled leaflets 10-20 pairs, fruits pods, brownish ash coloured. Fruit contains tartaric acid, citric, acid, malic acid and potassium bitartarate and traces of Oxalic acid, kernel, polysaccharides. The fruits are sour, sweet, refrigerant, digestive, carminative, laxative, anti-scorbutic, anti- septic , ophthalmic and febrifuge tamarind is also used to the face for antifreckle and anti-aging purposes, Currently, Tamarind extract is used as a ingredient in body cleansing products for adjusting skin acidity condition, and antiseptic antiallergy and skin tightening purposes such as anti-aging ,anti-wrinkle and maintain the skin’s elasticity due to the inhibition of proteolytic and hydrolytic enzymes that destroy the collagen, elastic and hyarulonic acid in the skin, which protect skin from sun damage. A cosmetic patch containing tamarind fruit extract was formulated and developed by blending tow types of natural polymers, chitosarn with molecular weight of 100 000 and starch such as com, potato or tapioca starch. The physicochemical characteristics, flexibility, colour, transparency, integrity, gloss, water sorption and bioadhesion property and the stability of the patch without tamarind content were investigated. Nearly 50% of the tartaric acid is in the combined form mainly as potassium bitartrate and to a small extent as calcium tratrate, which is insoluble in cold water, Therefore, cold water extract of the pulp contains only a part of the available tartaric acid and hence hot water is to be used to extract the total acids in the pulp. About 2% of other acids (malic acid, citric acid, quinic acid, oxalic acid and succinic acid) are also present in the pulp.
