Starch hydroxypropylated

Enzymes to degrade crosslinked hydroxypropylated starch derivative and xanthan gum polymer systems are available [158,1246]. Specific enzymes are efficient in reducing the near wellbore damage induced by the starch polymer to eventually return permeabilities to the range of 80% to 98% without the use of acid systems.

Early soil-release agents, applied particularly to resin-finished cellulosic goods, were water-soluble polymers, many being related to thickeners (section 10.8) such as starch, hydroxypropyl starch, sodium carboxymethylcellulose, methylcellulose, hydroxyethyl-cellulose, alginates, poly(vinyl alcohol) and poly(vinylpyrrolidone). These functioned essentially as temporary barriers and preferential reservoirs for soil, which was thus easily removed along with the finish in subsequent washing, when they then helped to minimise...

Hydroxypropyl starch is a derivative of natural starch it is described in the JPE 2004 as a hydroxypropyl ether of corn starch. [Pg.344]

Hydroxypropyl starch is stable at high humidity and is considered to be inert under normal conditions. It is stable in emulsion systems at pH 3-9. [Pg.344]

Hydroxypropyl starch is produced industrially from natural starch, using propylene oxide as the modifying reagent in the presence of alkali, adding hydroxypropyl (CH(OH)CH2CH3) groups at the OH positions by an ether linkage. [Pg.344]

Hydroxypropyl starch is widely used in cosmetics and food products. It is also used in oral pharmaceutical formulations. The WHO has set an acceptable daily intake for hydroxypropyl starch at not limited since it was well tolerated on oral... [Pg.344]

Hydroxypropyl starch is a modified starch and has been used in combination with carrageenan in the production of soft capsules. " Hydroxypropyl starch has been used experimentally in hydrophilic matrices, where it was shown to be an effective matrix for tablets designed for controlled-release drug delivery systems. It has also been used experimentally in the production of hydrophilic matrices by direct compression. ... [Pg.344]

Although it is not currently included in the pharmacopeias, a specification for hydroxypropyl starch is included in the Japanese Pharmaceutical Excipients (JPE) 2004 see Table I. Hydroxypropyl starch is compatible with cationic ingredients (monovalent, divalent), oils, emollients, and silicone. [Pg.344]
