Purpose: The present research was performed to evaluate the effect of food thickeners on bitterness and dissolution bitter drugs when co-administered patients with dysphagia. Methods: Amlodipine besilate (AMPB) powder used as a model drug. Starch- xanthan gum-based were examined, swallowing-aid jelly reference. line-spread test (LST), texture prolife analysis (TPA) done firstly. In related AMPB...

Water plays a key role in mineral processing plants. In order to process one ton of ore, 2.5 ton water is needed. Thickeners are commonly used for dewatering and recovering the water in most mineral processing plants. The underflow pulp density is increased by the sedimentation of particles and a clear water is then recovered from the overflow. One of the issues related to using the process wat...

An environmental friendly palm-grease has already been formulated from modified RBDPO (Refined Bleach Deodorized Palm Oil) as base oil and lithium soap as thickener. Such palm-grease is dedicated for general application and or equipment working in areas where biodegradability is required such as in agriculture, forestry and coastal marine, recreation areas. The grease was manufactured via 4 ste...

A six-month repeated-dose dermal toxicity study fo11owed by a 30-day recovery test of hydrophobically modified hydroxypropyl methylcellulose (HM-HPMC), a new ceLlulose derivative used as a thickener for topical pharmaceuticals, was conducted using rats, Aqueous paste of HM-HPMC was applied to the skin ofrats once daily at dose levels up to 60 mg/kglday, which was the highest dose that could be ...

Abstract. The process of continuous sedimentation of particles in a liquid has often been predicted by means of operating charts and mass-balance considerations, where the underlying constitutive assumption is the one by Kynch. Much more complex operating charts (concentration-flux diagrams) can be obtained from a onedimensional model of an ideal continuous clarifier-thickener unit. The enginee...
