Aqueous-based flowables

The Preparation of Aqueous-Based Flowables Ranging the Sample Size from Sub-Gram to Several Gallons... 

This paper will discuss the evaluation of several wet milling systems for providing precisely controlled (percent a.i., particle size, etc.) aqueous base flowables in a wide range of sample sizes. Included will be data on grind parameters (i.e., grind time vs. grind media type and charge) for the Crescent Dental Mills, as well as the. 01,... 

Evaluations have currently been made only on aqueous based flowables however, the methodology should be applicable to other suspension systems such as paints, coal/oil -slurries, etc. 

In addition, a new type of new biocide (designated FIBCIDE-KF), this time a water-based flowable product in which the inclusion complex (FIBCIDE-K58) has been ground into fine particles of 10 xm or less, in an aqueous solvent, has been manufactured using the process shown in Figure 8 [6],... 

While minimization possibilities are being investigated, substitutions should also be considered as an alternative or companion concept that is, safer materials should be used in place of hazardous ones. This can be accomplished by using alternative chemistry that allows the use of less hazardous materials or less severe processing conditions. When possible, toxic or flammable solvents should be replaced with less hazardous solvents (for example, water-based paints and adhesives and aqueous or dry flowable formulations for agricultural chemicals). 

Aqueous solutions of dimer amidopropyl betaine are highly viscous, and are typically non-flowable above a betaine actives concentration of 5 wt%. They display interesting rheological phenomena (25). To achieve higher concentrations for shipment of this Gemini betaine, mixtures with cocamidopropyl betaine can be made. On this basis, concentrations of 25 wt% active matter are achievable. Dimer amidopropyl betaine shows an increased substantivity, compared to cocamidopropyl betaine, on fibres and is a very effective irritancy miti-gant in anionic-surfactant-based systems. 

The RD 1336 process leads to a SA with relatively low bulk density. Technologies leading to a product with not only good flowability but also higher bulk density are based on the modification of the RD 1336 process. They differ from each other rady in partial technological steps as aU of them are based on increasing the solubility of silver azide in aqueous medium by addition of other complex-forming substances such as ammonia, pyridine, cyanides, thiosulfates, thiourea, etc. [69,95]. 

AMICAL Flowable is a water based liquid formulation of AMICAL (diiodomethyl-p-tolyl sulfone). As such, AMICAL Flow-able provides the same mildew and algacidal protection of polymeric systems as AMICAL 48 and AMICAL 50 with superior dispersing characteristics when used in an aqueous system. AMICAL Flowable contains 40% active ingredient by weight and efficacy testing indicates enhanced mildewcidal protection when compared to AMICAL 48, and water is used as the carrier.
