Detergent types

Apparently a negative AP with Q < 90° can be found for particular pore geometries [53]. A different type of water repellency is desired to prevent the deterioration of blacktop roads consisting of crushed rock coated with bituminous materials. Here the problem is that water tends to spread into the stone-oil interface, detaching the aggregate from its binder [54]. No entirely satisfactory solution has been found, although various detergent-type additives have been found to help. Much more study of the problem is needed. 

The adsorption of detergent-type molecules on fabrics and at the solid-solution interface in general shows a complexity that might be mentioned briefly. Some fairly characteristic data are shown in Fig. XlIl-15 [242]. There is a break at point A, marking a sudden increase in slope, followed by a maximum in the amount adsorbed. The problem is that if such data represent true equilibrium in a two-component system, it is possible to argue a second law violation (note Problem Xni-14) (although see Ref. 243).

Wear scar (ASTM D4172 method four ball wear test). The antiwear performance was evaluated by the diameters of the wear scars in four-ball wear tests. The borate-detergent RMs showed better anti wear performance as compared with those of the carbonate-detergent RMs. Interestingly, the antiwear performance was dependent on the detergent type in the case of carbonate-... 

Bile salts are substances derived from sterols, which make up a substantial part of the solid matter in bile and which play a central role in lipid absorption, by virtue of their surface-active properties. The structure and properties of these salts have been reviewed by Haslewood (305) and Heaton (316). Bile salts essentially have molecules of detergent type hydrocarbon, with a fat-dissolving part and a polar, water-attracting part. The fat-dissolving part consists of the bulk of the steroid nucleus. The hydroxyl groups are so distributed that hydration can readily take place the remainder of the molecule will dissolve the fatty phase. Emulsification of fat/water complexes can thus occur easily. The terms bile acid and bile salt are used somewhat interchangeably in the literature. 

In the following sections, the major characteristics of the single interfacial processes of the washing process are summarised, concentrating on the more general features applicable to different detergent types. 

Before execution of the cleaning validation, the cleaning procedures should be in the form of approved standard operating procedures (SOPs). These procedures should be detailed enough to be reproducible. Parameters such as detergent type, detergent concentration, exposure time, rinse temperature/rinse time, and water pressure/flow rate should be included in the procedure. The final rinse is usually performed with water for injection (WFI). The production operators should be trained in these procedures and their training should be documented. 

The purpose of the study was to determine effective laundering procedures for decontaminating work jelght fabrics. The effect of fiber composition, pesticide formulation, detergent type, wash temperature, wash cycle procedures, laundry additives, and pesticide concentration on pesticide residue remaining after laundering were examined.

Primary alcohols are combustible materials and should be kept away from sources of ignition. The fire risk is considered moderate for detergent type alcohols with flash-points in the range 107-170 C. The vapour is combustible and can explode, therefore all equipment and tanks must be thoroughly cleaned and cleared as safe before welding is permitted.
