Detergency test

Grayness of a fabric swatch is not directly proportional to its content of black pigment (or artificial sod). A basic formula relating reflectance to the pigment content or concentration can be appHed to the evaluation of detergency test swatches (51,99—101). In simple form, an adaptation of the Kubelka-Munk equation, it states that the quantity (1 — i ) /2R (where R is the fraction of light reflected from the sample) is a linear function of the sod content of the sample. 

AOS at this proportion the micelle promotion tendency of AOS in the mixture is clearly optimal. At this composition, the authors have also observed a minimum in the surface tension vs. composition plot, and maximum performance benefits in detergency tests (see below). 

A great number of nonionic surfactants have been ethoxylated and subsequently reacted with P4O10. The acid phosphate esters from this reaction possess surface properties and detergency similar to the nonionic surface-active agents employed as reactants. Detergency tests and foam heights from the Ross-Miles method have been reported for a series of compounds. Various formulations for all-purpose cleaners are given as well [37,40,41,44,48].

Detergency in Dish Washing. Detergency tests for dish washing were conducted by the Modified Leenerts test prodecure. The test conditions and apparatus are shown in Table XV. 

In spite of their relatively high surface tension and poor wetting power, detergency tests show their better performance than LAS in non-built and comparable performance to LAS in built systems (Figure 39). 

Manoxol (sodium 2-actylosulfosuccinate) was the detergent tested. The results of Ma-noxol removal in Alj (804)3 coagulation and AAH adsorption processes was shown in Fig. 3. The data indicate that at low final Manoxol concentrations the adsorption process is more effective than the conventional coagulation process. 

All detergents tested were inhibitory, and the best results were obtained by mixing lyophilized enzyme with a benzene solution of the diglyceride, and evaporating off the solvent. 

Application of Microemulsions in Textile Cleaning Using Model Detergency Tests... 

The model detergency tests were carried out in a laboratory laundrometer LINITEST (Quarzlampen-Gesellschaft mbH, Hanau). The bath ratio of the washing system was 5 1, i.e., 20 g of test fabric per 100 g of microemulsion. In comparative detergency tests with the standard detergent solution, the laundrometer box contained 10 g of test fabric and 200 g of detergent solution (bath ratio 20 1). The test fabrics were submitted for 20 min to the main washing process at constant temperature. Afterwards they were rinsed three times for 10 min at the same temperature in 200 g of distilled water and dried for at least several hours at room temperature.
