Blends of soap and 3 lime soap dispersants—the sulfated tallow alkanolamide (TAM), the coconut-oil-derived amido sulfobetaine (CAHSB) and the cocoamido betaine (CAB)—were formulated with 3 builders—sodium tripolyphosphate (STPP), trisodium nitr

Low pressure oxyethylation of RNHCOR CONHR or RCONHCH2CH2NHCOR does not occur below 100 C where R represents branched aliphatic groups and R’ is 0–4 methylene groups or -CH=CH-. These diamides add ethylene oxide at 140–170 C to give dark adduct

Amides and 2-alkyl-N-(2-hydroxyethyl)-imidazolines were converted into various types of sulfated or sulfonated amphoteric lime soap dispersants. The alkylimidazolines could be readily hydrolyzed to give amidoamines. The cyclized amphoteric surfactant

The precision of a standardized detergency test based on the use of a Tergotometer and U.S. Test Cloth was found at a concentration of 0.4 and 0.5%. At these concentrations, the standard deviation was 0.56% soil removal units, and precision at a 95%

This paper describes a standardized laboratory procedure for determining the fabric soil-removal efficiency of heavy-duty detergents. A careful analysis of machines, standard soil fabrics, operating times, and water hardness had led to the standardiz

In order to gain some insight into the correlation between chemical structure and surface active properties, a number of amphoteric surface active agents were synthesized. All of these compounds possessed both a quaternary ammonium group and an anion

Krafft point measurements were used to show that lime soap dispersing agents (LSDA) and soaps solu-bilize each other. Addition of as little as 5% soap to amphoteric LSDA of limited water solubility (high Krafft point) brought about a substantial lowe

The stock of a given soap may be estimated when the ratios of the fatty acids present are known. A new gas chromatographic procedure utilizing a novel automatic attenuator is presented. The samples are prepared by refluxing the soap with a methanolic
