Sulfonation and sulfation processes are utilized in the production of wateT-soluble anionic surfactants as principal ingredients in formulated light-duty and heavy-duty detergents, liquid hand cleansers, general household and personal care products, and dental care products. Other commercially significant product applications include emulsifiers, lube additives, sweeteners, pesticides, medicinals. ion-exchange resins, dyes and pigments.

Heavy-duty detergents. Heavy-duty detergents include those detergent products suited to all types of washing and cleaning at all wash temperatures. They are offered in both powder and liquid forms and huge differences are found from one formulation to another. The powdered formulations generally do not contain solvents, and hence, only the liquid...

Nonionic surfactants are increasingly popular active ingredients for liquid heavy duty laundry detergent formulations. The majority of nonionic surfactants are polyoxyethylene or polyoxypropylene derivatives of alkyl-phenol, fatty acids, alcohols, and amides. It has been estimated that approximately one ethylene oxide unit is required to solubilize each methylene unit. Thus, by changing the ratio of ethylene oxide to fatty acid, the nature of the surfactant can be modified from an...

Because of its superior solubility characteristics, a high 2-phenyl LAS (with an alkyl chain length average of 11.4) was the preferred type. The detergency performance of one LAS/AE type of formulation was discussed previously (see Figs. 12 and 13). Early commercial heavy-duty liquid (HDL) formulations were built with phosphate, but since 1979 almost all U.S. HDLs have been formulated without phosphate. 

C in a Terg-o-Tometer. They tested commercial AOS, SAS, AS, and LAS detergents in two formulations one contains surfactant (25%) and sodium sulfate (75%) and is called a light-duty dishwash formulation. The other one contains surfactant (25%), sodium tripolyphosphate (35%), sodium silicate (8%), carboxymethylcellulose (1%), and sodium sulfate (31%), and is called a heavy-duty dishwash liquid. The results in Table 26 show that the AOS-containing formulations have superior performance, followed by SAS, AS, and LAS.
