In formulating liquid detergent products with LAS, the carbon chain distribution, phenyl isomer distribution, and DATS level can all contribute to the solubility and viscosity characteristics. Hydrotrope requirements for isotropic liquid detergents can vary widely for different types of commercial LAS.

The applications of alcohol sulfates in consumer products depend on the alkyl chain and in some cases on the cation. Alcohol sulfates with alkyl chains 8 C1() are seldom used in consumer products except occasionally as hydrotropes in liquid detergent formulations. However, alcohol sulfates in the range C10-C18 are used in many commonly used formulations although other surfactants are generally added to enhance their properties. In some of these applications, particularly in shampoos, they compete with alcohol ether sulfates of the same alkyl chain distribution. The pattern of use of alcohol sulfates or alcohol ether sulfates in formulations varies with consumer personal care and laundry washing preferences in different cultural areas of the world.

Choose a builder and its amount depending on the aqueous solubility of the builder in the product besides its chelating power. For instance, do not use insoluble zeolites in unstructured liquid detergents. 

Consider using preservatives in detergent products containing biodegradable raw materials with a neutral pH, especially low concentration liquid detergents. 

Liquid detergents are used primarily for dishwashing or shampoos and usually are composed of highly water-soluble materials such as the nonionics, the lower molecular weight alkyl aryl sulfonates, the organic amine sulfonates, or mixtures of the same. Active product concentrations in water or an alcohol solvent will vary from 5 to 95%. 

Figure 14.24a), have been developed. Other common categories of degradable plastics include synthetic biodegradable plastics which are broken down by bacteria, as well as plastics which dissolve in water (Figure 14.24b). The property that allows plastic to dissolve in water has been used in relatively new products, including soluble capsules containing liquid detergent. However, the vast majority of polymers are still non-biodegradable.

Dodecylbenzene for the production of the alkyl aryl sulfonate type of detergent came later and was soon an important product of those petroleum refineries going into the petrochemical field. The non-ionic detergents followed when low-sudsing liquid detergents began to show their value. 

Heavy-Duty Liquid Detergents. The ease of incorporation and affinity of FWAs are crucial in such formulations. Heavy-duty liquid detergents can also be employed as prespotters that are applied in concentrated form to heavily soiled areas before the normal washing process. Bright spots can be formed, especially on colored fabrics, due to washing out of the color they are intensified by the fluorescence of the locally high FWA concentration. For this reason, FWAs have been developed which cause less pronounced spotting that cannot be seen. The main products in use are 10 and 21 [143],... 

On the other hand, as production of liquid detergents, either heavy- or light-duty, increases, alcohols with shorter carbon chains become important because of their good liquidities and high solubilities. In fact, this tendency has already appeared in some commercial products.
