Dissolution Study of Salt of Long Chain Fatty Acids (Soap Scum) in Surfactant Solutions. Part I: Equilibrium Dissolution

Dissolution of calcium salt of a long chain fatty acid or soap scum is a major challenge for hard surface cleaners since soap scum forms when soap is exposed to hard water and has very low water solubility. In this paper, the aqueous equilibrium solubility of calcium octadecanoate (or calcium stearate) was measured as a function of pH as well as chelating agent (ethylenediaminetetraacetate disodium salt) and surfactant concentrations. Anionic, nonionic, and amphoteric surfactants were studied. The highest soap scum solubility was observed at high pH with an amphoteric surfactant. Under this condition, the chelant effectively binds calcium, and the stearate anion forms mixed micelles well with the amphoteric surfactant, which is in zwitterionic form at high pH.

Dissolution of Soap Scum by Surfactant Part I: Effects of Chelant and Type of Soap Scum

The equilibrium solubilities of two model soap scums [calcium stearate and magnesium stearate: Ca(C₁₈)₂ and Mg(C₁₈)₂] were measured in aqueous solutions containing three different types of surfactants: methyl ester sulfonate (MES) as an anionic; alcohol ethoxylate (EO9) as a nonionic; and dimethyldodecylamine oxide (DDAO) as an amphoteric with and without a chelating agent [disodium ethylenediaminetetraacetate (Na₂EDTA)]. The solubility of calcium soap scum was generally higher than that of magnesium soap scum, the exception being some DDAO systems. The use of the DDAO surfactant with the Na₂EDTA chelating agent at high pH gives the highest solubilities of both studied soap scums. The soap scum solubility is on the order of 2,000 times that in water at high pH. The DDAO is the most effective surfactant under all conditions. The MES is more effective than the EO9 at low pH with the opposite trend observed at high pH. The synergism from added chelant is generally greater at higher pH and is greatest for DDAO followed by EO9.

Liquid laundry detergents based on soap andα-sulfo methyl esters

It is well known that soap is one of the most effective cleaning agents in soft water. However, soap is equally notorious for some of its deficiencies, especially formation of soap scum due to the precipitation of calcium and magnesium soaps in hard water, low solubility in water, poor cleaning in cold water, greying of fabrics and dulling of hard surfaces such as ceramic tiles. Attributes of soap that should not be overlooked, especially in today’s environment, include an abundant and natural raw material supply (vegetable oils and fats) and excellent human and environmental safety profiles that are superior to most synthetic surfactants.

Two new stable polybrominated salicylanilides for antibacterial use in soap and detergent products

The versatility of two brominated salicylanilides as antiseptic agents and germicides in soap and detergent products for use on skin, hair, hard sur-faces and in fabrics is discussed. Both preparations show stability at elevated temp and pressure and compatibility with many surfactant vehicles. They are free of primary irritation and sensitization, including sunlight-induced irritation. A mixture of di- and tribromosalicylanilide is currently being used in toilet bars, shampoos, laundry products, disinfectant sprays and multi-purpose disinfectant products. The substantivity to fabrics is further characterized by stability to heat and hydrolysis by alkalinity. Essentially pure 3,4′,5 tribromosalicylanilide is resistant to discoloration, making it particularly suitable for use in white and pastel colored toilet bars. It has excellent substantivity to skin and provides long-lasting action against odor-causing and pathogenic bacteria.

Soap and lime soap dispersants

In recent decades, soap has largely been replaced by petrochemicals and polyphosphates as the major components of laundry detergents in the U.S. Currently, the use of soap is primarily confined to the toilet soap bar field, and technological advances here have been mainly in processing. In view of the rising costs and increasing scarcity of petrochemicals and polyphosphates, tallow, a replenishable, inexpensive agricultural by-product, was examined as an alternate raw material. Tallow soap has a long history of efficacy and safety but suffers from poor performance in hard water and insolubility in cold water. It has now been shown that the performance of soaps can be drastically improved in cold water solubility and in hard water detergency by the addition to the soap of lime soap dispersing agents (LSD A). These are anionic or amphoteric surfactants possessing one or more bulky polar groups. These soap-LSDA combinations form mixed micelles in water and essentially take on the surface active characteristics of a single anionic surfactant. Soap-LSDA combinations wash well in hard water without curd formation; they can be “built” with various materials such as phosphates and trisodium nitrilotriacetate (NTA) to enhance detergency. Soap-LSDA combinations equal the conventional detergents in every performance respect and undergo biodegradation more readily and completely.
