Aug 03, 2010· The makers of Murphy's soap make a big deal about using mostly all natural ingredients and their potassium hydroxide must be reacted with the oils or thee is no soap. This reaction of fatty acids and potassium hydroxide produces POTASSIUM SALTS OF FATTY ACIDS.
Soap salts are either potassium or ammonium salts of fatty acids. These products are suitable for moss control in grass and on roofs or other structures such as decks and sidewalks. Moss-killing products with soap salts are noncorrosive, will not stain most surfaces and will not harm vegetation.
Its claims include killing mites, earwigs, flea beetles, aphids, cabbageworms, leafhoppers, mealy bugs and other insects upon contact. This product contains 25 percent of potassium salts of fatty acids that are derived from neem seed oil and 75 percent inert ingredients.
The process in which a solution of known concentration is used to find the concentration of a second solution is called _____ Soaps Substances made when sodium or potassium hydroxide reacts with fatty acids are called ______
Potassium salts of fatty acids are commonly called soap salts. They are used as insecticides, herbicides, fungicides, and algaecides. The first pesticide product containing soap salts was registered for use in 1947 (1). Potassium salts of fatty acids are produced by adding potassium hydroxide to fatty acids found in animal fats and in plant oils.
The FDA defines salts of fatty acids as multipurpose food additives that may be directly added to food for human consumption (1). Potassium salts are also used as insecticides, herbicides, fungicides, and algaecides (2).
Potassium salts of fatty acids General Information: This product is non-staining on most surfaces and is for use on decks, fences, roofs and lawns. This product will supposedly not harm bordering plants. This product is made from biodegradable fatty acids. It is water based. non-corrosive to metals, and contains no zinc or iron.
In the European Union, fatty acid potassium salts are registered and allowed as insecticide at a 2% concentration. Insecticidal soap is most effective if it is dissolved in soft water, since the fatty acids in soap tend to precipitate in hard water, thereby reducing the effectivity. Insecticidal soap is sold commercially for aphid control.
