Fatty acid esters of isethionic acid (such as sodium lauroyl isethionate and sodium cocoyl isethionate) are used as biodegradable anionic surfactants. [3] These materials are much milder to skin that other sulfate based surfactants (i.e. sodium lauryl sulfate) [4] making them popular for use in make-up, shampoos and detergent bars including those made by Dove.
They are non-toxic and readily biodegradable. [ citation needed ] However, in contrast to the taurides , they are not long-term stable outside a pH range of 5 to 8. [ citation needed ] Isethionates are used in solid soaps (so-called syndet bars) and in other personal care products such as lotions, washing and shower gels, shampoos, liquid soaps ...
Most natural shampoos are made with natural and organic ingredients that are biodegradable and sustainable. Natural hair care brands go out of their way to ensure that their packaging is ...
Decyl glucoside is a mild non-ionic surfactant used in cosmetic formularies, [1] including baby shampoo and in products for individuals with a sensitive skin. Many natural personal care companies use this cleanser because it is plant-derived, biodegradable, and gentle for all hair types. Decyl glucoside was invented by Robert Prairie in 1934.
The first known use of biodegradable in a biological context was in 1959 when it was employed to describe the breakdown of material into innocuous components by microorganisms. [57] Now biodegradable is commonly associated with environmentally friendly products that are part of the earth's innate cycles like the carbon cycle and capable of ...
Detergents. A detergent is a surfactant or a mixture of surfactants with cleansing properties when in dilute solutions. [1] There are a large variety of detergents, a common family being the alkylbenzene sulfonates, which are soap-like compounds that are more soluble in hard water, because the polar sulfonate (of detergents) is less likely than the polar carboxylate (of soap) to bind to ...
Biodegradable additives can convert the plastic degradation process to one of biodegradation. Instead of being degraded simply by environmental factors, such as sunlight ( photo-oxidation ) or heat ( thermal degradation ), biodegradable additives allow polymers to be degraded by microorganisms and bacteria through direct or indirect attack.
The advantage of using phosphates in a consumer laundry detergent or dishwashing detergent is that they make detergents more efficient by chelating calcium and magnesium ions. [1] The disadvantage of using phosphates is that they remain in wastewater and eventually make their way to a natural body of water. [ 1 ]
