Prospect of Biologically Degradable Detergents

Nature or petrochemistry?-biologically degradable materials.

Naturally occurring polymers have been utilized for a long time as materials, however, their application as plastics has been restricted because of their limited thermoplastic processability. Recently, the microbial synthesis of polyesters directly from carbohydrate sources has attracted considerable attention. The industrial-scale production of poly(lactic acid) from lactic acid generated by f...

Action of Synthetic Detergents

The bactericidal and bacteriostatic actions of soaps have been recognized for many years. Detailed studies by Eggerth (1) on the germicidal action of soaps have shown the importance of such factors as length of hydrocarbon chain, chemical configuration, effect of hydrogen ion concentration, effect of serum, etc. Avery (2) demonstrated the selective germicidal action of soap on microorganisms, a...

Toxicity of Zeolite Containing Detergents

Introduction – Eutrophication is a serious problem This article compares the toxic effects of detergents of different types on aquatic organisms and is intended to outline the research comparing the toxicity of phosphate detergents with the toxicity of zeolite ones. Particular attention is given to the comparison of zeolitic and phosphate detergents. Phosphates are an important component in syn...

Divers’ Detergents Are Different

As anyone who has ever blown bubbles as or with a child knows, if you stop blowing before the sphere is complete, it collapses and disappears. The gas exchange surfaces of our lungs, the alveoli, are also highly curved, thin-walled, moist membranes that are open to the atmosphere. They too, would tend to go poof! and disappear, save for a mixture of phospholipids and proteins that lines the epi...
