Environmental impact of cleaning agents
Environmental impacts of cleaning agents are the consequences of chemical compounds in cleaning products. Cleaning agents can be bioactive with consequences ranging from mild to severe. developmental and endocrine disruptors have been linked to cleaning agents. Green cleaning is an approach to redress the problems associated with traditional cleaning agents.
Alkylphenol ethoxylates and alkylphenols
Alkylphenol ethoxylates are widely used nonionic detergents for domestic and industrial use. They are susceptible to microbial or photochemical degradation into alkylphenols: lipophilic, hormone mimicking compounds. Endocrine disruption of alkylphenols was evidenced by research affirming cell proliferation in cells treated with alkylphenols, a response usually generated by oestradiol binding. Further investigation revealed that hormone mimicking alkylphenols affiliate with the oestradiol receptor and averts the proper binding and function of oestradiol. Male trout in alkylphenol contaminated rivers showed reduced testicular growth and synthesized 570,000 times more vitellogenin than did control male trout. The astonishing quantity of vitellogenin, a precursor of lipo- and phosphoproteins that make up egg-yolk protein, in the male trout population from River Lea of England exceeded that of females just before ovulation.
Since the discovery of its adverse effects on an organism’s endocrine system, the United Kingdom phased out the use of APEs as cleaning agents since 2000. To date, there are no regulations regarding the use or removal of APEs.
Environmentally benign alternatives
Green cleaning involves the use of products that biodegrade into innocuous compounds. Many of these products include natural solvents such as citrus, seed and vegetable oils that can be safely recycled back into the environment.
Naturally occurring substances that may replace synthetic cleaning products include vinegar, lemon juice and baking soda. Lemon juice may be used as a degreaser in the place of cleaners that contain chemically active solvents such as 2-butoxyethanol. Vinegar is another popular replacement for acidic cleaners that kill most bacteria and germs because the acetic acid it contains can upset pH balance. Baking soda, sodium bicarbonate, is an alkaline, buffering compound.
Other alternatives have been produced that aim at decreasing other waste involved with cleaning. For example, some brands of laundry detergent are now being formulated for use with cold water. By allowing the consumer to use cold water rather than hot, each load cuts back significantly on energy costs.
2-Butoxylethanol, ethylene glycol monobutyl ether (EGBE)
2-Butoxyethanol is a common glycol ether used as a solvent in carpet, hard-surface, glass, and oven cleaners owing to its surfactant properties. It is a relatively cheap, volatile solvent of low toxicity. It has the further advantage of not bioaccumulating.
