laundry detergent reviews

Every detergent soap-based or soapless contains many ingredients, and by altering the proportions of these and subjecting them to many processes, many different laundry detergent reviews products may be formulated, each having definite advantages for a particular cleaning job, soap.
The raw materials from which soap is manufactured are natural animal or vegetable fats, combined with certain chemicals, called alkalis. The fats used vary: there may be whale oil from Antarctica, coconut oil from Ceylon, palm oil from Nigeria, peanut oil from India, or tallow hom sheep and cattle-producing countries.

The raw materials used for many laundry detergent reviews that the manufacture of synthetic detergents are pure chemicals, derived initially from crude petroleum oil. Crude oil is an organic substance-which in simple terms means it is derived from once-living organisms. It is believed these creatures were sea animals, which died millions of years ago and were buried deeper and deeper into the ground, over the years.

laundry detergentThe masses thus formed have been subjected to extreme pressures and temperatures, and have over countless centuries been transformed into what we now know as crude oil. It is a strange thought -sea animals into modern detergents. this is a fascinating snippet of information to think about when adding detergent to washing machine. A variety of extra chemical substances are added to all washing products to assist the detergent power of the mixture. Some of these ‘builders’ or ‘adjuncts’ are inorganic, which means they have never been living organisms, and to put it extremely simply, they are chemicals dug up or mined from beneath the earth or sea. A typical soapless detergent powder has 60 per cent of these substances in its composition, and a typical soap powder about 30 per cent. Soap flakes usually have about 10 per cent added material. These builders or adjuncts may consist of some or all of the following, Alkaline additives These help to give effectiveness to the detergent, especially in dealing with oily dirt. The additives may be silicates or phosphates. A balance has to be struck between washing efficiency and the degree of harshness on the hands, and this is denoted by the term pH value.

If the pH value was too high, i.e. if too much alkalinity was produced, the cleaning power would be outstanding but the hands would suffer. If the pH value was too low, the cleaning power would be considerably reduced. A heavy duty powder may have a pH value of between 10 and 11.5. Liquid detergents have a pH of around 7.5, i.e. they are more or less neutral. Mild bleaching agents If detergents are to be able to clean heavily-soiled clothes, they must be able to remove stubborn stains. Stains are, in fact, substances which have become attached to the fabric by strong chemical bonds. If the stain is to be removed, the bonds attaching it to the fabric must be broken. In order to do this, chemical means must be used, and the usual method is to bleach the stain, i.e. destroy the bonds chemically. In detergents for use with the high-temperature wash, therefore, a substance called sodium perforate, which is a mild bleaching agent, may be included. This only becomes effective when the temperature of the water is just above 1800 F (80° C) – a temperature which would be far too hot for hand washing- and the greatest effectiveness is achieved when the water is at boiling. At these temperatures the sodium perforate bleaches the stain by oxidizing it. Of course, only mild bleaching agents are used in detergent powders; strong ones would weaken the fabric. But the chemical action is sufficient to decolorizing most of the ordinary food stains on, say, table linen.

Dirt suspension It is use to remove the dirt from clothes if it is re-deposited before the washing process is completed. In order to prevent this, chemicals that have dirt-suspending properties are added in small amounts to nearly all detergent powders. Optical whiteners One of the most interesting builders added to a detergent is the Fluorescent ‘optical whitener’ which, although colorless in itself, is able to absorb light in the ultra-violet region of the spectrum and re-emit visible fluorescent light. This means that the whiteness of a white article appears to be enhanced. We housewives have become so convinced that for our washing to be clean it must glow with whiteness and brightness that the obliging soap powder manufacturers have produced this effect for us. In fact, even if the article was not quite clean, it would still be possible for it to have this sparkling white appearance. Home economists are, however, expressing concern because over many weeks of washing these fluoresces can gradually build-up on the fabric until instead of a sparkling white article the fabric may take on a pinkish or bluish appearance. The answer to this problem may he in introducing new types of fluoresce which do not have this side-effect. Foam stabilizers certain laundry detergent reviews product, principally derived from coconut or palm kernel oil, have the ability to sustain sudsing during washing, thus allowing the volume of lather to act as a guide to the housewife that the washing solution still has cleaning power. Fillers A filler such as sodium sulphate may be added to synthetic detergents. It gives bulk to the powder and keeps down the cost. Those added extras Often chemicals are added to a powder to give extra sales appeal. These gimmicks may or may not have an effect on the washing ability. Often a detergent is given a pleasant colour, or smell. This perfume may even last when the clothes have been ironed. This may be pleasing for the housewife on articles such as towels, handkerchiefs and sheets, though it might be rather less pleasing to a husband who arrives at the office and finds that his shirts are distinctly sweet smelling.
