The editorial board of the newspaper Mir Pensioner and ANO Rossiyskaya sistema kachestva (Roskachestvo) conducted a study that will help older people find answers to the main questions: which of the 31 types of washing powder is the best for washing things, and is it safe?
HARMFUL FROM HOUSEHOLD CHEMICALS
How harmful are washing powders? It depends on what is included in them.
• Surfactants (surfactants) – often it is the basis of washing powders and other detergents. These substances break down dirt on fabrics and pull them out by dissolving in water.
• Phosphates – substances that reduce the hardness of the water (in hard water, things are washed worse) and enhance the washing ability of the powder. They protect the washing machine from limescale, and the clothes from graying.
• Zeolites help to remove stains and bind salts of hardness of water. These substances do not dissolve in water, therefore, if there are a lot of them in the powder, the fabric becomes coarser.
• Enzymes are dietary supplements that speed up the washing process and help remove protein, starch, fat and other contaminants. The most common enzymes help break down proteins, so they are best at dealing with protein contamination (such as blood). However, mechanical destruction of the fabric also occurs because of them: do not use powder with enzymes for washing woolen and silk fabrics. They are of a protein nature – therefore, they will be destroyed by enzymes.
• Substances based on cellulose – thanks to them, the dirt does not “stick” back to the fabric.
• Color stabilizers do not allow things to fade, and also retain the dye so that the rest of the linen does not stain during washing.
• Optical brighteners are fluorescent substances. By settling on the fibers, they create the illusion of a whiter color and special purity of the thing.
There are many “horror stories” around the substances that make up the powder (especially surfactants and phosphates). Many new, environmentally friendly formulas of washing powders have been created without these substances. Eco-friendly laundry detergents were included in the study (Garden eco and Molecola), but they were worse than conventional detergents. The main question: is the listed “chemistry” really as dangerous as they say?
According to the research results, all powders do not irritate the skin, including do not corrode the skin of the hands, do not irritate the mucous membranes of the eyes, and do not cause allergies. They do not cause intoxication when the smallest particles of the powder are inhaled or when they enter the stomach, and do not disrupt the metabolism when they enter the bloodstream through the skin. Of course, all this does not mean that detergent powder can be eaten, inhaled and washed with it. However, if you follow the instructions for use indicated on the package, the powder will not bring any harm to the human body.
ERASE ONE TIME – SEVEN CLEARS
A standard machine wash includes three rinses. Some experts advise not to dwell on this and add two more cycles to them. Well, when washing by hand, rinse the laundry at least ten times.
What for? Chemical components of detergent powder may not be 100% washed out of fabrics. And although, as we have already said, they will not cause allergies and irritations in contact with the skin, the experts decided to “play it safe”. They estimated how much surfactant remains in the water (and therefore on clothes) after three rinses. However, the amounts of surfactants that are not washed out of fabrics after washing do not exceed the permissible limits. This means that it is not dangerous for humans.
SPOT ON REPUTATION
Washing powder for colored laundry is intended for washing away dirt and preserving the color of the laundry. Stain removers are needed to remove tougher stains.
Experts assessed how well the powders wash away protein dirt (blood) and pigment-oil (oil, grease, sweat). It turned out that washing powders, on average, remove pigment-oil stains worse than protein ones. Twice as many powders coped with protein contamination than with fatty ones. The worst result for washing protein stains is 56%, and for washing fatty ones – 28%. The latter means that the stain was removed at best by a quarter.
Fat, as you already understood, is more difficult to remove than blood and milk.
• Perfectly dealt with fat (oil pollution):
Stork, Biolan, Kapel, Ordinary Powder, BioMio, Burti, Ecover, Free time, Frosch, Reflect, Dosia, Ariel and Sarma.
• Worst of all rubbing off fat Econel and my love (only 28%), Luch automat and Garden eco (34% pollution), as well as “Purity Recipes “ (washed away fat by 37%).
• They perfectly removed the blood, that is, protein contamination:
Stork, Biolan, Myth, Ordinary Powder, Pemos, Recipes for Purity, Seagull, Amway, Ariel, BiMax, BioMio, Burti, Cj Lion Beat Drum, Deni, Dosia, Ecover , Free time, Frosch, Losk color, Meine Liebe, Persil, Reflect, Sarma, Sorti and Tide.
Although the powders are not designed to clean stains, experts have tested how detergents work on red wine, ink and rust. It turns out that a stain remover is not always needed.
• Red wine is perfectly washed My love and Sarma…
• Ink was best handled My love and Sarma, BioMio and Cj Lion Beat Drum, Amway and Burti…
• Rust is better than others Persil and Burti…
POWDER AND FABRIC
The study gave interesting facts about the effect of the powder on the fabric of the washed item.
Strength. After 25 washes at a water temperature of 40 ° C, in some cases the clothes turned gray, in some they turned yellow, or both. The fabrics also lost strength in width and length, or both. According to experts, on average, powders after 25 washings reduce the strength of the washed items by 23-27%.
Loss of color. Tests on the effect of powder on color loss were carried out on blue samples, since red and blue dyes are considered the most unstable. Bottom line: after 15 washes, all things lost their color – from three to fifteen percent.
Relationship. But there were practically no pellets on the washed things even after 15 washes at 40 ° C. That is, none of the detergent powder contributes to the formation of pellets. You can safely wash even knitwear, because knitwear is more prone to pilling than other materials.
The stiffness and roughness of the fabric. If too much minerals from the powder are deposited on the fabric during washing, the fabric may become stiff and coarse after several washes. How many such “precipitation” is – this is evidenced by the ash content indicator. According to the norms established by Roskachestvo, it should not be higher than 1%. Ash content in Dosia and Ariel turned out to be slightly higher than the leading requirements – 1.1%. Have “Myth” – 1.6%, in BiMax – 2.7%.
POWDERS THAT FORM TOO MUCH FOAM:
• Zifa – 220 mm;
• “Recipes for Purity” – 202 mm;
• Wire – 202 mm;
• Reflect – 200 mm;
• Free time – 195 mm;
• “Regular Powder” – 187 mm;
• Came out – 187 mm;
• Econel – 181 mm.
