Generally, commercially available detergents and cosmetics often contain harmful substances, which are not only harmful to the body but also affect the environment. Therefore, the Environmental Protection Agency restricts the use of these harmful substances in the environmentally friendly cleaning products. Please check whether the ingredients of the home cleaning products contain harmful substances. , The ingredients of general cleaning products are marked in English, you do not need to check it, if there are the following harmful substances, please replace and use safe cleaning products.
A. Substances restricted by environmental label cleaning products:
1. Surfactant (Surfactant) biodegradability:
The percentage of cleaning agent solution that is decomposed and digested by microorganisms. The higher the degree of decomposition, the easier the cleaning agent is to be biodegraded, and the less cleaning agent remains in the water. The environmental protection label specification standard requires that the biodegradability of cleaning products is more than 90%, and the biodegradability of dishwashing liquid is more than 95%, and it must contain more than 50% of natural raw materials. Natural raw materials refer to those extracted from animals and plants. Surfactants made of raw materials (such as fatty acid sodium, fatty acid potassium), so the indicated biodegradability also represents the safety of the surfactant.
2. Phosphoric acid:
The most commonly added as a hard water softener in detergents is sodium tripolyphosphate (STPP) (Sodium Tripoly Phosphate). The phosphorus contained in it is discharged into the receiving water body, causing eutrophication of lakes and rivers. Algae and plankton in the water multiply, resulting in the increase of foul smell and suspended solids, and the deterioration of water quality such as hypoxia. Domestic wastewater treatment is not popular in countries, and environmental protection label specifications and standards tend to be banned or restricted.
3. Fluorescent agent:
It is one of the additives in detergents. In fact, it is a dye, which can absorb ultraviolet rays from sunlight, causing the illusion of whiter clothes. It has no washing function. However, due to the controversy of causing cancer and skin lesions, international environmental labels promote National standards for cleaning agents ban or limit the use of fluorescent agents.
That is, Nitrilo Triacetic Acid is added to the detergent to replace STPP (Sodium Tripoly Phosphate) as an enhancer (Builder), which can be combined with Ca and Mg in water to precipitate and have a water softening effect. However, NTA is a micro-carcinogen. Due to its chelate property (Chelate), it can cause heavy metals to be re-dissolved in the sediments of rivers and lakes and increase the concentration of heavy metals.
The removal rate of wastewater treatment plants has an adverse effect. The environmental protection labels of Germany, Singapore, Sweden and other countries are all banned.
Ethylene Diamine Tetraacetic Acid is also an enhancer in detergents. Its function and impact on water quality are similar to NTA. The environmental protection label promotes countries, and most of them list EDTA as a prohibited additive in detergents.
Alkyphenol Ethoxylate is toxic and difficult to decompose. It is banned in Germany, Singapore, New Zealand, and Canada.
Perborate, which is generally used as a bleaching agent or preservative, produces hydrogen peroxide in an aqueous solution. Due to toxicity, environmental labels in Germany, Singapore, Sweden and other countries are prohibited or restricted.
8、 Chlorine Bleach ：
Chlorine-containing bleach is toxic. When chlorine reacts with water or water vapor, it will become highly toxic and corrosive hydrogen chloride vapor. When chlorine comes in contact with many common chemicals, it will explode or form explosives. Therefore, the environmental labels of various countries are clean. All agents are banned.
9、 Formalin ：
Namely, formaldehyde (formalin) is a transparent solution with a strong irritating odor. It can be used as an antiseptic and disinfectant. The environmental labels of various countries are prohibited.
10、 Formaldehyde ：
Namely formaldehyde HCHO, it is a colorless, irritating and toxic gas, easily soluble in water and methanol, and has disinfecting and antiseptic effects.
11、 Opacifier ：
It is milky whitening agent, an additive commonly used in European and American countries to make transparent liquid opaque and increase its consistency. It has nothing to do with detergency and is not easy to decompose, so it is forbidden.
