Definition of soap powder

soap powdernoun

bột xà phòng

/ˈsəʊp paʊdə(r)//ˈsəʊp paʊdər/

The term "soap powder" was used in the past to describe a product that was a precursor to the modern-day laundry detergent. In its earliest forms, this product was made by forming a paste of strong alkali, soap, and water, which was then dried and ground into a powder. This powder, also known as "washing soda," was added to water to create a soapy solution for washing clothes by hand. The use of soap powder as a laundry detergent gained popularity during the 1900s as boiler washing machines became more common. These machines allowed for larger quantities of laundry to be washed at once, making it necessary to have a more concentrated cleaning agent than the traditional soapy solution made with bar soap. The powder formula was also advantageous as it could be easily dissolved in water, making it ideal for use in washing machines. As a result, soap powder became a staple in laundry rooms around the world, and many popular brands such as Tide, Cheer, and Persil continue to offer powdered versions of their laundry detergents today. However, in recent years, the use of soap powder has declined somewhat, as liquid liquid detergents have become more popular due to their convenience and efficiency. Nonetheless, soap powder remains a preferred option for those who prefer the traditional hand-washing method or for use in automated washers without high-efficiency detergent dispensers. In summary, the origin of the word "soap powder" can be traced back to the early 1900s when it was used as a concentrated cleaning agent for washing machines. Its popularity persists to this day, although the use of liquid detergents has become more common in recent years.
