By treating oils at ordinary or reduced temperature with a mixture of sodium chromium salt and sulfuric acid, oxidation products are obtained suitable for the preparation of solid soap.

For example: 100 parts by weight of linseed oil are mixed with a solution of 3 parts by weight of sodium chromium salt and 3 parts by weight of concentrated sulfuric acid in 20 parts by weight of water. The oil is thoroughly mixed with an oxidizing solution and left to stand at ordinary temperature for 12 hours with slight stirring. Then the mixture is left alone, after which the oil is separated from the aqueous solution, washed with water and serves as a material for soap making.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food.

Poisons in baby strollers 17.09.2006

Commissioned by the German Consumer Protection Society, chemists tested 15 folding baby strollers from various manufacturers for hazardous compounds. They checked the handles of the stroller, the seat, fabric elements, protective canopies from the rain.

Nothing suspicious was found in five carriages. In two, polycyclic hydrocarbons were found - compounds that can accumulate in the body, cause skin cancer and damage chromosomes. In one model, organic tin compounds were found that have a negative effect on the hormonal system. In nine - phthalates, used as plasticizers in plastic parts and harmful to the sex glands.

Six members of this group of chemicals are prohibited from being used in children's toys. True, in no case have such concentrations of harmful substances been found that would cause acute poisoning in a child or an adult carrying him.

But no one can say how low concentrations of these substances act in combination and with prolonged contact with the skin of a child.
