4 results about "Synthetic Detergents" patented technology

According to a natural detergent composition, a detergent composition according to one aspect does not use synthetic chemical components such as metal ion chelating agents, unlike conventional synthetic detergents, so it does not cause environmental pollution, is harmless to the human body, is non-irritating to the skin, has low mineral salt precipitation, and has excellent cleaning power.

A sampling device for anionic synthetic detergents used in tableware relates to the field of tableware sample liquid sampling technology. Its main structure includes: a sample liquid collection box placed inside a base, with tableware placed within the box; rinsing nozzles connected to the outlet of a peristaltic pump via pipes; a local unit receiving point cloud data from a 3D vision camera and a laser contour scanner, processing it, completing 3D modeling, calculating the inner surface area of ​​the tableware, calculating the required running time of the peristaltic pump and sending the calculations to a PLC controller, and generating a rinsing path plan; the PLC controller controlling the peristaltic pump to start and stop according to the running time, and controlling the first robotic arm to move according to the rinsing path plan, driving the rinsing nozzles to complete the rinsing of the tableware. This invention solves the problems existing in the measurement of the inner surface area of ​​tableware and sample liquid preparation in the prior art, improving the accuracy and efficiency of sample liquid preparation for the detection of anionic synthetic detergents in tableware.

The present invention relates to a solid laundry composition. It particularly relates to a solid laundry composition having a desirable foam profile during the laundering process. There remains a need for a solid laundry composition which is an environmentally friendly composition and includes lowered levels of synthetic detergents while providing desired foaming profile. It is an object of the present invention to provide a solid laundry composition which provides good foam profile and good cleaning performance. The present inventors have found that a solid laundry composition having 0 wt.% linear alkyl benzene sulphonate surfactant when present in combination with specific surfactant of general formula (Ia) or (Ib) and / or general formula (IIa) or (IIb) and alkali metal carbonate surprisingly provides good foam profile and good cleaning performance. The foam profile involves formation of good foam in the wash stage while eliminating the foam quickly during the rinsing stage. This benefit was preferably found across different consumer washing habits and fabric types present in the wash load.

The invention relates to the field of nonferrous metallurgy, and can be used for preparing commercial products from waste materials generated by wet purification of residual waste gas containing hydrogen fluoride and sulfur dioxide in an aluminum production electrolysis workshop. According to the invention, a sodium sulfate mixture with high whiteness coefficient and low yellowing index can be obtained from a circulating solution (including a solution subjected to defluorination treatment by extracting secondary cryolite) for gas purification of the waste aluminum electrolysis cell, namely a product which is suitable for producing synthetic detergents and has competitive price. The method comprises the following steps: firstly, clarifying a waste sodium sulfate solution by using a synthetic flocculant so as to reduce the content of suspended matters in villiaumite-containing and gas purification slurry; the filtration of the slurry of the sodium sulfate mixture is combined with washing with cold industrial water, and the dried sodium sulfate mixture residue is ground to a particle size of less than 200 microns to increase the whiteness coefficient.
