The invention relates to a process for washing common textiles at room temperature moved in a rotary drum of a wringer washer, comprising at least one phase of washing the textiles to be washed, during which the textiles to be washed are in contact with an aqueous washing composition comprising: - an enzymatic detergent laundry agent comprising at least one nonionic detergent, at least one anionic detergent and at least one enzyme, and; - at least one alkaline laundry agent; characterized in that: the enzymatic detergent laundry agent has, in the aqueous washing composition, a proportion of between 2 and 5 grams of enzymatic detergent laundry agent per kilogram of textiles to be washed, in that the alkaline laundry agent has, in the aqueous washing composition, a weight proportion of between 3 and 7 grams of alkaline laundry agent per kilogram of textiles to be washed, the aqueous washing composition comprises a degreasing laundry agent comprising at least one nonionic surfactant, the degreasing laundry agent being used with a weight ratio, in the aqueous washing composition, of between about 1.0 gram and about 5.0 grams of degreasing laundry agent per kilogram of dry soiled textile(s), and in that the washing process is carried out at room temperature. The invention relates to a process for washing common textiles that can be marginally improved by adding ozone gas.

This invention relates to solid particles of a linear alkylbenzene sulfonate anionic detergent surfactant. These particles contain a polycationic salt of linear alkylbenzene sulfonic acid having both magnesium and sodium cations. The weight ratio of the magnesium salt of linear alkylbenzene sulfonic acid to the sodium salt of linear alkylbenzene sulfonic acid is in the range of 0.6:1 to 9:1.

The invention relates to a method for washing textiles moved in a rotating drum of a washer-extractor, comprising at least one phase of washing the textiles to be washed during which the textiles to be washed are in contact with an aqueous washing composition comprising: - an enzymatic detergent detergent comprising at least one non-ionic detergent, at least one anionic detergent and at least one enzyme, and; - at least one alkaline detergent; characterized in that: the enzymatic detergent detergent has, in the aqueous washing composition, a proportion of between 2 and 4 grams of enzymatic detergent detergent per kilogram of textiles to be washed, in that the alkaline detergent has, in the aqueous washing composition, a mass proportion of between 3 and 4 grams of alkaline detergent per kilogram of textiles to be washed, and in that the washing method is carried out at room temperature and without the intentional addition of ozone.Figure for abstract: Figure 1.

The present disclosure provides a method for extracting and purifying small rubber particle protein from Hevea brasiliensis latex, which comprises: adding an alkaline buffer solution to the latex to stabilize the latex; precipitating and removing most of the proteins and all latex solid components in the latex by a strong anionic detergent and an organic solvent, but the small rubber particle protein remains in a dissolved state; centrifuging the mixture to clarify the liquid portion, and transferring the clarified liquid portion; adding ammonium sulfate to the liquid portion and oscillating to precipitate the proteins, thereby obtaining a crude protein extract (mainly containing small rubber particle protein); separating the crude protein extract by ion exchange chromatography, collecting the main elution peak; further separating the proteins contained in the main elution peak of ion exchange chromatography by gel filtration chromatography, thereby obtaining purified small rubber particle protein. The method of the present disclosure can efficiently separate target proteins from non-target proteins in a time-saving manner.

The invention relates to a method for producing a decellularized tissue scaffold. The invention also relates to a tissue scaffold produced by the method. The invention particularly relates to a pig tissue scaffold. The methods include reduced levels of anionic detergents and avoid the use of protease inhibitors of animal origin to produce tissue scaffolds with advantageous properties.

The invention discloses a method for detecting the content of an anionic detergent in a rice and flour product based on an ultraviolet spectrophotometer, which comprises the following steps: adding water into the rice and flour product to be detected for soaking, and crushing to obtain rice and flour paste; mixing the rice and flour paste with water, and adding a potassium ferrocyanide solution and a zinc acetate solution for reaction to obtain an extracting solution of the rice and flour product to be detected; transferring part of the extracting solution of the to-be-detected rice and flour product to be mixed with a color developing auxiliary agent, adding an organic solvent to extract a compound formed by the color developing auxiliary agent and an anionic detergent in the extracting solution of the to-be-detected rice and flour product, and performing liquid separation to obtain an organic phase; testing the absorbance of the organic phase by using an ultraviolet spectrophotometer to obtain the absorbance of the organic phase; preparing sodium dodecyl benzene sulfonate standard solutions with different concentrations, and drawing a standard curve; and calculating the content of the anionic detergent in the to-be-detected rice and flour product based on the standard curve. The method is high in accuracy, low in detection limit concentration and low in cost.

A system, composition, method and kit for removing a detergent, such as an anionic detergent, from an aqueous solution, comprising a salt, a water immiscible alcohol of Formula I:R1—OH  (Formula I)where R1 is an optionally substituted, linear, branched or cyclic C4-C12 alkyl; anda water immiscible halocarbon, wherein said halocarbon is miscible with said alcohol of Formula I. The system can be used on aqueous solutions that contain detergents (such as Sodium Dodecyl Sulphate (SDS), for example), and any detergent-associated or detergent-bound molecules that may be present in the aqueous solution, to form an aqueous phase and a non-aqueous phase, for effectively removing the detergent and any detergent-associated or detergent-bound molecules, and sequestering them into the non-aqueous phase.

The present disclosure provides a unit dose product comprising a pouch formed from a water-soluble film material; and a detergent composition disposed within the pouch that comprises about 5 to about 20 wt % water, about 35 to about 65 wt % of at least one surfactant comprising methyl ester ethoxylate and no linear alkylbenzene sulfonate, and a non-aqueous solvent. The detergent composition comprises a Zein score of not greater than 2% dissolved zein when tested on a 3% dilution. The composition can further comprise additional components, such as a base, a performance polymer, an anti-redeposition agent, an enzyme, a bleaching agent, a bleach activator, a chelating agent, an optical brightener, a bitterant, a corrosion inhibitor, or a combination thereof. The detergent composition comprises surfactants with improved mildness and solvents with reduced allergic components.

A method for determining a level of one or more live microbes in a sample of a Cannabis plant includes (a) introducing a DNase enzyme into a sample including (i) Cannabis plant matrix derived from lysed cells of a Cannabis plant and (ii) live microbial cells including microbial genomic DNA, (b) introducing an anionic detergent into the sample, where the anionic detergent is in an amount effective to inactivate the DNase enzyme in the sample and lyse the live microbial cells in the sample, (c) introducing a known quantity of control DNA into the sample, (d) contacting the sample with a plurality of polynucleotide capture agents, (e) isolating the plurality of polynucleotide capture agents, thereby isolating polynucleotides from the microbial genomic DNA and / or control DNA in the sample, and (f) amplifying at least a portion of polynucleotides from the microbial genomic DNA isolated in step (e).
