A scale inhibitor squeeze treatment is enhanced by injecting a pre-flush solution into a wellbore, where the pre-flush solution includes at least one organic carbonate solvent, such as a dialkyl carbonate and/or a cyclic carbonate. The use of an organic carbonate solvent can help prevent the pre-flush solution emulsion formation, help avoid water-blocking, and enhance scale inhibitor adsorption. The use of an organic carbonate solvent also permits the pre-flush solution to be free of water, in one non-limiting embodiment.

Provided is a spreading agent that has a high water solubility and can effectively enhance the adhesion force of a fertilizer component or an agricultural chemical to a plant. This spreading agent contains at least one oligosaccharide selected from the group consisting of a chitin oligosaccharide, a cello-oligosaccharide and a xylo-oligosaccharide.

The present invention relates to an amphipathic compound, a preparation method therefor, and a surfactant composition comprising same and, specifically, to a compound selected from the group consisting of steviol monoglycoside-acid, steviol monoglycoside-ester, and steviol monoglycoside-amide, a preparation method therefor, and a surfactant composition comprising at least one of these compounds.

The invention described herein provides methods and materials that can impart long-term stability to polyelectrolyte complex coacervate droplets and create complex coacervate emulsions. The methodology described herein is designed to use one or more of a wide variety of comb polyelectrolytes in order to produce stable water-in-water emulsions with precisely controlled droplet size and enhanced stability profiles. The stabilized water-in-water emulsions microdroplets of the invention can further encapsulate active agents such as proteins and the like in a manner that protects them from the surrounding environment, thus allowing the compositions to serve as bio-microreactors and the like.

Disclosed are natural surfactant compositions comprising saponins derived from non-woody plants of the genus Hesperaloe. The saponins are useful in the formulation of natural surfactant compositions and may be combined with other natural surfactants, such as alkyl polyglucosides active. The surfactant compositions may be used in agricultural composition, particularly aqueous foliar sprays, to improve the wetting properties of one or more active agents.

The disclosure discloses a Pickering emulsion stabilized by cellulose from ginkgo seed shells and a preparation method thereof, and belongs to the fields of preparation methods of biomass materials and food chemical industry. The disclosure uses ginkgo seed shells as a raw material to obtain high-purity cellulose through hot alkali treatment and sodium chlorite bleaching. After the cellulose is dried, the cellulose is hydrolyzed with sulfuric acid to obtain a cellulose nanocrystal suspension. The suspension is mixed with an oil phase, and the Pickering emulsion is obtained through high-speed shearing and homogeneous emulsification. The disclosure can prepare cellulose nanocrystals with different aspect ratios by adjusting the parameters of high-speed shearing and homogeneous emulsification according to actual production needs. Cellulose nanocrystals with high aspect ratio can be used to prepare stable Pickering emulsions with high oil phase and high viscosity, which can be applied to the fields of food, cosmetics and the like; and cellulose nanocrystals with low aspect ratio can be used to prepare Pickering emulsions with low viscosity and high fluidity, which can to be applied to the fields of food and medicine.
