The invention relates to the field of sizing agents in the papermaking industry, in particular to alkenyl succinic anhydride sizing agent emulsion, which comprises white mud waste residue, alkenyl succinic anhydride and water, wherein a mass ratio of the alkenyl succinic anhydride to the water is 1:(1-4), and a mass ratio of the white mud waste residue to the alkenyl succinic anhydride is 1:(20-1,000). The preparation method comprises the following steps of: dispersing the white mud waste residue into the alkenyl succinic anhydride, adding the water, and mixing uniformly; or dispersing the white mud waste residue into the water, and uniformly mixing with the alkenyl succinic anhydride to prepare the stable oil-in-water (O / W) alkenyl succinic anhydride (ASA) emulsion. The industrial waste residue is recycled, and virtuous economic cycle is realized; the white mud serving as an emulsifier is lower in consumption compared with an inorganic nano-material serving as an emulsifier; under the condition of low consumption of the emulsifier, a good sizing effect can be achieved, so that the emulsification cost is lower; the alkenyl succinic anhydride sizing agent emulsion has the advantages of simple emulsification process and high concentration of the prepared emulsion; and after the alkenyl succinic anhydride sizing agent emulsion is diluted with water and added into a paper stock for sizing in pulp, and the sizing efficiency is high.

The invention discloses a paeonia ostii seed natural activity skin cream which comprises the following component substances: paeonia ostii seed oil, paeonia ostii seed general flavone extract, an emulsifier and a solvent, wherein the melting point of the emulsifier is 30-65 DEG C, and the emulsifier is solid at normal temperature; the solvent is a mixture of glycerol and propylene glycol. The invention also discloses a method for preparing the paeonia ostii seed natural activity skin cream. The method comprises the following steps of: fully mixing the emulsifier and the paeonia ostii seed oil at the temperature of 65+ / -5 DEG C, reducing the temperature, adding the solvent and the paeonia ostii seed general flavone extract, mixing and continuously reducing the temperature to be 0+ / -10 DEG C, performing microwave emulsification on the mixture, and obtaining the product. The paeonia ostii seed natural activity skin cream has the sunscreen, skin care, skin whitening, health care and inflammation diminishing effects; the method for preparing the paeonia ostii seed natural activity skin cream is simple, low in emulsification cost and easy for industrial production.

The invention relates to the field of sizing agents in the papermaking industry, in particular to an alkenyl succinic anhydride sizing agent emulsion, which contains white mud waste residue, alkenyl succinic anhydride and water, and the mass ratio of alkenyl succinic anhydride to water is 1:1~4 ; The mass ratio of white mud waste residue to alkenyl succinic anhydride is 1:20~1000. The preparation method is to disperse the white mud waste residue into alkenyl succinic anhydride, and then add water to mix evenly; or disperse white mud waste residue into water, and then mix evenly with alkenyl succinic anhydride to prepare a stable O / W type ASA emulsion . Realize the recycling of industrial waste residues, and realize a virtuous economic cycle; the amount of emulsifier used when white mud is used as an emulsifier is lower than that of inorganic nanomaterials, and it can achieve good results at a lower amount of emulsifier. sizing effect, so the cost of emulsification is lower, and it also has the advantages of simple emulsification process and high concentration of the prepared emulsion. After diluting and emulsifying with water, it is added to the paper material for in-pulp sizing, and the sizing efficiency is high.
