Pesticidal compositions containing as a pesticidally acceptable carrier, at least one plant essential oil compound as a pesticidally active ingredient; and isopropyl myristate, isopropyl palmitate or analogs thereof, as a synergist, and methods for using same, are disclosed.

The invention belongs to the fields of research and development of drugs and health-care products, particularly relates to an application of a nicotinamide mononucleotide containing composition to ageing resisting drugs / health-care products, provides a composition, further provides a preparation method of the composition, and further provides the composition or the application of the product prepared by the preparation method to ageing resisting drugs / health-care products. NMN can achieve the effects of activating organism energy metabolism and improving an organism oxidation stress reaction, and besides, through cooperation with synergism of other components, favorable effect of resisting ageing can be achieved; and the components in the composition are stable in structure. The prepared product is not liable to deteriorate or damage, and besides, the components are safe. The product basically has no poor reaction on human bodies. The composition solves the technical problems that in the prior art, the ageing resisting products do not have favorable ageing resisting effect, are free from damage to human bodies, and are stable in product quality.

The invention discloses a preparation method of a rare-earth magnesium nickel based hydrogen storage alloy. The preparation method comprises the following steps: adopting a round or square graphite electrolytic cell, putting a carrying crucible at the bottom of the electrolytic cell, and presetting a certain amount of addition element metal blocks into the carrying crucible; taking fluoride molten salts including REF3-LiF-MgF2-BaF2 and the like as an electrolytic medium and a mixture of RE2O3 and MgO as a raw material, electrochemically precipitating out RE and Mg together at a cathode to obtain an RE-Mg alloy which sinks into the carrying crucible and alloyed with the metal blocks preset in the crucible so as to obtain the rare-earth magnesium nickel based hydrogen storage alloy. The preparation method can be used for effectively solving the problem of volatilization and oxidation of magnesium during smelting of the rare-earth magnesium nickel based hydrogen storage alloy, and is safe in production process, short in flow and low in cost. The rare-earth magnesium nickel based hydrogen storage alloy prepared by the method can be directly crushed mechanically or subjected to hydrogen crushing to obtain rare-earth magnesium nickel based hydrogen storage alloy powder, or can be used as a master alloy which is subjected to pouring or rapid quenching after a certain raw material is added, and then is crushed mechanically or subjected to hydrogen crushing to obtain the rare-earth magnesium nickel based hydrogen storage alloy powder.

The invention relates to the technical field of medical appliance, in particular to a surface antibacterial treatment method and a device thereof for preparing a nano silver- and porous structure-containing medical high molecular material. The biggest problem of the implantation-type or insertion-type medical high molecular material in the clinical application is the infection which is caused by a biological film formed by the adherence of bacteria on the surface. A nano silver / polymer honeycomb structure-containing film can be processed and formed on the surface of the medical high molecular material through a water auxiliary method so as to realize the double antibacterial purposes of nano silver antibacterium and honeycomb structure antibacterial adsorption. The method has simple process, low requirement on equipment and strong universality, and is an economical, convenient and highly controlled antibacterial surface treatment method.

The invention provides repair cream suitable for skin with eczemas. The repair cream has the effects of deeply moistening the skin, reinforcing skin immune capacity, repairing damaged cutin, and preventing dependent dermatitis caused by hormone. The repair cream can effectively relieve the skin with eczemas; and compared with the commercially available cream, the repair cream has more excellent effects of moisturizing, preventing allergy and removing redness. The repair cream suitable for the skin with eczemas is prepared from the following components: 20-65% of a solvent, 6-34% of grease, 0.5-14% of an emulsifying agent, 12-36 parts of a humectant, 12-56% of a repair factor and 13-58% of anti-inflammatory and bacteriostatic components.

The invention discloses a whitening and moisture-retention gel containing suspension essential oil droplets used for sensitive skin and a preparation method and an application thereof. The gel is composed of a water-phase thickening agent, grease, essential oil, a humectant, a fat-soluble whitening agent, a water-soluble whitening agent, an antiseptic and deionized water, and optional essence, andthe suspension droplets are formed by grease, essential oil and the fat-soluble whitening agent. The whitening and moisture-retention gel has four effects of smoothing, moisture retention, nourishingand whitening; the whitening and moisture-retention gel has safe component and does not contain an emulsifier, greatly reduces the skin stimulation risk for population with sensitive skin while in use, and has the advantages of safety and low stimulation.
