The invention discloses a silicone oil composition for hair care, the silicone oil composition for hair care comprises an emulsifier and a block copolymer, and the block copolymer is composed of A-b-B-b-A, wherein A is a polysiloxane chain segment, B is a polyurethane chain segment, and b represents a block; the polyurethane chain segment is chemically bonded with a polyethylene glycol chain segment and / or a tertiary amine structure. The silicone oil composition for hair care is easy to emulsify and good in adsorption and film-forming performance, the formed emulsion is good in stability, the silicone oil composition for hair care can be applied to hair care products, and the hair care products prepared from the silicone oil composition are good in smoothness and extremely excellent in hair care effect.

This invention relates to the field of needle-free injector technology, and in particular to an apparatus and method for needle-free injection of local anesthetics into the dermis for infiltration anesthesia. The apparatus includes a receiving space for containing the anesthetic solution; the injection pressure is 14-21 MPa. This invention allows for the design of different needle-free injectors to address the physiological differences in the dermis between men and women, ensuring precise intradermal injection of the anesthetic solution and avoiding entry into the muscle layer. Furthermore, it results in less pain during injection and a longer duration of effect from the onset and exhaustion of the local anesthetic.

The invention provides functional rare earth-containing growth factor gel and a preparation method thereof, the gel is prepared from a matrix, NGF and rare earth-manganese bimetallic nano-enzyme CeMn NP-PEG according to a mass ratio of 10: 1: (0.2-1), the CeMn NP-PEG is CeMn NP with the surface modified with PEG, the CeMn NP is prepared from Ce (Ac) 3. NH2O and Mn (Ac) 3. 4H2O through a sol-gel reaction, and the doping amount of Ce is 20 wt%-50 wt%. According to the gel, CeMn NP-PEG, NGF and a matrix are integrated into an integrated functional dressing, the antioxidant function is achieved through the ROS removal effect, a foundation is laid for follow-up achievement of inflammation regulation and control, nerve-blood vessel-epidermis synergistic repairing and healing promoting effects, and the gel is expected to meet the clinical requirements for rapid and high-quality healing of common wounds.
