Emulsion cosmetics clean workshop
Emulsion cosmetics are daily cosmetics with good room temperature fluidity formed by emulsification technology of oil phase, water phase and emulsifier at a certain temperature. Good, low viscosity, usually by means of gravity or external force extrusion can produce flow; emulsion cosmetics have less oil content, generally less than 20%, good use feeling, more comfortable and smooth, no greasy feeling, easy to spread, good ductility , has a certain moisturizing, emollient effect, more suitable for use in summer or early autumn and other seasons. The preparation methods of emulsions mainly include natural emulsification and dispersion method, instant soaping method, phase inversion emulsification method, interface composite film production method, low-energy emulsification method, etc. Usually, natural emulsification method and interface composite film generation method are often used in laboratories to prepare emulsions.
The emulsification principle of moisturizing emulsion is similar to the emulsification principle of other types of emulsions. Both use emulsifiers to reduce the interfacial tension between the oil phase and the water phase, and form an emulsifier surrounding layer at the oil-water interface. The water groups are directed towards the water phase and the lipophilic groups are directed towards the oil layer, thus forming O/W or W/O emulsions. For quality inspection of refreshing moisturizing lotion, take samples for visual observation at room temperature and under non-direct sunlight. The moisturizing lotion should be milky white, delicate and lustrous; take samples for identification by smell, which is in line with the product set fragrance; use ordinary microscope to observe the shape of emulsified particles The appearance and size distribution are uniform; at room temperature, take a certain amount of product and put it in a small test tube, and let it stand for a period of time, observe the stability of the emulsion and record the observation phenomenon; Centrifuge at 2000r/min for 30min to observe the stability and record the phenomenon; take out 1 part, put it in -15～-5℃ for 24h, take it out, return to room temperature, observe its stability, if there is no oil-water separation and no discoloration, then the cold resistance test Success; take out 1 part, put it in a 40°C environment for 24 hours, take it out, return to room temperature, and observe its stability, if there is no oil-water separation, no discoloration, the heat resistance test is successful; take out 1 part, place it at room temperature, and place a month, observe whether there is fungus formation; take out 1 part, place it at 40°C for 24H and 0°C for 24H alternately for 3 months, observe its stability, if there is no oil-water separation, no color change, the high-low temperature cycle test is regarded as success. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for emulsion cosmetics clean workshops and purification workshops.
Preparation of nanoemulsion containing vitamin E and vitamin C in cosmetic clean workshop, weigh each component vitamin E, vitamin C, surfactant, IPM, deionized water for use; dissolve xanthan gum in distilled water, then add Vitamin C solution, stir to dissolve; dissolve microorganism E in IPM, stir, then add surfactant, stir evenly; slowly add oil phase to the aqueous solution, turn on the stirrer, add oil phase and stir until surfactant Completely dissolved, the solution becomes a colorless, transparent and clear liquid; after standing overnight, there is no delamination phenomenon, and it can be bottled after passing the inspection.
