Cosmetic equipment steps for the production of emulsion cosmetics

Release time:


Cosmetic equipment is the mainstream equipment of modern cosmetics production, with the development and progress of emulsification machinery equipment, cosmetic equipment equipment has become more and more intelligent, its multi-functional integration of powerful performance, intelligent operation and adaptability with other equipment, so that cosmetic equipment equipment is more and more accepted by the cosmetics industry. The standard cosmetic equipment includes water, oil pan and main pan, which integrates the functions of pre-mixing and dissolution, vacuum suction, stirring, heating, homogenization and emulsification, defoaming and cooling, greatly reducing the process and convenient feeding, discharging and cleaning. Let's take a look at the production of cream cosmetics through complete sets of cosmetic equipment.

Preparation of oil phase

The emulsion material cosmetic oil phase raw materials: oil, fat, wax, emulsifier and other oil-soluble ingredients into the oil phase pot, openCosmetic EquipmentElectric heating or steam heating, stirring in the pot while heating70~75 ℃, let the oil phase mixture is fully dissolved and heated for use. It should be noted that it is necessary to avoid long-term heating or excessive heating, and the phenomenon of oxidation and deterioration of oil phase raw materials. Easily oxidized oil, preservatives and other materials in the oil phase pot dissolved evenly, you can carry out the emulsification process.

Preparation of aqueous phase

Deionized water is required for the preparation of the aqueous phase. Deionized water is added into the aqueous phase pot, and water-soluble components such as glycerin, propylene glycol, sorbitol and other humectants, alkalis, water-soluble emulsifiers, etc. are added into it, heated to 90-100 ℃ while stirring, sterilized for 20min, and then cooled to 70-80 ℃ for use. If the cosmetic formulation contains a water-soluble polymer, it is recommended to prepare it separately, dissolve it in water, and stir it at room temperature to make it swell evenly to prevent clumping. If necessary, it can be homogenized and added to the aqueous phase before emulsification. To avoid prolonged heating, so as not to cause viscosity changes. In order to supplement the moisture volatilized during heating and emulsification, 3% ~ 5% more water can be added according to the formula. The exact quantity can be obtained by analyzing the moisture of the finished product after the first batch is made.


The above oil phase and water phase raw materials are added into the stainless steel emulsifying pot in a certain order through a filter, and stirred and emulsified for a certain period of time at a certain temperature (e. g., 70-80 ° C.). Throughout the emulsification process, the method of adding the oil phase and the water phase (oil phase to the water phase or water phase to the oil phase), the rate of addition, and.Cosmetic EquipmentThe mixing conditions, emulsification temperature and time, the structure and type of emulsifier have a great influence on the shape and distribution of the emulsion particles. The speed and time of homogenization vary with different emulsifying systems. The speed and time of homogenization of the system containing water-soluble polymers should be strictly controlled to avoid excessive shear, damage to the structure of the polymer, causing irreversible changes, and changing the rheological properties of the system. If the formula contains vitamins or heat-sensitive additives, it is added at a lower temperature after emulsification to ensure its activity, but attention should be paid to its solubility.


AfterCosmetic EquipmentAfter emulsification, the emulsifying system is cooled to near room temperature. The unloading temperature depends on the softening temperature of the emulsifying system, and it is generally advisable to use its own gravity to flow out of the emulsifying pot. Of course, it can also be pumped out or pressed out with pressurized air. The cooling method is generally to pass the cooling water into the jacket of the emulsifying pot, stirring and cooling. The cooling rate, the shear stress during cooling, and the end temperature have an impact on the particle size and distribution of the emulsifier system, and the optimal conditions must be selected according to different emulsifying systems. Especially from the laboratory test to large-scale industrial production is particularly important.

Aging and filling

Generally, it is stored and aged for a day or a few days before filling with a filling machine. The quality of the product shall be assessed before filling, and the filling can only be carried out after the quality is qualified.

As the technology of cosmetics research and development becomes more and more mature, there are many kinds of empirical methods for preparing emulsions. Manufacturers can choose the preparation method according to the needs of products and personal experience, but no matter which method is selected, it must first meet the basic requirements of cosmetics production. Mature process and formula, select the appropriate emulsification equipment, the use of reasonable preparation methods, in order to get the high quality products.
