Cosmetic creams and lotions are common daily skin-care products in life. they have variety of effects depends on what ingredients they made from, but the basic manufacturing process is the same.
Cosmetic production of creams and lotions is actually an emulsification process, products can be an oil-in-water (O/W) or water-in-oil (W/O) emulsion, or maybe a complex emulsion (Like: W/O/W). technically, a simple emulsion of oil and water, might be droplets of oil dispersed in water or droplets of water dispersed into oil. and that before, they were two immiscible liquids. a manufacturing process of liquid BB creams as follows for you referring:
Using traditional agitator might be encountered with these questions:
To solve these problems on cosmetic production of creams and lotions. KOSBEST specially promo a KOS series vacuum emulsifying mixer which designed with a structure of high-speed homogenizer and low-speed stirrer for getting a non-agglomerate and stable emulsion.
There are a number of machines for emulsion application, the suitability of which is dictated by individual processing requirements, including batch size, formulation and viscosity of the end product. the emulsification of some products may only require a simple homogenization system, but in the production of high-end products such as cosmetic creams and lotions, a single-function homogenizer cannot meet all production needs, which is why the multi-functional vacuum emulsifying mixer is so widely used in the cosmetic industry.
How it can helps:
When under work of an Vacuum Emulsifying Mixer, the materials continuously produces new interfaces by the PTFE scraper of stirring frame on the pot wall of emulsifying mixer, then through the frame agitator and counter-rotating stirring blade to be cut, compressed, folded, mixed and forming a downward vortex. the materials flow down the vortex to the homogenizer at the bottom, then it will be cut again and broken into a small droplet size 2-5μm by fast in the shearing gap when through between the high speed rotating rotor and static stator. then finally turns out a stable lotions and creams.
Sum: The emulsifying mixer by reduces the size of large droplets to increase the number of dropltes to achieve the effect of shearing and homogenuous. the greater the shearing force, the thicker and finer the product. On the other hand, the smaller the droplet size, the smaller the collision cotact area between the droplets, thereby making the emulsion and cream more stable within a certain range. BUT, a stable product no only base on that one thing, it also depend on your formula, emulsifying agent and temperature etc factors, and not mean the stonger the high shear force, the more stable the product. a rotation speed too high may cause the destruction of the emulsion system and loss of stability. for this reason, the speed of our emulsifying mixer is generally set at 0-3000rpm, which can ensure sufficient shear force without over-shearing the emulsion and affecting the stability of the product.
For start-up companies on manufacturing of cosmetic creams and lotions in the beginning. There are three optional types of KOS emulsifying mixer for choosing as follow. the basic manufacturing process of them is same. users can choose a suitable one according to their purpose and capacity requirement.
• Labrotary Emulsifying Mixer
• Pilot Vacuum Emulsifying Mixer
• Small-scale Batch Emulsifying Mixer
KOSBEST multifunctional laboratory vacuum emulsifying mixer accepts laboratory staff to do a vast range of testing on different emulsion products. modular design gives you more possibilities to change the equipped configuration to suit your different testing needs.
KOSBEST polit vacuum emulsifying mixer allows manufacturers to test their mixtures under production-like conditions in the laboratory. It helps our customers obtain pilot results that can be extrapolated for larger scale production. this equipment transposes your test formulations to ones that will be ready for industrial production. With it, you can test your dispersion, emulsification, and homogenization processes.
KOSBEST small-scare batch vacuum emulsifying mixer is common one equipment used in cosmetic industry for a start-up manufacturer. It has a small footprint, multi-functions and easy to operate. as a non-standard product, you can get free customization options from us to suit your different production needs.
Note: focus on data of “working volume” when you checking your batch capacity required.
