How to use carbomer 940 and matters needing attention,How do you make clear gel with Carbomer 940?
Everyone knows that carbomer resin is a very good suspending agent, stabilizer, emulsifier, and also the most effective water-soluble thickener. Based on these characteristics, it is destined to have an inseparable connection with our daily lives! It can be found in daily life care products, as large as our women’s cosmetics and skin care products.
Since it is so widely used, do you know what its methods of use and precautions are? Let's talk about it next.
How to use
1. Carbomer 940 direct use method
Slowly sieve the carbomer into the rapidly stirred water, fully disperse it and blend it into the water, stir continuously, pour the water phase into the oil phase and neutralize it with a suitable alkali, mix quickly to reduce the size of the particles, and you can get a shiny If the product is ready, the homogenization method can be used, but high-speed shearing will make the emulsion unstable.
2. Carbomer 940 indirect use method
Disperse the polymer emulsifier in the oil phase and continue to stir until a smooth and uniform dispersion is formed. Add an appropriate amount of alkali to the water as a neutralizer. After vigorous stirring, add the oil phase (containing polymer) to the water phase. , Continue to stir until a white emulsion is formed
Matters needing attention
|2||The thickening rate decreases|
1. Reduced solubility
Due to the special structure of carbomer, it is easy to swell in contact with water, and it is very hygroscopic, so when putting the carbomer, it should be slowly sieved and stirred quickly to make it dissolve quickly and not form a cluster.
2. The thickening rate decreases
When the ionic strength in the medium increases, the repulsive force between the negative charges in the carbomer molecules will be offset due to the increase in the cation concentration, and the formed colloid or emulsion structure will be affected, and the thickening efficiency will be reduced. It can minimize the existence of ions; increase the concentration of carbomer resin to overcome the influence of electrolyte; select granulated or encapsulated salt to reduce the ionization of soluble impurities.
3. Decreased transparency
Carbomer gel is essentially a polymer aqueous solution. The reason why the polymer solution is stable is that there is a hydration film on the surface of the particle. The addition of a strong hydrophilic non-electrolyte (such as ethanol) will increase the The molecular solution is flocculated, and the carbomer ethanol gel is prepared by different operation processes. The high limit of the ethanol concentration of the finished product is different. When the ethanol concentration is too high, the finished gel will produce a little opalescence and reduce the transparency of the gel.
