Carbomer 940 is an easy to use water soluble polymer, used as an emulsifying, stabilizing, suspending, thickening and gelling agent, widely used in many applications due to its versatility and safety.
A very easy to use gel/ thickener. Carbopol 940 polymer thickener is a cross-linked polyacrylate polymer. It is a very efficient thickener (rheology modifier) providing high viscosity and clear water or hydroalcoholic for making a variety of gels and creams.
The properties of Carbopol 940 type polymer short flow (non-drip) are great for applications where you are making clear gels, hydroalcoholic gels, creams. Widely used due to their versatility and safety.
Features and Benefits of Carbomer 940 type powder Polymer for thickening:
- Short flow properties
- High clarity
- High viscosity
- High suspending ability
- Hair styling gels
- Hydroalcoholic gels
- Moisturizing gels
- Bath gels
- Hand, body and face lotions
- CreamsNormal / typical usage is 0.1 – 1.49 % depending on the viscosity / thickness desired.Appearance – White PowderWhen carbomer is dispersed in to water and neutralized with an approbate base (NaOH, KOH, NH4OH, or organic amine such as Triethanalamine commonly called TEA, AMP, AMPD) an opalescent gel is formed. Dispersion should be made by slow addition of the polymer in order to avoid the formation of lumps and stirring until all particles are completely hydrated. Use of magnetic stirrer is preferred, but hand mixing is alsoTo neutralize 1 g of of the carbomer to pH 7 ca. .0.01 equivalent of base are required (e.g. 0.4 g of NaOH, 1.5 g of TEA) It is advisable to add strong bases previously diluted in to water at a concentration not higher than 10%.Poly(acrylic acid) (PAA or Carbomer) is a generic name or term for the synthetic high molecular weight polymers of acrylic acid. These may be homopolymers of acrylic acid, crosslinked with an allyl ether pentaerythritol, allyl ether of sucrose or allyl ether of propylene. And, in a water solution at neutral pH, PAA is an anionic polymer, i.e. many of the side chains of PAA will lose their protons and acquire a negative charge. This makes PAAs polyelectrolytes, with the ability to absorb and retain water and swell to many times their original volume. Dry PAAs are found in the market as white and fluffy powders. Carbomer codes (like 940 for example) indicate the molecular weight and the specific components of the polymer typically .
Please note Carbomer 940 is not self wetting and will take several hours of continuous mixing for this product to gel. The use of a magnetic mixer is very helpful when mixing this product. TEA is not required all the time so please use a PH meter to ensure PH level is 7.0-8. 940 carbomer will have a slightly yellow appearance. Many of our customers add aloe gel to the formula in 0.1-0.2% so the colour of the final product is thought to be because of the gel.
