CARBOPOL 940

Carbopol 940's short flow, non-drip properties are ideal for applications such as clear gels, hydroalcholic gels, and creams.
Carbopol 940 is a polyvinyl carboxy polymer used as a viscosity enhancer, gelling agent, or suspension agent.
Carbopol 940 is cross linked with ethers of pentaerythritol, and is used primarily in systems where sparkling clarity or a sharp viscosity response is required.

Carbopol 940 will impart unbelievalbe softness and glide, comparable to the glycols, when added to your formulations.
Carbopol 940 can be used to thicken surfactant systems, and to create suspension products.

Carbopol 940 is excellent when you need to suspend heavy particles.
Viscosity actually has nothing to do with the ability of a product to suspend items such as jojoba beads or capispheres.

For instance, a shower gel as thick as jello will allow the beads to either sink or rise while a water thin product that contains Carbomer can suspend ball bearings.
This is because the Carbomer forms a Network that can trap and suspend the beads very effectively.

Carbopol 940 can also be used to create gel products very easily and cost effectively and Carbomer viscosity stands up to the incorporation of different fragrance and essential oils much better than standard surfactant thickeners.
When surfactant thickeners are used, fragrance and essential oils can get into the middle of the micellar structure of the gel formed and interfere with the structure to have a dramatic effect on surfactant system stability.

By contrast, the network created by Carbopol 940 is not influenced in this way.
Carbomers are thickening agents that help control the viscosity and flow of cosmetic products.

Carbopol 940, also called Carbomer or Carboxypoly-methylene is a generic name for synthetic high molecular weight polymers of acrylic acid used as thickening, dispersing, suspending and emulsifying agents in pharmaceuticals and cosmetics.
They may be homopolymers of acrylic acid, crosslinked with an allyl ether pentaerythritol, allyl ether of sucrose or allyl ether of propylene.

Carbopol 940 also help distribute and suspend insoluble solids into liquid, and prevent the oil and liquid parts of a solution from separating.
Carbopol 940 is a cross-linked polyacrylate polymer, which can produce high viscosity and can form a transparent gel.
Carbopol 940 has important uses such as thickening and suspension.

Carbopol 940 has a short process (no drip).
Simple, good stability, widely used in transparent gel, essence and cream products, especially suitable for highly transparent products.

Carbopol 940 must be thoroughly mixed and hydrated.
Increasing the pH to >6.0, gives a gel structure.

Neutralization can be carried out with inorganic bases such as NaOH or KOH, or Triethanolamine (TEA).
For external use only.

When carbomer is dispersed into water and neutralized with an approbate base (NaOH, KOH, N$4OH, or organic amine such as Triethanolamine (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.

To 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)
Carbopol 940 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, Carbomer is an anionic polymer, i.e. many of the side chains of Carbomer will lose their protons and acquire a negative charge.
This makes Carbomer polyelectrolytes, with the ability to absorb and retain water and swell to many times their original volume.

Dry Carbomer 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.

Compatability of Carbopol 940:
Because Carbopol 940 is anionic viscosity is affected by cations (especially sodium) and you will need to neutralize prior to the addition of other phase ingredients to minimize the impact, otherwise neutralize final formulation.

Neutralization of Carbopol 940:
Solution will not fully thicken until neutralized (pH raised).

Method of dissolving carbomer:

Pre-soaking method:
24 hours in advance, the carbomer should be added in the removal according to actual production requirements
Dissolve in the sub-water without stirring.

After the carbomer naturally absorbs water, there is no whiteness on the surface.
Color powder, the solution does not see white agglomerates, whichever is the case, stir evenly, and then add the neutralizer.

Adjust the PH value to about 7 to reach the thickening state, use a circular tool or a disperser, and stir evenly at low speed.
The homogenizer is added to the homogenizer according to the actual production ratio, and no white masses can be seen in the homogenizer, add after the neutralizer has formed a gel, use a vacuum emulsifying pot to remove the air from the gel.

If you use common methods to dissolve carbomer and add Carbopol 940 to water, you can't stir it.
For example, adding and stirring will make carbomer form a white water ball.

The surface has absorbed water but no water can be absorbed inside.
After neutralization, you can see a lot of water.
The water has white spots and a large number of bubbles are formed.

The carbomer viscosity is high, and the bubbles are difficult to eliminate by themselves.
