Carbomer 940 polymer is a white powder, crosslinked polyacrylic acid polymer.
Carbomer 940 is an extremely efficient rheology modifier capable of providing high viscosity and forms sparkling clear gels or hydro-alcoholic gels and creams.
Carbomer 940's short flow, non-drip properties are ideal for applications such as clear gels, hydroalcholic gels, and creams.
Carbomer 940 is a polyvinyl carboxy polymer used as a viscosity enhancer, gelling agent, or suspension agent.
Carbomer 940 is cross linked with ethers of pentaerythritol, and is used primarily in systems where sparkling clarity or a sharp viscosity response is required.
Carbomer 940 will impart unbelievalbe softness and glide, comparable to the glycols, when added to your formulations.
Carbomer 940 can be used to thicken surfactant systems, and to create suspension products.
Carbomer 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.
Carbomer 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 Carbomer 940 is not influenced in this way.
Carbomers are thickening agents that help control the viscosity and flow of cosmetic products.
Carbomer 940 also help distribute and suspend insoluble solids into liquid, and prevent the oil and liquid parts of a solution from separating
Carbomer 940 is a cross-linked polyacrylate polymer, which can produce high viscosity and can form a transparent gel.
Carbomer 940 has important uses such as thickening and suspension. It has a short process (no drip).
Simple, good stability, widely used in transparent gel, essence and cream products, especially suitable for highly transparent products
Uses of Carbomer 940
Cosmetics like gels, scrubs, and Soap Making
Commonly used in anti-aging creams, eye creams, exfoliant scrubs, shampoo, thickening agents, and viscosity boosters.
Storage-Keep in a cool (preferably below 85°F, the cooler the better), dark and dry store-room.
Shelf Life
Under optimal storage conditions, in original unopened drums/containers, minimum two years.
Typical use level 0.1-0.5% depending on the type of viscosity results in the formulation desired.
Carbomer 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)
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.
Applications of Carbomer 940
The dominant application for Carbomer 940 is as a superabsorbent.
About 25% of PAA is used for detergents and dispersants.
Polyacrylic acid and its derivatives are used in disposable diapers.
Acrylic acid is also the main component of Superadsorbent Polymers (SAPs), cross-linked polyacrylates that can absorb and retain more than 100 times of their own weight in liquid.
Detergents often contain copolymers of acrylic acid that assist in sequestering dirt.
Cross-linked polyacrylic acid has also been used in the processing of household products, including floor cleaners.
Carbomer 940 may inactivate the antiseptic chlorhexidine gluconate.
The neutralized polyacrylic acid gels are suitable biocompatible matrices for medical applications such as gels for skin care products.
Carbomer 940 films can be deposited on orthopaedic implants to protect them from corrosion.
Crosslinked hydrogels of Carbomer 940 and gelatin have also been used as medical glue.
Other applications involve paints and cosmetics.
Carbomer 940 stabilize suspended solid in liquids, prevent emulsions from separating, and control the consistency in flow of cosmetics.
Carbomer codes (910, 934, 940, 941, and 934P) are an indication of molecular weight and the specific components of the polymer.
For many applications Carbomer 940 are used in form of alkali metal or ammonium salts, e.g. sodium polyacrylate.
Emerging applications of Carbomer 940
Hydrogels derived from PAA have attracted much study for use as bandages and aids for wound healing.

Description of Carbomer 940:
Carbomer 940 has the characteristics of short rheology, high viscosity, high clarity, low ion resistance and shear resistance.
Carbomer 940's role in the product is mainly reflected in three aspects: thickening, suspension and emulsification.
Carbo 940 can not produce higher viscosity when the content is very low (normal dosage is 0.25-0.5%).
Carbo resin can be used as an excellent suspending agent to suspend insoluble components in the system; Carbomer 940 can also be used as an emulsifier to emulsify and stabilize in the oil/water phase.
In addition, Carbomer 940 is also a transparent base for cosmetics.
Carbomer 940 is also an effective water-soluble thickener
There are still many specification carbomer product, like carbomer 941, carbomer 934, carbomer 980, carbopl 2020 etc.
Carbomer is a cross-linked acrylic polymer, which swells in water and adds a small amount of neutralizing agent.
Such as: in the case of neutralizer and neutralizer 2), a highly transparent gel is formed. Carbomer has different models.
For example: Carbomer 940 has short rheological properties, and the viscosity reaches 63000MPA.S at 0.5%.
Carbomer 940 is suitable for products with high viscosity.
Carbomer 941 has long rheology.
Performance, at 0.5% viscosity up to 7500MPA.S is suitable for low-viscosity products, carbomer corresponding models have ion-resistant and ion-resistant performance, daily chemical industrial products.
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 it 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.
Even if the defoamer is added, it is difficult to eliminate the air bubbles.
