Carboxypoly methylene is a synthetic, high-molecular-weight polymer of acrylic acid, crosslinked with polyalkenyl ethers or divinyl glycol, commonly used in the pharmaceutical, cosmetic, and personal care industries.
Carboxypoly methylene is part of the "Carbomer" family of polymers and is recognized for its ability to form highly viscous, transparent gels at low concentrations when neutralized with a base, such as sodium hydroxide or triethanolamine.

In its raw form, Carboxypoly methylene appears as a white, fluffy powder that is odorless and soluble in water, where it swells dramatically to create smooth, stable gels.
Carboxypoly methylene's unique rheological properties make it an ideal thickening agent, emulsifier, and stabilizer in a wide variety of applications.

In the pharmaceutical sector, Carboxypoly methylene is frequently used in topical gels, creams, and drug delivery systems, offering both controlled release and bioadhesion properties.
In cosmetics, Carboxypoly methylene is valued for its ability to impart a pleasant feel and texture in products like lotions, shampoos, and facial cleansers.

Carboxypoly methylene is highly efficient, requiring very small amounts to achieve significant viscosity, and it remains stable over a wide pH range (from 5 to 10), making it versatile for various formulations.
Additionally, Carboxypoly methylene's compatibility with a broad range of active ingredients and its ability to suspend particles and emulsify oils further contribute to its widespread use across multiple industries.

Carboxypoly methylene polymer is a white powder, crosslinked polyacrylic acid polymer. 
Carboxypoly methylene is an extremely efficient rheology modifier capable of providing high viscosity and forms sparkling clear gels or hydro-alcoholic gels and creams. 

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

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

Carboxypoly methylene 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.

Carboxypoly methylene 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 Carboxypoly methylene is not influenced in this way.
Carbomers are thickening agents that help control the viscosity and flow of cosmetic products. 

Carboxypoly methylene, 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.

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)
Carboxypoly methylene 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.

Neutralization of Carboxypoly methylene:
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 Carboxypoly methylene to water, you can't stir it.
