Carbomer is the trade name for polyacrylic acid PAAa group of synthetic high molecular weight polymers of acrylic acid used in cosmetics and personal care products as thickening agents.
They are primarily added to gel-like formulations, such as facial moisturizerssunscreen, shampoo, anti-aging treatments, cleansers, and scrubs, to help control the viscosity, flow, and consistency of the product. The Carbomer polymers have been used in cosmetics for over 50 years. An article from Cosmetics Info explains that the Carbomers are large molecules prepared from relatively small chemical compounds called monomes.
The monomers used to make Carbomer polymers are acrylic acid and polyalkenyl polyethers. All of the Carbomer polymers are chemically similar, differing from each other in molecular weight and viscosity. Dry Carbomer polymers come in the form of white, fluffy powders.
You may notice a number associated with the Carbomer name on the ingredient label. This is the Carbomer code. Carbomer codes i. The Carbomer polymers can have varying pH levels that must be neutralized in order for them to function as thickening agents.
Formulations that contain Carbomer polymers will sometimes have these neutralizing agents listed. Other times, companies will purchase pre-neutralized Carbomer, which may or may not list the neutralizing agent. There are claims that some of these neutralizing agents may carry contaminants that can be potentially carcinogenic.
An ingredient that is similar to the Carbomers is sodium polyacrylate, a sodium salt of polyacrylic acid. This ingredient is also used as a thickening agent and texture enhancer is cosmetics and personal care products since it is a superabsorbent polymer with the ability to absorb as much as to times its mass in water.
To understand the functions of Carbomers, it is important to first understand how they work. When a Carbomer polymer is placed in a water solution at neutral pH, many of the side chains will lose their protons and acquire a negative charge. Because of this reaction, Carbomers are able to absorb and retain water, and swell to many times their original volume. This is why Carbomers are considered to be texture enhancers and are used to add thickness to products, particularly gel-like formulations.
Additionally, Carbomers have the ability to distribute or suspend an insoluble solid in a liquid. Thus, Carbomers are used to keep emulsions from separating into their oil and liquid components, as well as to control the consistency of cosmetics and other personal care products. By adding Carbomers to things like shampoos, conditioners, creams, and lotions, formulations will appear more rich, smooth, and creamy.
Varying the amount of Carbomer used in a product allows the manufacturer to create anything from a stiff hair gel that will stay exactly where you put it, a lotion with body but which still flows easily, or a rich cream that holds it shape. According to skin care expert Paula Begoun, high amounts of carbomers in a gel may result in the product rolling or balling up of cosmetic products on skin, but this phenomenon depends on other formulary steps taken to minimize this effect.
Carbomers will not make the skin tacky, dry, or tight. In addition to use in personal care products, Carbomer polymers have a wide variety of commercial and industrial uses.There are many gelling agents.
Though each gelling agent has some unique properties, there are some generalizations that can be made:. As a group, they are dry powders, which have high bulk densities and form acidic aqueous solutions pH around 3.
They thicken at higher pHs around 5 or 6. They will also swell in aqueous solution of that pH to as much as times their original volume. Their solutions range in viscosity from 0 to 80, centipoise cps. Some examples of this group of gelling agents are:.
Carbomer polymers are best introduced into water by slowly sprinkling a sieved powder into the vortex created by rapid stirring. This should prevent clumping. Once all of the powder has been added, the stirring speed should be reduced to decrease the possibility of entrapping air bubbles in the formulation. As mentioned, when the carbomer is dispersed, the solution will have a low pH. A neutralizer is added to increase the pH and cause the dispersion to thicken and gel.
Some neutralizing agents are sodium hydroxide, potassium hydroxide, and triethanolamine. If inorganic bases are used to neutralize the solution, a stable water soluble gel is formed. If triethanolamine is used, the gel can tolerate high alcohol concentrations. The viscosity of the gel can be further manipulated by propylene glycol and glycerin to increase viscosity or by adding electrolytes to decrease viscosity. The cellulose derivatives methylcellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methylcellulose, and carboxymethyl cellulose are commonly used.
There are some commonalties in these compounds, and each one has their unique properties. The Pharmaceutics and Compounding Laboratory. Common Gelling Agents There are many gelling agents. Though each gelling agent has some unique properties, there are some generalizations that can be made: If the gelling agent is added to the dispersing medium in a haphazard manner, there is a tendency for the agent to "clump. The clumps will ultimately hydrate, but it will take more time.
A much more efficient manner is to sieve the agents onto the surface of the medium a little at a time as the medium is stirred.
Using glycerin as a wetting agent will sometimes minimize clump formation. Some gelling agents are more soluble in cold water than in hot water.Product list Traditional high-efficient rheology modifier carbomer Efficient rheology modifier for home care Traditional Long-flow Property Carbomer Improved type - easy to disperse Carbomer Improved type -self-wetting carbomer Improved type Carbomer Liquid Carbomer Pharmaceutical grade carbomer Home care carbomer High carlity traditional carbomer Benzen free carbomer Homopolymer of Vinylpyrrolidone.

They may be homopolymers of acrylic acid, or crosslinked with an allyl ether of pentaerythritolallyl ether of sucroseor allyl ether of propylene.
In a water solution at neutral pHPAA is an anionic polymeri. This makes PAAs polyelectrolyteswith the ability to absorb and retain water and swell to many times their original volume. Dry PAAs are sold as white, fluffy powders that are frequently used as gels in cosmetic and personal care products.
Their role in cosmetics is to suspend solid in liquids, prevent emulsions from separating and control the consistency in flow of cosmetics. Carbomer codes, and P are an indication of molecular weight and the specific components of the polymer. For many applications PAAs are used in form of alkali metal or ammonium salts, e. In the dry powder form, the positively charged sodium ions are bound to the polyacrylate, however in aqueous solutions the sodium ions can dissociate.
Instead of an organized polymer chain, this leads to a swollen gel that can absorb a high amount of water. Polyacrylic acid is a weak anionic polyelectrolyte, whose degree of ionisation is dependent on solution pH.

In its non-ionised form at low pHs, PAA may associate with various non-ionic polymers such as polyethylene oxide, poly-N-vinyl pyrrolidone, polyacrylamide, and some cellulose ethers and form hydrogen-bonded interpolymer complexes  In aqueous solutions PAA can also form polycomplexes with oppositely charged polymers for example, chitosansurfactants, and drug molecules for example, streptomycin.
Polyacrylic acid and its derivatives are used in disposable diapers ion exchange resins, adhesives and detergents. Detergents are often copolymers of acrylic acid that can be used in both zeolites and phosphates in washing powder formulations. They are also popular as thickeningdispersingsuspendingand emulsifying agents in pharmaceuticalscosmeticsand paints.
Cross-linked polyacrylic acid has also been used in the processing of household products, including floor cleaners. Acrylic acid is also the main component of Superadsorbent Polymers SAPscross-linked polyacrylates that can absorb and retain more than times of their own weight in liquid. PAA films can be deposited on orthopaedic implants to protect them from corrosion.
Crosslinked hydrogels of AA and gelatin have also been used as medical glue, which has a high bonding strength. For the development of polymeric matrices which allows controlled delivery rate of active substances, the recent investigations aimed towards the clarification of the conformational changes of the polymeric gel during neutralization, light irradiation, and embedment of gold nanoparticles.
Free radical polymerization is still the most common industrial for production of polymers. For the free radical polymerization of acrylic acid, most commonly thermochemical initiators such as potassium persulfate and AIBN are used. The polymerization can take several hours to complete but can be accelerated by drastically increasing the temperature and pressure.
PAA is widely used in dispersants and since the molecular weight has a significant impact on the rheological properties and dispersion capacity, it is crucial to have control over the molecular weight distribution. RAFT polymerization was used to obtain PAA with a defined molecular weight, leading to improved dispersion properties. Block copolymers of PAA have been prepared that are responsive to pH and temperature stimuli, demonstrating the possibility to be used for drug delivery purposes.
One reported approach was with surface-initiated ATRP of tert-butyl acrylate that was subsequently deprotected through pyrolysis to form the carboxylic acid. These PAA brushes can form chelate complex with silver and can therefore exhibit antibacterial activity.
