What is a Carbopol?
Carbopol® (Carbomer)
In the cosmetic industry, Carbopol is used as a thickener in lotions, creams and gels. It is also used to stabilize, suspend, and control the release of pharmaceutical products. At low concentrations, suspensions flow easily with a slippery feel.
What is carbomer used for?
Carbomers. Carbomers are acrylic acid polymers that are used for a variety of purposes. They are used in pharmaceutical processes as suspending agents, gel bases, emulsifiers, and binding agents. They are also used as artificial tears.
What is the chemical carbomer?
Carbomer is the trade name for polyacrylic acid. Companies use it extensively in formulations across multiple industries, including cosmetics, pharmaceuticals, and personal care. Carbomers are synthetic, crosslinked polymers of acrylic acid with a high molecular weight. Dried carbomers are lightweight, white powders.
What is sodium polyacrylate polymer used for?
Sodium polyacrylate is an absorbent polymer that is used as an emulsion stabilizer, a hair fixative, a film former, skin conditioner, and a viscosity agent [1]. You will see them as the gel like crystals in baby diapers, which are makes them absorbent.

What is the pH of Carbopol?
Carbopol is a polyacrylicacid (PAA) polymer, which shows a sol to gel transition in aqueous solution as the pH is raised above its pKa of about 5.5 [10].
Is Carbopol good for skin?
Carbomers is safe in a wide variety of product types including skin, hair, nail, and makeup products, as well as dentifrices. Application: Carbomers is safe in a wide variety of product types including skin, hair, nail, and makeup products, as well as dentifrices. It’s also best for ultrasound gel.
Is Carbopol natural?
Carbopol 940, also known as Carbomer, is a 100% synthetic thickening agent derived from acrylic acid and is so distantly removed from most natural chemical compounds that it simply doesn’t cause negative reactions on the skin.
Is Carbopol toxic?
The Carbopol® polymers, like other high molecular weight polymers, demonstrate a low toxic and irritation potential based on their physical and chemical properties.
Is sodium polyacrylate safe for skin?
The Expert Panel evaluated the scientific data and concluded that sodium polyacrylate was safe for use in cosmetics and personal care products when formulated to avoid skin irritation. Since sodium polyacrylate is a large compound, it is unable to penetrate the skin’s barrier.
What is polyacrylate made of?
Sodium polyacrylate is produced by polymerizing acrylic acid and hydrolysis of the polyacrylic acid with an aqueous sodium hydroxide solution.
Is Carbopol a polymer?
Carbopol is a high molecular weight, hydrophilic, and crosslinked polyacrylic acid polymer.
How do you make Carbopol gel?
The 100 g gel was prepared by direct dispersion method. In this firstly, propyl paraben was dissolved in water at 80ºC and then accurately weighed quantity of carbopol 940 was dispersed in water at 40ºC with constant stirring for 30 min [8].
Why does the Carbopol solution increase in viscosity with pH?
For carbomer-based gels, which are derivatives of acrylic acid, the required pH is obtained through neutralization: with increasing pH value, the globules of carbomer molecules unfold into a bulk network, creating a structure formation which increases the viscosity of the system.
Is polyacrylate a plastic?
polyacrylate, any of a number of synthetic resins produced by the polymerization of acrylic esters. Forming plastic materials of notable clarity and flexibility under certain methods, the polyacrylates are employed primarily in paints and other surface coatings, in adhesives, and in textiles.
What is polyacrylate made from?
Sodium polyacrylate is an anionic polyelectrolyte with negatively charged carboxylic groups in the main chain. Sodium polyacrylate is a chemical polymer made up of chains of acrylate compounds. It contains sodium, which gives it the ability to absorb large amounts of water.

Is polyacrylate toxic?
Superabsorbent sodium polyacrylate polymeric hydrogels that retain large amounts of liquids are used in disposable diapers, sanitary napkins, and other applications. These polymers are generally considered “nontoxic” with acute oral median lethal doses (LD50) >5 g/kg.
How do you dilute Carbopol?
Using moderate to vigorous agitation (800-1200 rpm), add the oil phase containing Carbopol® polymer to the water phase. The water phase should contain an appropriate neutralizing base. Continue to mix for 15-20 minutes until the Carbopol® polymer has swelled to produce a smooth emulsion.
