What is the Carbomer?

Carbomer is a term used for a series of polymers primarily made from acrylic acid. Carbomers are white, fluffy powders but are frequently used as gels in cosmetics and personal care products.

What is the chemical formula for acrylic acid?

C3H4O2
Acrylic acid/Formula
Acrylic acid (IUPAC: propenoic acid) is an organic compound with the formula CH2=CHCOOH. It is the simplest unsaturated carboxylic acid, consisting of a vinyl group connected directly to a carboxylic acid terminus.

Is benzene a Carbomer?

For modern carbomers synthesized using benzene-free processes, the NF has adopted the terms carbomer homopolymer, carbomer copolymer, and carbomer interpolymer to describe the various species of carbomers employed as excipients in pharmaceuticals and OTC drug formulations.

Is Carbomer good for skin?

Carbomers or PAAs are generally known to be gentle and mild on skin and are considered safe for topical application. This ingredient is known to have a low potential for phototoxicity, photo-contact allergenicity, skin irritation and sensitization at a concentration up to 100%.

Is Carbomer poisonous?

According to the Environmental Working Group, carbomers are considered to be a very safe ingredient. It is not considered to be an ingredient associated with causing cancers in “government, industry, or academic studies or assessments,” and has also not been linked to developmental or reproductive toxicity.

Is Carbomer a bad ingredient?

What is the function of Carbomer?

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 pH is acrylic acid?

Poly(acrylic acid) responds to changes in pH and ionic strength with changes in its properties; e.g., at pH < 4 precipitation occurs in aqueous solutions due to protonation of the carboxylate groups, which renders the polymer sparsely soluble in water (6) (2004) Macromolecules, 37: 7761–7766.

Is Carbomer a preservative?

15.3. Carbomers are acid-based polymers and demonstrate good mucoadhesion, particularly at low pH value where they present in a protonated state. They are high molecular weight and cross-linked acrylic polymers.

Why is Carbomer bad?

Carbomer won’t cause irritation or allergic reactions – even if a product contains up to 100% of the stuff. “Clinical studies with Carbomers showed that these polymers have low potential for skin irritation and sensitization at concentrations up to 100%.

What is the role of Carbomer codes in cosmetics?

Their role in cosmetics is to suspend 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.
