What is Carbomer 940 used for? CARBOPOL 940 Thickener. Carbopol 940 type thickener, is a carbomer. It is a ph-sensitive gelling thickener useful for formulating crystal clear gels as well as stabilizing emulsions. It is an extremely efficient rheology modifier capable of providing high viscosity and forms sparkling clear gels or hydro-alcoholic gels. Carbomers is safe in a wide variety of product types including skin, hair, nail, and makeup products, as well as dentifrices, 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,carbomer 940.

Conclusions: Carbomer gel was more efficacious than was placebo in improving a number of subjective and objective symptoms of moderate-to-severe dry eye syndrome. The results of this study indicate that carbomer gel was a safe as was the placebo,Carbomers are versatile and stable rheology modifiers but are synthetic and cannot be formulated in a natural-claimed product. Carbomers are a series of polymers that derive from acrylic acid. Companies use them in a range of products as emulsifiers, thickeners, suspenders, and binders. Research suggests that they are generally nonirritating on the skin. Health experts generally consider carbomers safe and nontoxic for humans What are the side effects of carbomer? Blurred vision, eyelid margin crusting, corneal irritation, increased lacrimation; periorbital and conjunctival oedema; ocular discomfort, pain, pruritus, and hyperaemia; contact dermatitis.
