Carbomer 940, also called CarbCarbopol, 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.
They may be homopolymers of acrylic acid, crosslinked with
an allyl ether pentaerythritol, allyl ether of sucrose or
allyl ether of propylene. Carbomers are found in the market
as white and fluffy powders. They have the ability to absorb,
retain water and swell to many times their original volume.
Carbomers codes (910, 934, 940, 941 and 934P) are
an indication of molecular weight and
the specific components of the polymer
Application of Carbomer 940
Carbomer is used for topical formulations and suitable
for preparation of gels, creams and coupling agent.
Carbomer and cross-linked acrylic resin as well as series
products of these cross-linked polyacrylic acid are widely
used at present and are often used in topical lotion,
cream and gel. In a neutral environment,
Carbomer system is an excellent gel matrix
with crystal appearance and nice sense of touch,
