Thickening agent giving viscosity and stabilizing the formulation.
First launched in the nineteen fifties,it is composed of a group of polymers derived from acrylic acids. Carbomer was developed specifically to fulfill many needs in personal care. it does this a great injustice to call it a thickener only. There are plenty of ways to thicken solutions, but Carbomer not only gives the desired viscosity but it also stabilizes the formulation and gives it texture. Nearly as important as what it does, is what it doesn’t do. It has no effect on the skin at all. If you rub a neat Carbomer gel into skin, it dries completely unnoticeable. It doesn’t make skin feel tacky. It doesn’t make skin feel tight.
In organic chemistry, a carbomer is an expanded molecule obtained by insertion of a C2 unit in a given molecule. Carbomers differ from their templates in size but not in symmetry when each C–C single bond is replaced by at least one alkyne bond, and when a double bond is replaced by an allene bond. The size of the carbomer will continue to increase when more alkyne bonds are introduced and for this reason carbomers are also called carbon-molecules, where “n” is the number of acetylene or allene groups in an n-expansion unit. This concept, devised by Rémi Chauvin in 1995, is aimed at introducing new chemical properties for existing chemical motifs.
