In the field of modern daily chemical and pharmaceutical products, there is a mysterious “formulator” who quietly plays a crucial role – Carbomer. This seemingly ordinary white powder is actually a secret weapon for blending product texture and enhancing user experience. Imagine that whether it’s the moisturizer you use on a daily basis or the ointment you use to relieve discomfort, the reason why they can have just the right thickness, silky but not greasy, is inseparable from the “thickening wizard” behind Carbomer.
Carbomer is a high molecular weight polymer composed of acrylic acid bonded allyl sucrose or pentaerythritol allyl ether. It can be neutralized with alkaline substances to form transparent gel, which can produce high thickening effect at a very low dosage.
Function of Carbomer:
Has hydrophilic properties and can be dissolved in water, ethanol, and glycerol.
Due to its special molecular structure, it can absorb a large amount of water and form gel shape, which has thickening, suspension and stability effects.
Has a certain affinity with the skin, can reduce the damage of irritating substances to the skin and mucous membranes, and has a protective effect on the skin.
In addition, Carbomer also has good heat and cold resistance. Being able to maintain the performance and stability of the product at different environmental temperatures, ensuring that it can achieve optimal skincare results in various environments. It can be said that Carbomer plays an indispensable role in cosmetics.
Application in slow-release and controlled release formulations:
Carbomer forms a unique network structure due to the covalent cross-linking between chains. After hydration and expansion, it forms a gel, which is used as a hydrogel skeleton material in slow release and controlled release preparations. The drug release is controlled through the formed gel layer.
● Taste masking particles:
The acidity of carbomer can mask the bitterness of alkaline drugs.
Cosmetics and personal care products:
Such as facial mask, gel cream, face cream, shampoo, shower gel, which are equivalent to ointment in medicaments.
