Carbomer also called Carbobol 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 .
This product is acrylic bonded allyl sucrose or pentaerythritol allyl ether polymer. Calculated on dry goods, including carboxylic acid group (-cooh) group - should be 56.0% ~ 68.0 %.
Function of Widely Used Cosmetic Grade Raw Material Hand Sanitizer Bulk Powder CAS NO 76050-42-5 Gel Carbomer Carbopol Ultrez 21/940/941/980/U20/2020
Carbopol/Carbomer has good thickening, hydropphilic gelating, viscosity,emulsifying,suspending and film-forming properties.
(1) Be made into controlled release drug as slow release material,such as ascorbic acid, aspirin, lithium, atropine sulfate, procaine, chlorpheniramine, quinine sulfate, theophylline and so on.
(2) In medicine formulations for external use,as carrier substrate, it can be applied in paste,suppository,cream,gels and emulsion ect.
(3) With its gelating,viscosity and firm-forming property, it can be used as bioadhesive in carrier substrate and drug. Because of long retention time with mucous membranes of tissue , it enhances bioavailability of drug.
(4) With its suspending capacity, it can effectively suspend insoluble ingredients to form a homogenous dispersion system when used in oral suspension. This system is safe, effective, stabilized and protected from peculiar smell, thus raising bioavailability.
1. Character:
The appearance of loose white powder, piled density of about 208 kg / m3, the glass transition temperature of 100 ~ 105ºC;. Molecule contains 56% ~ 68% of carboxyl, so a weak acid resin, 0.5% water dispersion of PH 2.7 ~ 3.5, the equivalent of 2.6± 4. Balance amount of water 8 to 10% (relative humidity 50%).
2. Carbopol Main Functions:
Thickening - - can produce a wide range of viscosity and mobility;
Suspension - - to the permanent suspension of insoluble components in the system;
Emulsion - - in the oil / water phase play a role in emulsification and stability.
3. Carbomer Thickening Mechanism:
a. salt thickening, the most common approach is to become a proper resin acid salt, so that the resin molecules are open curl caused thickening. in the water and other polar solvents, with NaOH, KOH, NH40H the class and easily form salts; weak or non-acute in acute organic amine solvent will be neutralized. When the resin used as emulsifier for the oil / water emulsion to obtain the best stability, the need for using water-soluble inorganic base resin and oil-soluble organic amine and a double in that generation are in the water and oil soluble salt, the oil phase and water phase from the bridge.
b. light key thickening, the addition of a hydroxyl in the resin to give the body, the resin molecules to give a physical and a carboxyl or hydroxyl groups to form two or more hydrogen bond and thickening, this method takes time, probably even a few from 5 minutes hours, and consistency to the highest value. PH value of these acidic substances, the dispersion temperature to 70ºC; (but not more than) can thicken faster. And a number of commonly used ethoxylated polyol reagent: a nonionic surfactants, solvents, polyols, a silane copolymer of ethylene glycol, polyethylene oxide, and fully hydrolyzed polyvinyl alcohol.
4. Packaging:
This product is packed in double non-toxic polyethylene and nylon plastic bags which is moisture and air proof(5kg/bag) and then packed in carton, 10kg/small carton, 20kg/big carton.
5. Storage:
Carbopol has strong hygroscopicity. Storage must pay attention to sealing, to guard against moisture absorption agglomerate exposed in the air, if slightly caking, pat pressure, which can become loose powder will not affect the thickening effect, this product once opened, the best home with desiccant in sealed containers.
6. Transportation:
Carbomer is polyelectrolyte, friction or extrusion resin particles with static electricity sometimes. In case of bulk resin poured, first with a broom to sweep dry, do not wash with water, or on the ground or equipment to form a very thin layer of slippery.
