What are the advantages of carbomer in gel
Carbomer is a white, loose powder with strong hygroscopicity and soluble in water, ethanol and glycerin. When we use carbomer, we put it into water or other polar solvents and dissolve it to make carbomer gel. In this way, carbomer is mainly used as a thickener, suspending agent, adhesive, gel matrix and matrix material of sustained and controlled release formulations, etc. The usual concentration is 0.1% to 3%, and at a very low dosage (0.25 %～0.5%) can produce high-efficiency thickening effect, so as to prepare gel formulations with a wide range of viscosity and different rheology.
1. Gel for skin
Since carbomer gel is easy to apply and can absorb tissue exudate, it is beneficial to the exclusion of secretions, and is particularly suitable for the treatment of seborrheic skin diseases.

2. Eye gel
Ordinary ophthalmic drugs stay in the eyes for a short time. Due to the blinking of the eyelids and the secretion of tears, only 1% to 10% of the drugs can penetrate the cornea, and the bioavailability is low. The ophthalmic gel made of carbomer can prolong the residence time of the drug in the cornea, thereby increasing drug absorption and prolonging the action time.
3. Oral gel
The carbomer gel matrix has good adhesion and film-forming characteristics, and the carbomer 940 is used as the matrix to develop a potassium oxalate gel with a certain viscosity and adhesion, which can significantly extend the drug The retention time in the oral cavity increases the efficacy. The tea polyphenol oral gel is prepared with carbomer 940 and glycerin as a matrix, which is used to kill oral bacteria. The gel has stable properties, accurate content, and is convenient to prepare and use.
4. Gel for ultrasound diagnosis
Carbomer 940 can be used as the main matrix for the preparation of coupling agent. The finished product gel has the advantages of no toxic and side effects on human skin, no damage to the probe, no pollution to clothing, smooth spreading, suitable viscosity, and stable preparation. Carbomer 940 is used as the main substrate to develop ultrasound diagnostic gel. It has been confirmed by clinical use that various quality indicators have reached the predetermined effect.
The gel has the characteristics of simple preparation, stable quality, strong adhesion, and enhanced drug efficacy. As a new type of polymer material, carbomer has excellent quality in daily chemicals and pharmaceutical excipients. It is used for preparing gels. The ideal excipient. Carbomer has strong moisture absorption. Be sure to seal it when storing, and be careful not to absorb moisture and agglomerate in the air. If there is slight agglomeration, lightly tap and press, it can become a loose powder without affecting the thickening effect. Once the product is started, it is best to place it in a sealed container with a desiccant.
