Definitions
- the invention belongs to the field of medical equipment, and particularly relates to a moisturizing and lubricating composition containing xanthan gum and its application.
- the commonly used moisturizing and lubricating factors are mainly hyaluronic acid (HA), sodium pyrrolidone carboxylate (PCA), polyvinylpyrrolidone (PVP), polyvinyl alcohol (PVA), glycerin, propylene glycol, sorbitol and so on.
- PCA is a moisturizing factor that naturally exists in the skin.
- the moisturizing and hygroscopic properties are significantly better than glycerin, propylene glycol, and sorbitol.
- the moisturizing effect of PCA must be in a high humidity environment. When the air humidity is low, it makes the skin more dry.
- PVP and PVA are high-molecular compounds. Although they are both water-soluble substances, the degree of stretch of their molecular chains in aqueous solution is not ideal, and PVA has a stimulating effect on the eyes.
- HA is an acidic mucopolysaccharide, which is also a component of the human body.
- HA has good water absorption and moisturizing properties, its production cost is high, and there are many factors affecting the moisturizing and lubricating properties, such as pH enzymes, reducing substances, ultraviolet rays, etc., and its stability is very poor. The difference in technology has a significant impact on the effect.
- Xanthan gum is a kind of microbial extracellular polysaccharide produced by fermentation using sugar as the main raw material. In 1969, xanthan gum was first approved by the US FDA for use in foods and medicines. It is now used as a pharmaceutical excipient in the 2010 version of China Pharmacopoeia has good biological safety. The literature has confirmed that xanthan gum can be used to treat eye diseases and increase the bioavailability of ophthalmic drugs.
- xanthan gum solutions have higher viscosity at low concentrations and are used as thickeners, suspending agents, emulsifiers, and stabilizers in liquid and semi-solid formulations.
- the high viscosity of xanthan gum makes it easier for external preparations to be coated, and not easy to fall off from the skin, which helps to improve the bioavailability of the drug and increase the comfort of the drug.
- xanthan gum is used as an eye drop aid to prolong the contact time between the drug and the site of application. Due to the nature of its pseudoplastic fluid, the shear force generated during blinking can rapidly reduce its viscosity without causing discomfort to the eyes.
- Eye drops prepared by mixing xanthan gum, chondroitin sulfate, and sodium hyaluronate can protect corneal epithelial cells and accelerate cell regeneration.
- the ophthalmic gel prepared with xanthan gum as the gel matrix is uniform, stable, and has good gel strength. It has a good bioadhesive effect on the corneal surface, can significantly prolong the drug residence time and improve the efficacy, and delay the drug release.
- the research results show that xanthan gum is more stable than sodium hyaluronate, is not easily degraded by enzymes and free radicals in the body, and has a longer residence time.
