How to make Carbomer gel transparent?

In the practical application of Carbomer gel, transparency is an important factor affecting product quality and market competitiveness. Whether it is cleaning products, cosmetics or disinfection products, consumers are more inclined to choose clear and transparent gel. However, when ethanol is added to Carbomer gel as an additive to enhance permeability, corrosion prevention and solubilization, it often causes a problem: too high ethanol concentration will make gel produce opalescence and reduce transparency. Don't worry! Next, I will share a set of practical methods to help you effectively improve the transparency of Carbomer gel and make the product stand out among many competing products by virtue of its outstanding appearance.

1, Ethanol: The role of a double-edged sword

Ethanol, which is an indispensable component in disinfection free gel, is very popular because of its fast volatilization and effective sterilization, and its content can even be up to 75%. However, when it is added to Carbomer gel, a polymer aqueous solution, it acts as a double-edged sword. The stability of Carbomer gel depends on the hydration film on the surface of polymer particles, and the addition of strong hydrophilic ethanol will break this balance, leading to the flocculation of polymer solution, thus affecting the transparency of the gel, resulting in opalescence in the finished product and reducing the visual attractiveness of the product.

2, Transparency challenge under high concentration ethanol

The upper limit of ethanol concentration in the final product of Carbomer ethanol gel prepared by different processes is different. But a common phenomenon is that when the ethanol concentration rises to a certain threshold, the transparency of gel will be significantly reduced, and the opalescence phenomenon will be intensified. This not only affects the aesthetic appearance of the product, but may also make consumers doubt the quality of the product. Therefore, how to maintain or improve the transparency of gel while ensuring the efficacy of ethanol has become the key to improving the competitiveness of products.

3, Scientific Proportioning: Clever Application of Purified Water

In the face of the transparency challenge brought by ethanol, a simple and effective method surfaced - slowly add 2% purified water and fully stir in the finished gel containing 70% ethanol. This operation may seem insignificant, but it actually contains scientific principles. The addition of purified water can dilute the ethanol concentration to a certain extent, reduce its damage to the polymer hydration membrane, thus reducing the flocculation phenomenon, and make the gel return to the original clarity and transparency. The experiment proved that the opalescence of the gel treated in this way was significantly reduced, and its transparency was significantly improved, bringing consumers a more pleasant visual experience.

4, Process optimization: Details determine success or failure

In addition to the purified water addition method mentioned above, the optimization of the process cannot be ignored. From the selection of raw materials, temperature control of mixing, to the speed and time of stirring, every step may affect the transparency of the final product. For example, using low-temperature slow stirring can reduce the generation of bubbles and avoid the decrease in transparency caused by bubble refraction; Precise control of the addition order and proportion of each component is the basis for ensuring the stability and transparency of the gel system.
