Carbomer has emulsifying, thickening, and suspending functions, and can be used in cosmetics, hand-free gels, pharmaceutical preparations, and other fields.

Taking Carbomer 980 as an example, the steps to configure it into a gel are as follows:
1. According to actual production requirements, add Carbomer to deionized water to dissolve without stirring. After Carbomer absorbs water naturally, the solution should be free of white powder and agglomerates.
2. After stirring evenly, add a neutralizer (Carbomer: neutralizer = 1:1, or Carbomer: 5% neutralizer solution = 1:1.4) to adjust the pH value to around 7 to achieve a thickening state.
3. Use a circular tool or disperser to stir evenly at low speed.
4. Add the above solution to a homogenizer until no white agglomerates are visible.
5. After adding a neutralizer and forming a gel, use a vacuum emulsifier to remove the air in the gel.

So how can we improve the stability of Carbomer during its preparation?

In general, we can consider the following aspects:
1. Choose the right carbomer model: Different carbomer models have different viscosities and stability.

According to your specific application needs, choosing the right carbomer model can improve the stability of the gel.
2. Control pH: The stability of carbomer is closely related to pH.

Make sure that the buffer system used can stabilize the pH value within a suitable range, generally 5.0-7.0.
3. Optimize the formula: Reasonably match other excipients, such as moisturizers, preservatives, etc., to improve the stability of carbomer gel.

At the same time, avoid using ingredients that may interact or be incompatible with carbomer.
4. Control temperature: Temperature changes may affect the stability of carbomer gel. During production and storage, try to avoid drastic temperature fluctuations.
5. Stirring speed and time: The speed and time during stirring will also affect the stability of carbomer gel.

Stirring too fast or for too long may cause the destruction of the gel structure. The stirring speed and time should be adjusted according to the specific situation.
6. Packaging and storage: Choose appropriate packaging materials to prevent carbomer gel from being affected by external factors, such as light, moisture, etc. When storing, follow the recommendations on the product instructions and store it in a dry, cool place.
The above are some methods to improve the stability of carbomer gel. The specific measures may vary depending on the characteristics and requirements of the product.

In practical applications, it is recommended to conduct sufficient experiments and stability studies to determine the relevant formula and production process.

When preparing carbomer gel, you must choose high-quality High Shear Emulsifier. The vacuuming effect and stirring effect determine the stability of carbomer! This is the only way to make a very good carbomer gel!
