Carbopol: Key ingredient for improving the performance of hand sanitizer

In the field of personal hygiene and cleaning products, hand sanitizer has become an indispensable part of daily life. Especially for hand sanitizers, they are favored by consumers due to their convenience and rapid sterilization effect. Among numerous ingredients, carbomer plays a crucial role as an important thickener and stabilizer in improving the performance of hand sanitizers. This article will explore the application of Carbopol in hand sanitizers and the many benefits it brings.

Basic characteristics of Carbopol

Carbopol is a polymer with the chemical name polyacrylic acid, and its molecular structure contains a large number of carboxylic acid groups. These groups enable Carbomer to form high viscosity gel in water, with good thickening, suspension and stability. In addition, Carbopol also has certain emulsifying ability and biological adhesion, making it widely used in cosmetics and pharmaceuticals.

The role of Carbopol in hand sanitizer

In the formula of hand sanitizer, Carbopol mainly plays the following roles:

1. Thickening and Stability

Carbopol can significantly increase the viscosity of hand sanitizer, making it easier to use and control. At the same time, it can also stabilize other ingredients in the formula, prevent layering and precipitation, and ensure the uniformity and consistency of the product. For example, in the formula of a hand sanitizer, the addition of Carbopol between 0.3% and 0.5% can effectively improve the texture and stability of the product.

2. Improve user experience

The gel formed by Carbomer is fine and smooth when applied on the hand, easy to push and absorb. It can form a uniform protective film on the hands of hand sanitizer, not only enhancing the sterilization effect, but also avoiding stickiness and improving the user's experience.

3. Enhance sterilization effect

The biological adhesiveness of Carbopol enables it to prolong the residence time of hand sanitizer on the skin surface, thereby enhancing the effectiveness of the antibacterial ingredients. In addition, it can also work synergistically with other ingredients in the formula to improve overall bactericidal performance. For example, the addition of Carbopol can further enhance the bactericidal effect and prolong the action time in hand sanitizers containing modified soy peptides and polysaccharides from Paeonia lactiflora.

4. Mild and non irritating

Carbopol has good skin compatibility, no irritation to the skin and mucous membranes, and no allergic reactions. This makes hand sanitizers containing carbomer suitable for people of all skin types, especially children and those with sensitive skin. At the same time, it can also reduce the irritation of other ingredients in hand sanitizer to the skin and protect the skin barrier function.

According to relevant patent materials, the formula of a wash free hand sanitizer contains modified soybean peptide, pinus polysaccharide, glycerin, carbomer, triethanolamine, vitamin E, rose essence, etc. Among them, the amount of carbomer added is 0.3% to 0.5%. This hand sanitizer not only has excellent bactericidal effect, but also has a long duration of action. After use, the skin feels gentle and non irritating, and is highly praised by consumers.

In practical application, Carbomer has good compatibility with other ingredients and can form a stable gel system. Its thickening effect makes it easier to control the amount of hand sanitizer used, avoiding waste. Meanwhile, the biological adhesion of Carbopol can also prolong the residence time of hand sanitizer on the skin surface, thereby enhancing its bactericidal effect.
