Carbomer

Carbomer is a synthetic polymer widely used in the cosmetics and pharmaceutical industries for its thickening and gelling properties. It is particularly popular in the formulation of gels, creams and lotions due to its ability to create viscous textures. Here are some key points to know about Carbomer:

Characteristics :

• Polymer Structure : Carbomer belongs to the acrylic polymer family. It is often available as a white powder.
• Hydrophilic: It is hydrophilic, which means it has a strong affinity for water.
• Neutralization: It is generally added in acid form to formulations and must be neutralized (often with alkaline agents such as triethanolamine) to activate its thickening power.
• Texture: It gives formulations a gel-like or creamy texture, improving product stability and viscosity.

Common uses :

• Cosmetics: Used in a variety of cosmetic products such as face creams, shower gels, shampoos, body lotions, etc.
• Pharmaceutical: Found in some pharmaceutical formulations, including topical gels and oral medications.
• Personal Care: Also found in personal care products such as hand sanitizers.

Precautions for use :

• Precise neutralization: Carbomer must be neutralized precisely to achieve the desired consistency in the formulation.
• Compatibility: Compatibility with other ingredients must be taken into account when formulating products.
• Storage: Carbomer-containing products should be stored at appropriate temperatures to avoid texture changes.
• Stability testing: Carbomer-containing formulations often require stability testing to ensure performance under different conditions.

It is important to note that Carbomer may be available under different names such as Carbomer 934, Carbomer 940, etc., depending on its viscosity and specific properties.

Manufacturers of cosmetic and pharmaceutical products must comply with local regulations and follow the specific recommendations of the manufacturer of the Carbomer used in their formulations.
