Time : 2025.10.15 Page View : 33 Author : Alice

When it comes to finding a versatile and high - performance ingredient for formulating products in cosmetics, pharmaceuticals, personal care, and medical devices, Carbopol 940 (CAS NO.: 9007 - 20 - 9) stands out as a leading choice. As a star product in the Carbopol and Carbomer families, Carbomer 940 has revolutionized the way formulations achieve desired textures, stability, and functionality, making it an essential component for many daily chemical and specialty product applications.

Core Properties: Why Carbopol 940 Shines

1. Outstanding Thickening Performance

Carbopol 940 is a water - soluble polymer that delivers efficient thickening even at low concentrations (0.5% - 2%). This means it can significantly increase the viscosity of formulations. What’s more, it forms transparent to crystal - clear gels without any cloudiness or graininess, perfectly meeting the visual demands of high - end cosmetics and pharmaceutical products.

2. Superb Suspension Ability

It can stably suspend active ingredients like vitamin particles and microcapsules, preventing sedimentation and layering. This not only ensures the uniformity of the product but also extends its shelf life.

3. Broad Compatibility

Suitable for water - based and water - alcohol mixed systems (with ethanol concentration ≤ 60%), Carbopol 940 is compatible with a variety of emulsifiers, preservatives, and active ingredients. It also has a wide pH range (needs to be neutralized to 5.0 - 9.0) and quickly forms gels after neutralization with triethanolamine (TEA) or sodium hydroxide (NaOH).

Key Selling Points: What Makes Carbopol 940 Irreplaceable

Transparent Aesthetics: It’s the only Carbomer grade that can simultaneously meet the needs for high transparency and strong thickening, specially designed for essences and gel masks.
Rapid Response: Completes gelation within 5 - 10 minutes after neutralization, greatly improving production efficiency.
Stability Assurance: Exhibits excellent electrolyte resistance, with no water separation or caking during long - term storage.
International Certification: Complies with USP/NF/EP/JP pharmacopoeia standards, meeting the compliance requirements of the global market.
