    AI Overview
    Carbopol® 971P NF is a lightly cross-linked, high-molecular-weight polyacrylic acid polymer supplied as a white powder. It is used in pharmaceuticals as a thickener, suspending agent, and binder, particularly prized for its ability to create bioadhesive, low-viscosity, long-flow gels and provide controlled drug release in oral or mucosal formulations. 
    Key Features and Benefits 
    • Controlled Release: Provides effective drug release control in tablets, often preferred for its efficiency in drug matrix formulation compared to more highly cross-linked alternatives.
    • Rheology Modification: Produces long-flow (flowable) gels, ideal for consistent, smooth oral liquids, lotions, and suspensions.
    • Bioadhesion: Excellent mucoadhesive properties make it suitable for oral, topical, and ophthalmic drug delivery systems.
    • Stability: Stable over a wide pH range and compatible with many active pharmaceutical ingredients (APIs). 
    Typical Applications and Usage 
    • Extended-Release Tablets: 5–10 wt% concentration.
    • Oral Liquids/Suspensions: 0.2–1 wt% concentration.
    • Topical Gels/Creams: 0.5–3 wt% concentration. 
    Comparison to Other Carbopol Polymers 
    • Carbopol 971P vs. 974P: 971P is lightly cross-linked, offering lower viscosity and better drug release control in some matrices compared to the highly cross-linked, higher-viscosity 974P.
    • Carbopol 971P vs. 71G: 971P is a fine powder, while 71G is a granular form of the same polymer, designed to improve handling and flow for direct compression tablets. 
    It is important to ensure proper, slow dispersion (e.g., using a 20-mesh screen) into water to avoid lump formation and achieve optimal hydration.

    What is the difference between Carbomer 934P and 974P?
    The sustained-release effect of 974P is stronger than that of 934P. The release rate of tablets containing 10% carbomer 974P is similar to that of tablets containing 30% carbomer 934P. In addition, factors such as the solubility of the drug and the pH value of the medium also affect the release of the drug.
