What is the Difference Between Carbopol Ultrez 20 and 21?

Carbopol Ultrez 20 and 21 are both acrylate cross-polymers used in the cosmetic industry, but they have some differences in their properties and applications. Here are the key differences between Carbopol Ultrez 20 and 21:

1. Clarity: Carbopol Ultrez 20 does not show high clarity, while Carbopol Ultrez 21 has high clarity.
2. Applications: Carbopol Ultrez 20 is suitable for skin care, hair care, and shower or bath products, while Carbopol Ultrez 21 is suitable for clear and hydroalcoholic gels, creams, and lotions.
3. Electrolyte Tolerance: Both Carbopol Ultrez 20 and 21 have varying electrolyte tolerance, with Ultrez 20 having medium tolerance and Ultrez 21 also having medium tolerance. Electrolyte tolerance affects how fast the gel breaks on the skin; the lower the tolerance, the easier it breaks from the skin's natural salts.
4. Skin Feel: In terms of skin feel, Ultrez 10 is the lightest, followed by 30, while 20 and 21 are the heaviest.

Both Carbopol Ultrez 20 and 21 have high viscosity, stabilizing, suspending, and thickening properties. They are used in various personal care and cosmetic products, but their specific properties make them more suitable for different types of formulations.

Comparative Table: Carbopol Ultrez 20 vs 21

Carbopol Ultrez 20 and 21 are both acrylate polymer materials used in personal care and cosmetic applications. Here is a table comparing their differences:

Carbopol Ultrez 20 is an acrylate polymer material that occurs as a powder and is suitable for clear and hydro-alcoholic gel production, cream manufacturing, and lotions production for personal care and cosmetic applications. Carbopol Ultrez 21 is a polyacrylate polymer that offers high clarity, stabilizing, suspending, thickening, and high viscosity properties. It is designed for efficient thickening, stabilization, and suspension in personal care formulations. Both polymers are used in various applications, such as gels, creams, and lotions for personal care and cosmetics.
