Ever wondered how those luxurious, stable, and perfectly textured gels in skincare products are created? In this article, you'll discover the pivotal role of Carbopol 980, a key polymer for formulators, in achieving impeccable gel formulations. We'll delve into its technical advantages, best practices for use, and how it compares to other gelling agents. By the end, you'll have a clear blueprint for leveraging this ingredient to enhance your product line's performance and stability.
What is Carbopol 980?
Carbopol 980 is a high-purity, high-performance cross-linked polyacrylic acid polymer specifically designed for use in personal care and skincare formulations. It belongs to the family of Carbopol homopolymers, renowned for their ability to create clear, elegant, and stable gels. Unlike some thicker variants, Carbopol 980 is particularly favored for creating low-viscosity, sprayable, or easily spreadable gels with excellent suspension properties and a smooth, non-tacky feel upon application—a critical factor for superior user experience.
Why Carbopol 980 is a Formulator's Choice for Gels
Unmatched Clarity and Aesthetics
For transparent gel products like aloe vera gels, serums, or hydrogels, clarity is non-negotiable. Carbopol 980 disperses and neutralizes to form crystal-clear gels, providing a visually appealing product that consumers associate with purity and efficacy.
Superior Rheological Control
You have precise control over the viscosity. By adjusting the concentration and neutralization level, you can achieve anything from a light, flowing gel to a more structured one, perfect for a range of products from sprayable sunscreens to thicker after-sun gels.
Enhanced Stability and Suspension
It provides excellent suspension of active particles, insolubles, and even sodium hyaluronate, preventing settling during shelf life and ensuring uniform dose delivery.
Best Practices for Using Carbopol 980 in Your Formulations
To unlock its full potential, follow these key steps:
- Dispersion: Sprinkle Carbopol 980 slowly into the water phase under high-shear mixing to prevent lump formation.
- Hydration: Allow sufficient time for full hydration; the mixture will appear milky initially and become clear upon neutralization.
- Neutralization: Use a neutralizing agent like TEA, NaOH, or AMPD to achieve the desired pH (typically 5.5-7.0) and final viscosity. This step transforms the dispersion into a clear gel.
- Addition of Actives: Heat-sensitive or delicate active ingredients, such as vitamins or botanical extracts, should be added after neutralization at low-shear mixing to maintain their integrity.
Carbopol 980 vs. Other Gelling Agents
Choosing the right polymer depends on your product goals. While Carbopol 980 excels in clarity and light feel, other AHUALYN polymers serve different purposes:
- Carbopol 940: Ideal for creating very high-viscosity, brilliant clarity gels (e.g., high-end hair gels or super-thick treatment gels).
- Carbopol U20: A lightly cross-linked polymer perfect for ultra-low viscosity, sprayable formulations and emulsions requiring rheology modification.
- Cellulose Derivatives: Offer good thickening but often lack the crystal-clear clarity and suspension stability of Carbopol polymers.
Formulation Inspiration: A Simple Carbopol 980 Gel Base
Phase A:
Deionized Water - q.s. to 100%
Carbopol 980 - 0.5% - 1.0% (adjust for desired viscosity)
Phase B (Neutralizer):
Triethanolamine (TEA) - q.s. to pH 6.5-7.0
Phase C:
Preservative, Fragrance, Active Ingredients (e.g., 1% Sodium Hyaluronate for hydration)
This base can be adapted for soothing aloe gels, custom serum formulations, or cooling after-treatment gels.

FAQs on Carbopol 980 and Skincare Formulation
1. Can Carbopol 980 be used in combination with salts or electrolytes?
Carbopol 980 is sensitive to polyvalent ions. High concentrations of electrolytes can reduce viscosity. For formulations containing salts, pre-testing is recommended, or consider using a salt-tolerant polymer like Carbopol U20.
2. Is Carbopol 980 suitable for organic or natural claim formulations?
While it is a synthetic polymer, it is widely used in "natural-inspired" products due to its safety and efficacy. For certified organic formulations, you would need to verify with your certifying body and explore naturally derived gellants.
3. What is the typical usage level of Carbopol 980 in a gel?
Usage levels typically range from 0.1% to 1.0%, depending on the desired viscosity. A 0.5% concentration is a common starting point for a medium-viscosity gel.
4. How does AHUALYN ensure the quality of its Carbopol products?
AHUALYN supplies pharmaceutical and cosmetic-grade polymers, including Carbopol 980, with consistent batch-to-batch purity, backed by comprehensive Certificates of Analysis (CoA) to ensure your formulations are reliable and reproducible.
