How to Use AccessTHIX 880 in Your Formulations
Understanding AccessTHIX 880
AccessTHIX 880 is a powerful thickener that gives your water-based products the perfect texture. In its powder form, it’s made of tightly coiled molecules. When you mix it into water, it disperses and hydrates. But the real magic happens when you neutralize it—that is, when you raise the pH of the mixture. This causes the molecules to uncoil and stretch out, forming a complex network that traps water. This network is what turns your thin, watery liquid into a thick, stable gel or lotion.
For the more technical-minded, AccessTHIX 880 is a high-molecular-weight, cross-linked polyacrylic acid polymer (Carbomer). Neutralization deprotonates carboxylic acid groups along the backbone, creating electrostatic repulsion that expands the polymer and rapidly increases viscosity. A key advantage of AccessTHIX 880 is that it is polymerized without the use of benzene, meeting modern safety and regulatory standards for cosmetic ingredients.
Formulation Tips
Dispersion: Evenly disperse the powder into your water phase before adding other ingredients. Sprinkle slowly into a strong vortex or sieve while mixing to prevent clumps (“fish eyes”).
Hydration: Allow full hydration (a few minutes to ~30 minutes). The mixture will be slightly viscous, cloudy, and at a low pH (around 3.0).
Neutralization: Add a base gradually to a target pH of ~6.0–7.5. Common neutralizers include a 10% Sodium Hydroxide (NaOH) solution or Triethanolamine (TEA). Viscosity will build instantly and the gel will become clear.
Use 0.1–0.3% for thin serums, 0.4–0.8% for lotions and creams, and 1.0–1.5% for thick gels. Carbomers can be sensitive to electrolytes (salts) and certain botanical extracts; if your formula contains these, you may need a slightly higher use level. For hydroalcoholic gels, pair with suitable neutralizers and adjust for final alcohol content.
Key Formulation Benefits:
- High Efficiency: Builds strong viscosity at very low usage (as low as 0.1%), improving cost-in-use.
- Crystal-Clear Gels: Produces brilliantly clear gels ideal for serums, sanitizers, and water-gel bases.
- Excellent Suspension: Stabilizes and suspends beads, pigments, or exfoliants with no settling.
- Smooth, Elegant Texture: Delivers a light, non-tacky skin feel compared to many natural gums.
- Benzene-Free: Manufactured without benzene for modern, clean, and compliant formulations.
- Versatile Application: Performs across gels, lotions, creams, serums, and hydroalcoholic systems.
