EasyThick not thickening shampoo formulation
Question
I am formulating a shampoo using EasyThick to increase viscosity. I added EasyThick at 3% concentration to the formula and heated it until dissolved, but the shampoo did not thicken. What could be the reason for this?

Troubleshooting EasyThick in Shampoo
It sounds like you're having trouble getting EasyThick to thicken your shampoo formula, even after heating. EasyThick is designed specifically for thickening shampoos and liquid soaps.
Based on the product information, here are a few points to consider that might help troubleshoot:
- Mixing Method and Temperature: EasyThick requires heating to at least 80°C to properly incorporate and activate its thickening properties. There are two recommended methods:
- Mix EasyThick with water first, heat to 80°C until dissolved, then add your detergents and other ingredients.
- Add EasyThick after mixing water and detergents, but you must still heat the entire mixture to at least 80°C for it to melt into the formula.
Ensure you are reaching at least 80°C and maintaining that temperature briefly to allow it to fully integrate.
- Usage Rate: You mentioned using 3%, which is the minimum recommended usage rate (3-15%). Depending on the specific surfactant system in your shampoo base, you might need a slightly higher concentration (e.g., 5-10%) to achieve the desired viscosity.
- Cooling: Thickening often becomes apparent as the formula cools down after heating. Make sure you are observing the viscosity after the shampoo has cooled to room temperature.
- Formula Compatibility: While EasyThick is versatile, the overall composition of your shampoo (types and concentrations of surfactants, salts, other additives) can affect how well any thickener performs.
Try reviewing your process, ensuring the temperature reaches at least 80°C and is held briefly, and check the viscosity after cooling. If it still doesn't thicken sufficiently, consider increasing the EasyThick concentration slightly within the recommended range.
