Demonstrating PN-100 Anti-Redeposition and Stain Removal in Laundry Applications

In our last blog post, we explored PN-100 — a polyethyleneimine ethoxylate that is an excellent high-performance additive for detergents and cleaners. Expanding on its features and benefits, let’s take a look at test results that point to its anti-redeposition performance and excellent stain-removing capabilities in laundry applications.

Anti-Redeposition Performance

Test results demonstrate the anti-redeposition performance of PN-100 at low temperatures. We added a washing solution containing 8 parts per million (ppm) of PN-100 to a mixture of anionic and nonionic surfactants, which are used in general formulations for laundry detergent. We then washed cotton garments, contaminated with natural clay, three times at 25°C. According to the results (Figure 1), PN-100 helps to retain the garment’s original whiteness compared to other solutions.

The results also show PN-100’s ability to reduce the surfactant dosage in detergents by up to 50 percent without any decrease in performance, enabling formulators to improve the cost effectiveness of their detergents.

Excellent Stain Removal

PN-100 can also improve a detergent’s ability to remove stains — even at low temperatures. We added a washing solution containing 8 ppm of PN-100 to a mixture of surfactants, then washed cotton garments contaminated with natural clay and oily soil at 25°C. The results of the test (Figure 2) demonstrate the resulting stain removal performance. Specifically, the PN-100 solution demonstrated better stain-removing capabilities than solutions without any polymer condition.
