Performance Characteristics
Solubility

The solubility of Multitrope LF10 is dependent upon both surfactant content and concentration of alkaline builders in liquid formulations. Such concentrates and their diluted solutions will display typical non-ionic cloud point behavior for NaOH built detergent systems.

When formulating liquid detergent concentrates, Multitrope LF10 surfactant can easily be added to alkaline built solutions. LF10 dissolves quickly when added to a formulation, reducing blending times. Shown below in Table 1, as the concentration of surfactant or builder increases, the cloud point of the blend will also increase. Competitive product data were included for comparison purposes.

Foaming properties

Dilute solutions of Multitrope LF10 surfactant containing detergent builders will be virtually non-foaming when evaluated at temperatures in excess of the solution cloud point. Foaming decreases with increasing temperature and builder content as shown in Table 3. A blender foam test was utilized, using 100ml of test solution containing 0.5% surfactant and varying amounts of NaOH, competitive product results are also included. The data demonstrate that, even at low temperature, the Multitrope LF-10 provides low foam.

Additional performance of Multitrope LF10 with NaOH can be seen in Table 4 below, which shows surface tension reduction and wetting times at 0.5% concentration. This degree of surface activity promotes rapid textile and hard surface wetting as measured by the Draves wetting test.

Detergency

Alkaline metal cleaning data for Multitrope LF10 is compared to a competitive product in Figure 1. In a 10 minute wash cycle at 60°C, the data show Multitrope LF10 surfactant outperforms the competitive product. The composition of Multitrope LF10 has been optimized to maximize detergency, low foaming characteristics and electrolyte tolerance. This combination of properties makes Multitrope LF10 particularly suitable for use in spray detergents and floor scrubbing formulations.

* Cleaning solution also contained 0.8% NaOH, 0.8% sodium metasilicate and 0.4% sodium carbonate.
