Trial Number 4

Trial Purpose:

To evaluate the longevity of the foam from a single dose of dishwashing product when used according to a neat dishwashing procedure of Green Mountain Ammenities dish soap compared to a dish soap already on the market.

Date Run:

10/02/2023

Experiment Procedure:

Two dishing washing products were selected. Testing followed CSPA DCC 18, “neat” hand dish washing test t” method. The method was selected as the supplied dishwashing products were designed to be dosed directly onto the sponge to wash.

Based on the standard, food soil was prepared at room temperature and was used immediately after making. Food soil was a mixture of soybean oil, lard, whole egg powder, potato flour, and deionized water. Cleaning performance was conducted using a modified version of the DCC 18 procedure. Three grams (in place of 2 grams) of cleaner (two pumps from supplied bottle) was dosed onto sponge. Each dish was cleaned for 10 second. Foaming level was evaluated by observational analysis based on using sponge method. Tester counted the number of plates until sponge was not able to show any bubbles or forming when tester pressed gently in the center of the sponge with the thumb after washing.

As a result, average number of plates was used to show the cleaning efficacy (longer foaming stability) from each cleaner. Each cleaner was tested three times to measure the efficacy (foaming level).

Trial Results:

Cleaner # of plates AVG # of plates
Dawn Dish Soap 12 11.67
8
15
GMA Dish Soap 4 5
3
8

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.

Conclusion:

The foaming longevity of the GMA Dish Soap is about half that of the Dawn Dish Soap.
