Trial Number 2

Trial Purpose:

To evaluate the effectiveness of E-Mop with 5 g salt and Febreze Fabric Free Nature on the elimination of unwanted odors.

Date Run:

06/19/2019

Experiment Procedure:

A total of seven clean glass bottles were each filled with ten milliliters of whole milk. Six of these bottles were treated by formulations and the remaining one bottle was used as a control. All bottles were capped and stored in a room for six days at room temperature (68 °F). After the six-day spoiling period, the bottles were opened and a panel of five observed for signs of spoiling odor, according to the rating system (see below). Three bottles were reserved for each formulation, and two sprays of the respective formulations were sprayed into each bottle. After swirling the contaminants in the bottle ensuring a mixture, the odor panel graded each bottle with their ratings recorded. This process continued by introducing two sprays into each bottle of its respective formulation and rating until six spays were reached. The bottles containing the spoiled milk were stored once again at room temperature and sat overnight. All testing bottles were rated the next day with no treatment, and then an additional two sprays were added before final ratings. E-Mop with 5 g salt was used at a temperature of 71 °F and a pH of 8, and Febreze Fabric Free Nature was used at a temperature of 74.7 °F and a pH of 6.

The following rating system was used to assess the malodor of the spoiled milk:    1 = No Malodor       5 = High Malodor

Trial Results:

Overnight, E-Mop with 5 g salt and Febreze Fabric Free Nature increased the malodor rating. Overall, after treating each bottle with formulation with 8 sprays, E-Mop with 5 g salt slightly changed the malodor rating and Febreze Fabric Free Nature Formulation did not significantly change the malodor rating compared to the original malodor rating of each bottle.

Success Rating:

A cleanliness study, addressing only various analytical techniques.

Conclusion:

E-Mop with 5 g salt was observed to be slightly more effective than and the comparative formulation, Febreze Fabric Free Nature Formulation, in eliminating the malodor of spoiled milk. Febreze Fabric Free Nature Formulation was observed to not significantly reduce the original malodor of the spoiled milk. Overall, E-mop with 5 g salt reduced the original rating by 0.47, and Febreze Fabric Free Nature Formulation reduced the original rating by 0.03.
