Trial Purpose:
To evaluate supplied products for odor elimination
Date Run:
11/25/2013Experiment Procedure:
Clean 200 ml glass bottles were filled with 1 ml of whole milk. The bottles were capped and stored at room temperature for three days. At the end of the three days, the bottles were opened and observed for signs of spoiling odor.
The Toucan Eco product was run through two cycles using 2.8 grams of salt and 1330 grams of water at room temperature. Resulting free chlorine level was recorded. Three bottles were opened and treated with four sprays of one of the supplied cleaning products. Bottles were capped and swirled to mix the cleaner with the milk.
A panel was initialized to the various odors. An untreated bottle, a bottle with spoiled milk, a bottle with Toucan Eco solution, a bottle with Formula 409, Febreze and a bottle with water only were presented to the panelist. The exposure was to set a bench mark for each possible odor contributor.
The treated bottles were then presented uncapped to one member of the odor panel. The panelist was asked to describe odor and rank the level of intensity of the malodor. Each panelist was subjected to three bottles for each product/milk mixture plus a selection of the initial odor bottles in random odor.
After the panelists observed the odors, bottles were recapped and allowed to set for two days. Bottles were reopened and assessed for odors. Each bottle was subjected to a second round of treatment and one panelist was used to asses malodor levels. A second and third round of treatment and sitting were performed to determine longevity of odor elimination for each product.
ChemistriesEvaluated: Toucan Cleaner (200 ppm); Formula 409 All Purpose Antibacterial; Proctor & Gamble Febreze free-nature; Water:
Trial Results:
After the initial treatment, each of the observers noted that no product eliminated all of the malodor in each test bottle. The Toucan treated bottles had initial success with two bottles with no malodor and the third with low malodor. The Formula 409 treated bottles had a strong odor from the product with some malodor present. The Febreze bottles had moderate amount of malodor present. The control bottles treated with water each had a strong malodor. To ensure enough product was applied to the bottles, a second round of treatment and analysis was conducted within two hours of the initial treatment. The Toucan bottles had no malodor and the distinct smell of product. The Formula 409 was 60:40 split between malodor and product in two of the bottles and a 40:60 malodor to product in the third. The Febreze samples had little malodor present.
| Toucan | Formula 409 | Febreze | Water |
| No malodor, some product | medium/strong malodor | medium malodor | Strong Malodor |
| Low malodor, some product | even split malodor | medium malodor | Strong Malodor |
| No malodor, some product | 40:60 malodor/product | some malodor | Strong Malodor |
Following the two day interval after being treated, the results were slightly different.
| Second round of sprays | |||
| Toucan | Formula 409 | Febreze | Water |
| no malodor, little product | 60:40 malodor, product | little malodor | Strong Malodor |
| no malodor, some product | 40:60 malodor, product | little malodor | Strong Malodor |
| no malodor, only product | 60:40 malodor, product | little malodor | Strong Malodor |
When the treated bottles sat for an additional two days, the malodor came back in the Toucan product with no trace of the product. An even mix of malodor and product was observed with the Formula 409 bottles. The Febreze bottles had a different odor than the original malodor and product. Water still smelled strongly of the malodor.
Sit for 2 days after being treated
| Toucan | Formula 409 | Febreze | Water |
| Strong Malodor | 50:50 malodor, product | different odor | Strong Malodor |
| Strong Malodor | 50:50 malodor, product | different odor | Strong Malodor |
| Strong Malodor | 50:50 malodor, product | different odor | Strong Malodor |
The bottles were then sprayed with the products and analyzed again to determine malodor elimination. The Toucan bottles again had no to little malodor. The Formula 409 bottles were mostly product at an 80:20 split. The Febreze was a more even split with slightly more product odor than the malodor.
Sit for 2 days after initial treatment then sprayed with product
| Toucan | Formula 409 | Febreze | Water |
| No malodor | All product no malodor | Product 50:50 | Strong Malodor |
| Product: malodor 90:10 | All product no malodor | no malodor | Strong Malodor |
| Product: malodor 85:15 | All product no malodor | Mostly product | Strong Malodor |
The bottles were then allowed to sit for another two days to determine long term effect on malodor elimination. As in the other trials, the Toucan bottles reverted back to the malodor with no odor of product present. The Formula 409 smelled more like the product than the malodor. The Febreze remained fairly constant with slightly more product odor than the malodor.
Sit for 2 days after being treated
| Toucan | Formula 409 | Febreze | Water |
| no product all malodor | Mostly product 80:20 | Product 60:40 | Strong Malodor |
| no product all malodor | Mostly product 80:20 | Product 60:40 | Strong Malodor |
| no product all malodor | Some product no malodor | Product 60:40 | Strong Malodor |
Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
Toucan product had good initial control of the malodor but over time, the malodor returned. Formula 409 Antibacterial product also had good initial malodor control and had better long term control. The Febreze had marginal success during initial treatment and maintained a similar level of control over time.
