The results of the CSM test showed a lower degree of staining after exposure to DPD formula compared to other mild detergents. The 100-CIM value is proportionately related to the degree of SC damage and subsequent staining. Therefore, DPD formula was shown to cause the lowest level of SC damage compared to other mild laundry detergents. In contrast, Product 11 was associated with the greatest amount of SC damage. With the exception of Product 4, these differences compared to DPD formula were found to be statistically signi cant.
As Figure 4 shows, the EpiDermTM Skin Model released a lower level of cytokine IL-1α after exposure to DPD formula when compared to the other mild detergents. Additionally, there was a marked difference between the amounts of cytokine IL-1α released after exposure to DPD formula compared to Product 11. With the exceptions of Products 1, 2, 4, and 5, the difference between the samples were found to be statistically significant. Therefore, DPD formula was shown to induce a lower
