Detergent Mildness Index: Measuring impact on skin

The Detergent Mildness Index (DMI) uses a series of three tests commonly used in the skin-care industry to measure product mildness. all® free clear was shown to be the mildest* sensitive-skin laundry detergent.

* Mildest amongst leading Sensitive Skin laundry detergents. Milder using a combination of 3 tests: zein, cytokine, and corneosurfametry. Patch test results were the same across all sensitive skin detergents tested.

Zein Test: Measuring protein damage

The Zein Test indicates levels of potential irritancy by analyzing protein damage in the outer layer of skin. This test shows all® free clear maintains skin protein better than other sensitive-skin detergents.

Measuring Protein damage

Corneosurfametry Test: Measuring protein and lipid degradation

The Corneosurfametry Test assesses the degradation of stratum corneum proteins and lipids using top layers of skin that are soaked in detergent, and then placed in a dye to highlight damage. More staining reflects more cell damage.

Here you see that all® free clear is even similar to the control: water.

Cytokine Test: Measuring inflammatory response

The Cytokine Test goes deeper to measure inflammatory response due to detergent exposure by testing levels of keratinocyte-derived IL-1⍺.

all® free clear shows minimal response, with skin layers remaining clearly defined.
