Abstract: A cleansing composition includes at least two visually distinct phase layers that include a first visually distinct phase layer including at least one amino-acid derived cationic surfactant, and at least one inorganic salt, and a second visually distinct phase layer including at least one plant-derived alkane or plant-derived alkylether. The at least one cationic surfactant is an amino acid based cationic surfactant that may be selected from a derivative ethyl lauroyl arginate or a salt thereof, and ethyl cocoyl arginate or a salt thereof (PCA ethyl cocoyl arginate). The first visually distinct phase layer may be present at about 50% to about 95% and the second visually distinct phase layer may be present at about 5% to about 50%, by weight, based on the total weight of the cleansing composition.

Abstract: A cleansing composition includes at least three visually distinct phase layers. The first visually distinct phase layer includes at least one cosmetic solvent and has a Hilderbrand solubility parameter δ value that is greater than 15 cal.1/3. cm−2/3 and includes at least one cationic surfactant and at least one inorganic salt. The second visually distinct phase layer includes at least one cosmetic solvent having a Hilderbrand solubility parameter δ value less than 7.5 cal.1/3. cm−2/3. And the third visually distinct phase layer includes at least one cosmetic solvent having a Hilderbrand solubility parameter δ value that is between 8 and 10 cal.1/3. cm−2/3.
