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.
Claims20
A cleansing composition comprising:
- at least three visually distinct phase layers that include a first visually distinct phase layer comprising at least one cosmetic solvent having a Hildebrand solubility parameter δ value that is greater than 15 cal1/2cm−3/2, a second visually distinct phase layer comprising at least one cosmetic solvent having a Hildebrand solubility parameter δ value less than 7.5 cal1/2cm−3/2, and a third visually distinct phase layer comprising at least one cosmetic solvent having a Hildebrand solubility parameter δ value that is between 8 and 10 cal1/2cm−3/2.
A cleansing composition comprising:
- (a) at least one phase layer that includes at least one amino acid based cationic surfactant selected from the group consisting of a derivative ethyl lauroyl arginate or a salt thereof, and ethyl cocoyl arginate or a salt thereof;
- at least one inorganic salt selected from the group consisting of sea salt, sodium chloride, magnesium chloride, calcium chloride, potassium chloride, magnesium sulfate, magnesium carbonate, calcium carbonate, zinc pyrrolidone carboxylic acid, and combinations thereof;
- and at least one cosmetically acceptable solvent with a Hildebrand solubility parameter δ value greater than 15 cal1/2cm−3/2, the solvent selected from water, and water based solvents, such phase layer present in an amount, by weight of the cleansing composition in a range from about 20% to about 80%;
- (b) at least one phase layer present in an amount, by weight of the cleansing composition in a range from about 5% to about 50%, and comprising at least one cosmetically acceptable solvent with a Hildebrand solubility parameter δ value less than 7.5 cal1/2cm−3/2, the solvent comprising oil selected from the group consisting of C15-19 alkane, undecane, tridecane, isopropyl palmitate, Isododecane, and combinations thereof;
- (c) at least one phase layer present in an amount, by weight of the cleansing composition in a range from about 5% to about 50%, and comprising at least one cosmetically acceptable solvent with a Hildebrand solubility parameter δ value between 8 and 10 cal1/2cm−3/2, the so solvent comprising triethyl citrate all amounts by weight, based on the total weight of the cleansing composition.
A method for forming a multi-phase cleansing composition, the method comprising:
- forming a first phase comprising at least one cosmetic solvent having a Hildebrand solubility parameter δ value that is greater than 15 cal1/2cm−3/2 and comprising at least one cationic surfactant and at least one inorganic salt;
- forming a second phase layer comprising at least one cosmetic solvent having a Hildebrand solubility parameter δ value less than 7.5 cal1/2cm−3/2;
- forming a third phase layer comprising at least one cosmetic solvent having a Hildebrand solubility parameter δ value that is between 8 and 10 cal1/2cm−3/2;
- combining the first second and third phase layers to provide a multi-phase cleansing composition wherein each of the phase layers are visually distinct, and wherein, when agitated, the cleansing composition forms a milky single phase which separates after agitation into three or more visibly distinct phases in a maximum period of 24 hours.
