A personal care composition, comprising:
- an emulsifying system comprising 0.1-2 weight % of cationic surfactants and 2-5 weight % of nonionic surfactants;
- fatty alcohols comprising cetyl alcohol, stearyl alcohol, or combinations thereof, wherein the cetyl alcohol and the stearyl alcohol are present in an amount of greater than or equal to 5 weight %, based on a total weight of the personal care composition;
- 0.1-5 weight % of one or more emollients;
- and
- 1-6 weight % of one or more humectants;
- all based on a total weight of the personal care composition;
- wherein the nonionic surfactants comprises cetearyl alcohol, ceteareth-20, or combinations thereof, and wherein cetearyl alcohol and/or ceteareth-20 are present in an amount of 3 weight % to 5 weight %, based on a total weight of the personal care composition;
- wherein the personal care composition has an acidic pH of from 4.2 to 4.8;
- and
- wherein the personal care composition is selected from the group consisting of;
- (A) a formulation comprising 0.03 weight % of Dipalmitoylethel Dimonium Chloride, 4.00 weight % of Cetearyl Alcohol/Ceteareth-20, 3.00 weight % of Stearyl Alcohol, 3.50 weight % of Cetyl Alcohol, and 1.50 weight % of Isopropyl Palmitate, based on the total weight of the personal care composition;
- (B) a formulation comprising 0.50 weight % of Dipalmitoylethyl Dimonium Chloride, 4.00 weight % of Cetearyl Alcohol/Ceteareth-20 1.50 weight % of Stearyl Alcohol, 3.50 weight % of Cetyl Alcohol, and 1.50 weight % of Isopropyl Palmitate, based on the total weight of the personal care composition;
- and
- (C) a formulation comprising 0.05 weight % of Dipalmitoylethyl Dimonium Chloride, 4.00 weight % of Cetearyl Alcohol/Ceteareth-20, 3.00 weight % of Stearyl Alcohol, 3.50 weight % of Cetyl Alcohol, and 4.00 weight % of Isopropyl Palmitate, based on the total weight of the personal care composition.
