Hair-care and skin-care composition comprising cationic surfactant

The invention discloses a hair-care and skin-care composition comprising a cationic surfactant. The hair-care and skin-care composition consisting of the cationic surfactant comprises the following components: 0.01 to 5 parts of long-chain PEG group hydrophobic modified compound; B) 1 to 8 parts of higher aliphatic alcohol; and C) 0.1 to 5 parts of cationic surfactant with a formula N+R1R2R3R4 orR1CONHC3H6NR2R3, wherein in the compound C), R1, R2, R3 and R4 are independently alkyl or benzyl with carbon atom number being 1 to 30. The hair-care and skin-care composition consisting of the cationic surfactant, which is provided by the invention, has high economic property, proper viscosity, good use feeling and low-temperature stability; the hair-care and skin-care composition can effectivelythicken the formula of cationic surface active cream under the condition of reducing the use amount of higher aliphatic alcohol or not using macromolecules such as hydroxyethyl cellulose, and can relieve the formula layering
