The invention discloses a stable oil-carrying
amino acid surfactant composition and a preparation method thereof, the composition can improve the stability of an oil-containing
personal care product, can construct a stable
liquid crystal structure, and can enhance the
system adaptability and anti-interference capability through the cooperation of a plurality of
amino acid surfactants, so that the stability of the oil-containing
personal care product is improved. A stable and fine
emulsion structure can still be formed under severe storage conditions, so that the
grease is uniformly dispersed and has high emulsifying performance,
grease molecules are wrapped by a
liquid crystal structure, and
grease distribution and release can be optimized by matching with different fatty acids; according to the present invention, the inorganic salt-free or extremely low inorganic salt design is adopted, the low-
irritation amino acid surfactant is adopted as the main material, the inorganic salt-free or extremely low inorganic
salt content is controlled, the
environmental protection problem caused by the
desalination process is avoided, the application range of the formula is expanded, and the formula is flexible and has wide adaptability.
