1 A behenyl (C22) cationic quaternary ammonium salt conditioning emulsifier. 2 The active matter of the quaternary ammonium salt accounts for about 50%, which brings a significant thickness to the emulsified formula. 3 As a C22 methyl sulfate quaternary ammonium salt, it is more hydrophobic in nature. 4 It is easier to deposit positive cationic terminals and lipids on the hair than the conventional C18 quaternary ammonium salt, thereby providing better conditioning performance. At the same time, the hydrophobicity and deposition behavior of BTMS 50 make the product have excellent dry hair combability, and it does not need to be deposited with other polymer quaternary ammonium compounds, but also has excellent conditioning properties, and the formulation is convenient for application. 5 As a basic emulsifier and conditioner BTMS 50 has a wide range of applications in hair care and skin care.
