Steartrimonium Chloride Quick-Dry Base 70 CAS NO 112-03-8
Let me introduce a practical raw material - STEARTRIMONIUM CHLORIDE. The core ingredient is 70% active STEARTRIMONIUM CHLORIDE, which is a soft solid with a white color. It is based on ethanol and has a fast dissolution rate, making it easy to process even in low temperature environments. The formula stability is particularly reliable. Whether the pH value is between 6.0 and 8.0, or when heated for a short period of time during the mixing process, it can work stably, making it both convenient and worry free to use.
Functional Role in Formulations
The logic behind the effectiveness of this ingredient in the formula is very clear. The positively charged quaternary ammonium groups in the molecule act as magnetic anchor points, firmly adsorbing onto negatively charged surfaces such as hair and clay, forming a smooth anti-static film; The long alkyl chains act as hydrophobic shields, enhancing the hydrophobicity of the treated surface. In addition to the characteristics of ethanol base, it can speed up drying, and is very suitable for anhydrous formulas or products that need rapid drying, such as wash free spray and quick drying hair film. When used alongside cationic polymers such as
Ammonium acrylate copolymer, it can enhance film formation and surface adherence.
Application and Suitability
Its application scenarios are also quite extensive. In the field of cosmetics, when making solvent based hair conditioners or styling products that pursue non stick and low static electricity (such as hair wax and hair gel), adding it can make hair smooth and easy to manage. Moreover, due to its high concentration, only a small amount needs to be added to take effect, which saves costs and is convenient to mix.
Usage and Handling Notes
It is very easy to operate and use, without the need for pre heating. It can be directly dispersed into the system, which can simplify many formula steps. In personal care products, typically 1% to 3% is added; However, there is one thing to note: do not use it with strong anionic surfactants, otherwise it may fail or precipitate. When stored normally, it should be sealed and kept away from heat sources and oxidants to ensure its stability and longer storage time.
