Conditioning Solution with Steartrimonium Chloride 29% CAS NO 112-03-8
There is a product that is a 29% active aqueous solution of ammonium chloride. Silammonium chloride is a quaternary ammonium surfactant with a long C18 alkyl chain. It appears as a colorless to slightly viscous liquid with high solubility in water, a pH value between 6.0 and 8.0, and stable chemical properties in neutral to weakly alkaline environments. Whether it is for personal care products or industrial applications, it is good at wetting objects and can also have a smooth conditioning effect.
Principle of action
Its working principle is actually not difficult to understand. That long C18 alkyl chain can generate hydrophobic interactions with hair keratin or mineral surfaces, while quaternary ammonium groups can electrostatically bind with negatively charged substances. This dual effect forms a sticky film, making hair easier to comb and smoother, and reducing static electricity. In improved clay or coatings, it can enhance surface activity and help form structurally stable dispersions.
Application in cosmetics
In cosmetic formulas, it is a mild conditioning agent in wash off hair care products that can soften hair, reduce friction, and prevent residue accumulation. As a typical
Cationic Softener used in rinse-off systems, it is suitable for making mild formulas that can be used for sensitive scalp or products that pursue lightweight care effects. In industrial applications, it is used to improve bentonite, making it more compatible with oil and assisting in water treatment processes. It has good compatibility with non-ionic emulsifiers and polymers, and has high flexibility in formulation. And it has similar functions to Sila aluminum chloride, both of which have core conditioning effects, while also having the convenient use of water-based products.
Formula usage
This water-based solution is easy to add to the formula, without high temperature or high-intensity stirring. In wash off hair care products, 0.2% to 1.5% is generally added; In industrial formulas such as clay improvement or surface care, a maximum of 3% can be added. It should be noted that it should not be placed in the same aqueous phase as anionic surfactants, otherwise it may fail or cause delamination.
