Ammonium Chloride Average pH-adjuster-stabiliser No known benefits Ammonium Chloride at a glance Used to increase cosmetic products’ viscosity Also used commercially as a dough strengthener Can cause skin sensitivity White crystalline solid in its raw form Ammonium Chloride description Ammonium chloride is an inorganic salt (a type of salt missing carbon and hydrogen bonds) that is used in cosmetics primarily to boost a product’s texture, particularly its viscosity. In commercial food preparations, ammonium chloride is used as a dough strengthener. The European Organization for Economic Cooperation and Development (OECD) High Production Volume (HPV) chemical program has determined, based upon research presented, that ammonium chloride is not an allergen. However, it did note some instances of skin sensitization, meaning that if you have a known sensitivity to ammonium chloride, it should be avoided. In its raw form, ammonium chloride is a white crystalline solid. Amounts between 15–20% are standard when aluminum chloride is used in deodorants or anti-perspirants.
