ABSTRACT:
A process for the non-aqueous neutralization of N-Acyl sarcosines. N-Acyl sarcosines are neutralized with anhydrous hydroxide or with hydroxide with low water content, ideally less than 20% water, using high shear. The process eliminates numerous stages previously required on route to a 100% active product. In addition, 30% solutions can be produced by the instant process, with the advantage of avoiding pH ranges at which gel phases or liquid crystals form.
