Overview
Cocamidopropyl betaine is a cleanser that is usually blended with other cleansers to improve foam and make beard hair feel softer and easier to comb after rinsing.
Use it only in a complete water-based wash, never as an addition to beard oil or balm. Follow the supplier's amount and mixing directions, check the finished product's pH (acidity level) and thickness, use a suitable preservative, and test a small batch for rinse feel and user comfort.
