Description - 
Natural Moisturizing Factor (NMF), Hydration Booster & Skin Conditioning Active
This Reaqua BT99 is a highly purified form of Betaine, a naturally occurring osmolyte derived from biological sources and widely recognized as a component of the skin’s Natural Moisturizing Factor (NMF).
It helps maintain optimal moisture balance within skin and hair by regulating water retention at the cellular level. Known for its excellent moisturizing performance and irritation-reducing properties, Betain enhances formulation mildness while improving skin feel and hydration.
This multifunctional ingredient supports smoother skin texture, improved barrier comfort, and enhanced foam performance in cleansing systems.

How It Works - 
Betaine functions as an osmolyte, meaning it helps skin cells regulate water balance. Instead of simply attracting moisture like traditional humectants, it stabilizes hydration levels inside the skin, preventing dehydration and irritation.
In surfactant systems, it reduces harshness by improving skin compatibility, making cleansers feel gentler and more conditioning.
