Taffix is formulated with ingredients designated by the US Food and Drug Administration (FDA) as Generally Recognized as Safe (GRAS) and approved as inactive ingredients for nasal use. These ingredients are commonly used as excipients in pharmaceutical preparations, particularly in eye preparations and nasal sprays.

Taffix was developed based on established scientific principles and knowledge of the impact of pH on viral survival, combined with precedence for use of gel-based muco-adhesives in products intended for intranasal administration to coat the nasal mucosa and block passage of foreign bodies across the mucosal membrane.^3,5
