Safety Profile
No dedicated CIR or SCCS safety assessments exist for this ingredient. While the FDA lists 'Rosin, diethylene glycol ester' as an indirect food additive, its component Diethylene Glycol (DEG) is a known toxic contaminant, necessitating strict control. Paula's Choice suggests a likelihood of irritation, particularly for sensitive skin types or in combination with other problematic ingredients.
