About IMPATIENS BALSAMINA FLOWER EXTRACT
Extracted from the flowers of Garden Balsam, this ingredient combines astringent properties with a fragrance function, but its lawsone content — a known sensitizer — and fragrance allergen potential raise important safety considerations. Careful concentration control is required.
Detailed Analysis
Impatiens balsamina L. (Balsaminaceae) flowers contain lawsone (2-hydroxy-1,4-naphthoquinone), kaempferol glycosides, and aromatic volatile compounds responsible for the extract's simultaneous astringent and fragrance functions. Lawsone is a documented contact sensitizer; under EU Regulation (EC) No 1223/2009, its use in oxidative hair dye products is restricted, and its presence in any leave-on or rinse-off cosmetic necessitates a comprehensive sensitization risk assessment. The dual astringent/fragrance role of this extract means both the lawsone content and the full fragrance allergen profile must be analytically characterized before cosmetic use.
