Lawsone, a natural component in the hair dye preparations of Lawsonia inermis, has been
examined by SCCNFP which in its latest opinion on Lawsone (SCCNFP/0798/04), adopted on
16 February 2004, stated that ‘ Lawsone has genotoxicity/mutagenicity potential in vitro and in
vivo and that therefore no safe threshold for Lawsone can be established.’
2. TERMS OF REFERENCE
1. Does the Scientific Committee on Consumer Products (SCCP) consider Lawsonia inermis
safe for use as a hair dye taken into account the scientific data provided?
2. Does the SCCP recommend any restrictions with regard to the use of Lawsonia inermis in
any hair dye formulations?
questo è il campione esaminato :
3.1.5. Impurities / accompanying contaminants
Sample No. 1271 from LOGOCOS
Pesticides
Investigation of contamination of Sample No. 1271 for 30 commonly used pesticides revealed
absence of these pesticides in the sample (detection limits 0.01 -3 ppm depending upon the
compound)
Metals
Lead 1.04 ppm, Cadmium 0.11 ppm, Mercury 0.03 ppm, Arsenic 0.47 ppm, Copper 7.87 ppm,
Chromium 9.4 ppm and Nickel 8.06 ppm, Iron 4915 ppm
In conclusion, it can be stated that under the experimental conditions reported, the test item did not induce gene mutations by base pair changes or frame shifts in the genome of the bacterial
strains used in the presence and absence of S9-mix. Thus, Henna rot (batch 830.72) was shownto be non-mutagenic in this Salmonella typhimurium test.
Ref.: 5 (subm. II)
In conclusion, Henna Rot (batch 830.72) is not mutagenic in the HPRT gene mutation test with
V79 cells under the test conditions used.
Ref.: 7 (subm. II)
Essendo molto lungo passo all conclusioni finali
4. CONCLUSION
The SCCP is of the opinion that the information submitted is insufficient to assess the safe use of
the substance as a hair dye.
To exclude a clastogenic potential of Henna Rot (Lawsonia inermis), additional testing with
batch 1271 is required. An additional in vitro chromosome aberration test or (preferentially) an
in vitro micronucleus test should be performed. In case of a positive result, appropriate in vivo
genotoxicity testing has to be considered.
The traditional and current expanding use of Henna Rot (Lawsonia inermis) as a body-paint has not been assessed.
