Result : not irritating<br />
Classification : not irritating<br />
Method : other: revised FHSA procedure proposed by FDA (US)<br />
Year : <strong>19</strong>75<br />
GLP : no<br />
Test substance : other TS: sodium carbonate<br />
Method : METHOD FOLLOWED: Probably comparable to OECD guideline 404, as<br />
FHSA procedure proposed by FDA was used. However, description was too<br />
short to make a full comparison.<br />
DEVIATIONS FROM<br />
OECD GUIDELINE 404: Test substance was suspended in water in stead<br />
of being moistened with water; scores done at 4, 24 and 48h, instead of 1,<br />
24, 48 and 72h; most subjects were reexamined after one month; intact skin<br />
and abraded skin was used instead of only intact skin; reporting less<br />
elaborate than guideline demands.<br />
GLP: No<br />
