ANALYTICAL SECTION
PERFLUORINATED COMPOUNDS - PFC
Analytical Method: in-house method developed by BuzziLab (ref. to UNI
CEN TS 15968)
Brief description of the method:
A weighted amount of sample is dissolved in organic solvent; analysis is
performed by GC-MSMS (for PFC telomers) and LC-MSMS (for other
PFCs)
Limit of Detection: 0,001mg/kg
Limit of Quantification (Detox MRSL): 0.01mg/kg

APEOS / CHLOROPHENOLS / PHTHALATES
Test Method: in-house method (developed by Buzzi Lab) was used by high-
resolution mass spectrometry/time-of-flight liquid chromatography (LC-QTOF
equipment).
Brief description of test method: a weighted sample of dye is dissolved in organic
solvent and directly analized by LC-QTOF.
This equipment permit the quantitative analysis of APEOS, Chlorophenols and
Phthalates in a single injection, using high-resolution mass spectrometry (exact
masses) with also low-limit of detection.
Limit of Detection: APEOS and Chlorophenols: 0.01mg/kg – Phthalates: 0.1mg/kg
Limit of Quantification (MRSL): APEOS: 1mg/kg – Chlorophenols: 0.05mg/kg –
Phthalates: 10mg/kg

On the total of 68 samples:
• Only one sample (classified as non-slip agent) is
free of contamination
• frequent contamination is due to PFC Telomer
(FTOH 4:2 and FTOH 6:2 - 30.9%) followed by
APEOS (19.1%) and Phthalates (14,4%);
• Contamination by Chlorophenols regarded only 3
sample (4.4%).

CONCLUSIONS
Only one sample (classified as non-slip agent) is free of
contamination
frequent contamination is due to PFC Telomer (FTOH 4:2 and FTOH
6:2 - 30.9%) followed by APEOS (19.1%) and Phthalates (14,4%);
Contamination by Chlorophenols regarded only 3 sample (4.4%).
Contamination due to PFC, Chlorophenols and APEOS is higher
than Detox MRSL limits, while Phthalate contamination is
generally lower than Detox MRSL limit (except in two cases)

ACTION PLAN
This is the first analytical screening on chemical auxiliaries for spinning
and weaving: successive steps will involve:
1- new screening on the same samples provided by same suppliers to
verify presence/abscence of contaminations in new batches;
2- potential screening (chemical analysis) on same kind of samples if
available from different suppliers;
3- possible extentions of chemical analysis to other priority groups of
Detox MRSL
