Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data
Link to relevant study record(s)
- Endpoint:
- explosive properties of explosives
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties
- Endpoint:
- explosive properties of explosives
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.14 (Explosive properties)
- Deviations:
- yes
- Remarks:
- Insufficient material was available to conduct 6 tests as specified in the A.14 procedure.
- Principles of method if other than guideline:
- Three tests were performed using the 2 mm orifice plate. It was reasoned that if negative results were obtained using the smaller vent orifice it would be reasonable to conclude that similar results would be achieved using the larger 6 mm orifice.
- GLP compliance:
- yes
- Parameter:
- other: Explosive (not specified)
- Remarks on result:
- negative (not further specified)
- Remarks:
- Glycolic acid 70% solution was not found to be sensitive to thermal or impact stimuli.
- Interpretation of results:
- non explosive
- Conclusions:
- Glycolic acid 70% solution was not found to be sensitive to thermal or impact stimuli.
- Executive summary:
Glycolic acid 70% solution was not found to be sensitive to thermal or impact stimuli.
- Endpoint:
- explosive properties of explosives
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.14 (Explosive properties)
- Deviations:
- no
- GLP compliance:
- yes
- Parameter:
- other: Explosive (not specified)
- Remarks on result:
- negative (not further specified)
- Remarks:
- Glycolic acid >99% was not sensitive to impact stimuli, friction, or heating under confinement.
- Interpretation of results:
- non explosive
- Conclusions:
- The solid form of glycolic acid (glycolic acid >99%) was not sensitive to impact stimuli, friction, or heating under confinement.
- Executive summary:
The explosivity of the solid form of glycolic acid (glycolic acid >99%) was investigated according to EC method A.14. The solid form of glycolic acid (glycolic acid) was not sensitive to impact stimuli, friction, or heating under confinement.

No alert in chemical structure.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
The explosivity of glycolic acid 70% solution and the solid form of glycolic acid (glycolic acid >99%) were both investigated according to EU Method A.14. Glycolic acid 70% solution was not found to be sensitive to thermal or impact stimuli. The solid form of glycolic acid (glycolic acid >99%) was not sensitive to impact stimuli, friction, or heating under confinement.
Justification for classification or non-classification
Based on the study results, glycolic acid was not found to be sensitive to thermal, impact or friction stimuli.
The A14 test was relevant according to previous Directive 67/548/EEC "DSD" criteria; based on these, glycolic acid, as solid or solution, was considered NOT to be explosive and did not warrant any classification.
According to Regulation (EC) No 1272/2008 "CLP", in the stepwise approach, glycolic acid fulfills the exemption criteria regarding the lack of chemical group associated with explosive properties in the structure. Therefore no further testing is required. Both >99% grade and 70% solution do NOT warrant any classification for explosivity.
