Storage stability and reactivity towards container material
Administrative data
Link to relevant study record(s)
- Endpoint:
- storage stability and reactivity towards container material
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: GLP Compliance
- Reason / purpose for cross-reference:
- reference to same study
- Principles of method if other than guideline:
- Evaluations of the percent of glycolic acid and methyl glycolate before and after 14 days at 54°C were conducted. The packaging material (HDPE) was also examined for signs of reactivity with the test substance.
- GLP compliance:
- yes
- Type of method:
- accelerated testing
- Results:
- Glycolic acid showed no signs of reactivity towards HDPE packaging.
- Storage stability / reactivity towards container material:
- other: No reactivity towards HDPE packaging.
- Conclusions:
- Glycolic acid showed no signs of reactivity towards HDPE packaging.
- Executive summary:
Glycolic acid showed no signs of reactivity towards HDPE packaging.

| After 14 days at 54°C | 66.2 | 67.6 | 66.9 |
Description of key information
Glycolic acid showed no signs of reactivity towards HDPE packaging.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
