Conclusions:
The Surface Tension of PG-RAW-0004 has been determined to be 56.5 mN/m at 20°C according to OECD TG 115 (Surface Tension of Aqueous Solutions) using the ring method in compliance with GLP. According to EU method A.5, the substance is considered to be surface active because the value is less than 60 mN/m.

Executive summary:

The Surface Tension of PG-RAW-0004 has been determined to be 56.5 mN/m at  20°C according to OECD TG 115 (Surface Tension of Aqueous Solutions) using  the ring method in compliance with GLP. According to EU method A.5, the substance is considered to be surface active because the value is less than 60 mN/m.
