Applicant's summary and conclusion
- Conclusions:
- Using the Static Technique, the vapour pressure of Phytosphingosine at 20°C was determined to be (representative for Phytosphingosine Sulfate (PSS):
0.20 ± 0.03 Pa = (1.5 ± 0.2)x10^-3 mm Hg - Executive summary:
The determination of the vapour pressure was performed in accordance with the following guidelines: OECD guidelines for Testing chemicals, Guideline No.104: "Vapour pressure curve", July 27, 1995.
Using the Static Technique, the vapour pressure of Phytosphingosine (representative for Phytosphingosine Sulfate (PSS)) at 20°C was determined to be: 0.20 ± 0.03 Pa = (1.5 ± 0.2)x10^-3 mm Hg.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
