Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Qualifier:
according to guideline
Guideline:
other: Croda Inc Test Method, Title: Percent solids / moisture (4g 105 degrees C 2 hrs).
Version / remarks:
Croda Inc Test Method No.: FU2906B0, Revision No.: 2, Date: 05/22/2012.
Deviations:
not applicable
Principles of method if other than guideline:
- PRINCIPLE OF TEST:
To determine the ratio of solids / nonvolatile content of a given material.

- PROCEDURE:
1. Weigh accurately a clean, dry, empty aluminium weighing pan. Record weight to 0.1 mg.
2. Accurately weigh (to 0.1 mg), 4g of sample in to aluminium pan. Record weight to 0.1 mg.
3. Place aluminium pan in to preheated Forced Draft Oven at 105°C for two (2) hours.
4. Cool to room temperature in a dessicator.
5. Reweigh the aluminium pan and sample. Record weight to 0.1 mg.
6. Run analysis in duplicate.

Conclusions:
The water solubility of 1-Propanaminium, N-(3-aminopropyl)-2-hydroxy-N,N-dimethyl-3-sulfo-, N-coco acyl derivs., hydroxides, inner salt was determined to be be at least 52 % by performing Loss on Drying (LOD) method on the commerical product Crodateric CAS-50-LQ-(MH).
Executive summary:

A Loss on Drying (LOD) method was used to determine the percent moisture content of the commerical product Crodateric CAS-50-LQ-(MH) which contains the registered substance.

1-Propanaminium, N-(3-aminopropyl)-2-hydroxy-N,N-dimethyl-3-sulfo-, N-coco acyl derivs., hydroxides, inner salt was determined to be highly soluble in water with at least 52 % water solubility.
