Test material
- Reference substance name:
- 1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-coco acyl derivs., hydroxides, inner salts
- EC Number:
- 263-058-8

- Molecular formula:
- C19H38N2O3
- IUPAC Name:
- {[3-(Dodecanoylamino)propyl](dimethyl)ammonio}acetate
- Test material form:
- liquid
Constituent 1
- Specific details on test material used for the study:
- Physical state: liquid, aqueous solution
- Analytical purity: 30% a.i.
- Composition of test material, percentage of components: 30 % active (C8-18 with majority in C12-14), 7 % sodium chloride, 63 % water
- Lot/batch No.: 26R-259.
The members of the alkyl betaines category are amphoteric surfactants containing a quaternary ammonium ion and a carboxylic structure. They are referred to as inner salts due to their zwitterionic character. They are all manufactured from natural materials such as vegetable oils and can vary in chain length from C8 to C18. They are generally marketed as aqueous solutions (20 - 40 %).
Because of the structural and functional similarities and comparable physico-chemical properties these inner salts and sodium salts, a similar ecotoxicological and toxicological profile can be expected.
The Cosmetic Ingredient Review Expert Panel reviewed the product use, formulation and safety data of eleven alkyl betaines, as used in cosmetics. (Final report issued 2014-04-04)
The Panel concluded that the common core chemical structure, similar functions and concentrations in cosmetics, and the predicted physicochemical properties enabled grouping these ingredients and reading across the available toxicological data to support the safety assessment of each individual compound in the entire group.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Cocoalkyldimethylbetaine has a similar structure to lauryl betaine.This is considered to be a good surrogate substance for the lauryl betaine being registered.
Further animal testing cannot be justified. - Executive summary:
