Challenges with CLP

AkzoNobel Surface Chemistry | SEPAWA Fulda 2015

Example: The classification for a mixture with 4% product classified as H318 will change from notclassified to eye effect category 1.

Not classified products – amphoterics

The special amphoteric Ampholak 7TX

is more efficient in reducing the eye

irritation score compared to a standard

CAPB (cocoamidopropyl betain).

Total Draize score of Sodium Laureth-2 Sulfate and amphoteric mixtures.Approx. 8% active matter, pH 7

Reducing eye irritation of anionic surfactants

Berol® 260Excellent fatty soil removal in water based cleaning productsespecially when it is combined with performance boosting co-surfactants

Berol® 840Low foaming nonionic surfactant with defoaming properties onprotein foam

Ethylan® 1003Excellent emulsifying and wetting propertiesLow foaming hydrophobic surfactant for cold degreasingVery good aquatic toxicity

The classification has been changed from H318 to H319

A.I.S.E. / CESIO in vitro program

ERASM EDI project to address concentration related effects (SCL)

with pure and diluted surfactants for eye damage/irritation

Main project objectives:– Develop an in vitro test strategy to set specific concentration

limits for surfactants.– Develop a method to allow classification as Category 2 based

on in vitro data.

On-going activities


Summary

10

To support customers in creating new solutions to meet thestricter regulations demands AkzoNobel Surface Chemistryoffers surfactants with• reduced or no classification• superior cleaning performance at low concentrations

On-going activities to understand better the relation betweenin-vitro and in-vivo eye test results for CLP classification ofsurfactants
