一、ISO11930-2012 corrosion challenge test overview

1、Used to evaluate the preservative system in cosmetics;

2、this standard does not require ISO 29621 in the requirements of microbiological low-risk products for preservative challenge test; 

3、Product type: mainly for water-soluble and water-soluble cosmetic formulations product design;

三、ISO 11930-2012 Neutralizer for preservative challenge test

Currently there are the following two cases:

1、the verification test of the effectiveness of the neutralizer, the customer to provide the neutralizer formula, the neutralizer verification, verification of qualified for ISO 11930-2012 anticorrosion challenge test; 

2、 do not carry out the neutralizer verification test, but need to provide customers with neutralizer formulations, the test process will be carried out in the neutralization step, but will not verify the effectiveness of the neutralizer; for details, call the consulting hotline: 13524733472

四、used for preservatives challenge test microbial species

Staphylococcus aureus (with neutralizer), Pseudomonas aeruginosa (with neutralizer), Escherichia coli (with neutralizer), Candida albicans (with neutralizer), Aspergillus niger (with neutralizer).
