A study of the sensitization rate to cocamidopropyl betaine in patients patch tested in a university hospital of Beijing
The prevalence of sensitization to cocamidopropyl betaine (CAPB) in China has not been reported and the need for further research into this issue is still unclear.
Study of the composition of 140 shampoos: similarities and differences depending on the sales channel used
Overall, the most common active ingredients were olamines, zinc pyrithione, azoles, selenium disulphide, and plant extracts in shampoos sold in pharmacies.
Synthetic and Bio-Derived Surfactants Versus Microbial Biosurfactants in the Cosmetic Industry: An Overview
It would be interesting for cosmetic, personal care and pharmaceutical industries to consider microbial biosurfactants as a group apart from surfactant, needing specific regulations, as they are less toxic and more biocompatible than chemical surfactants having formulations that are more biOCompatible and greener.
Surfactantes derivados do fruto de coco (Cocos nucifera L. ) e sensibilidade cutânea
O levantamento avaliou 38 documentos e demonstrou that os produtos descritos sao pouco irritativos para a pele, sendo considerados seguros para o uso humano, no entanto, relatos de sensibilidade tardia nao sao raros e tem aumentado em numero.

Occupational allergic contact dermatitis from 3‐dimethylaminopropylamine in shampoos
A non-atopic woman, born in 1958, who had worked as an assistant nurse since 1984, developed dermatitis on both hands in 1992, and left her job because of the hand dermatitis, and started to study.
Pure cocamidopropylbetaine is not the allergen in patients with positive reactions to commercial cocamidopropylbetaine
Allergic contact dermatitis from antimycotic imidazoles is uncommon when compared to their widespread use, and the high concentration of tioconazole, the presence of undecylenic acid and of ethyl acetate in the vehicle, as well as its application to periungual folds are all factors favouring sensitization.

3‐Dimethylaminopropylamine: a key substance in contact allergy to cocamidopropylbetaine?
The results suggest that the DMPA present at various levels as an impurity in the commercial product is responsible for cocamidopropylbetaine allergy.
Contact allergy to impurities in surfactants: amount, chemical structure and carrier effect in reactions to 3‐dimethylaminopropylamine
The study showed that DMPA remains as a quantitatively detectable impurity in all tensioactives employing it in their synthesis, and that no sensitizing action can be attributed to the functional groups present in alkylamidopropylbetaine molecules.
