Hydrophobie
Peroxyde d'hydrogèneLe peroxyde d'hydrogène (H2O2), communément appelé eau oxygénée ou encore perhydrol (appellation industrielle), est un composé chimique liquide et visqueux, aux puissantes propriétés oxydantes (il est aussi réducteur). C'est donc un agent blanchissant efficace qui sert de désinfectant et (à haute concentration) d'oxydant ou monergol dans les fusées spatiales.

| Résumé : |
- Objective : The purpose of this study was to clarify the impact of protein carbonylation on the chemical characteristics of the hair surface focusing on hydrophobicity.
- Methods : First, we examined the validity of methods to evaluate hydrophobicity, one that utilizes the fluorescence of 1-anilinonaphtalene-8-sulfonic acid (1,8-ANS) compared with the contact angles against H2O, of the hair surface chemically modified by alkaline hydrolysis or treated with stearyl ammonium chloride. We measured hairs bleached with H2O2 or treated with acrolein for fluorescence originating from 1,8-ANS, for the contact angle and for changes of functional groups, aldehydes (the degree of carbonylation), NH2, COOH and SH, using fluorescence labelling methods.
- Results : The fluorescence intensity of 1,8-ANS of the hair surface modified chemically correlated well with the contact angles against H2O. The results indicated that 1,8-ANS is suitable for evaluating the hydrophobicity of the hair surface. The hydrophobicity of hairs bleached with H2O2 or carbonylated with acrolein was decreased. In addition, changes of functional groups in hairs carbonylated with acrolein increased as did those of hairs bleached with H2O2.
- Conclusion : The results suggest that the carbonylation of proteins at the hair surface with aldehydes decreases hydrophobicity and promotes further damage as does bleaching. |
