Sodium hydroxide is caustic, and it could be in low enough concentrations that it only is affecting the more sensitive skin of the baby. | |

They are much less irritating, but have more potential as allergen. You can try cationic surfactants as well. Problem: even if they model naturally occurring compounds, I doubt any of them is completely green, so I do not think you'll find one in green cosmetic markets. | |

There are cationic surfactants and non-ionic surfactants as well. Traditional soaps also gives slightly basic solutions, that is not best for skin. This is the reason one should look skeptically on natural soaps, despite their, ergh, 'naturality'. | |

| Aug 4, 2012 at 21:15 | comment | added | Julie Leung | This is why I wondered whether what the cocoate ion looks like compared with the olivate ion, and if the cocoate ion is better at producing similar results that affect membrane permeability on an eczematic person (similar to other coconut-derived surfactants like SLS) than olivate? | |
| Aug 4, 2012 at 21:13 | comment | added | Julie Leung | The soaps we are using containing cocoate had no other perfumes/pigments that he could be reacting to (one he reacted to contained only saponified coconut oil, palm oil, and olive oil!). The pH thing is a possibility since some soaps are more drying than others and I wonder if more alkaline soaps cause irritation to the extent that it causes eczema on my toddler (because it seems to cause excessive drying to the point of discomfort, but intact skin) on me. | |
| Aug 4, 2012 at 21:10 | comment | added | Julie Leung | Hi and thanks for your response. I don't think my toddler is allergic to the soap with cocoate but rather believe his skin is damaged by the cocoate ions in a similar way as SLS and harsher detergents relating to increasing membrane permeability (see <solveeczema.org/thesolution.html#membrane_permeability>). Many other children whose parents have implemented the methods have have had their eczema cured by using soaps (not detergents) even when these soaps contain cocoate but my son seem to have an extra (rare) sensitivity. | |
