lactic acid in a solid shampoo to acidify the ph
I have seen a commercial solid shampoo with this INCI: Sodium cocoyl isethionate, sodium coco-sulfate, stearic acid, disodium sulfosuccinate, stearic acid, theobroma cacao (cocoa) butter, cocos nucifera (coconut) oil, glycerine, cetearyl alcohol, lime (Citrus aurantifolia), rosemary (Rosmarinus officinalis) & sweet orange (Citrus sinensis) essential oils, juniper (Juniperus communis) extract, mica, lactic acid.
The main ingredient is SCI, but I have read ( I can´t remember where) that adding lactic acid to it could make the sci react, lowering its cleaning power. Is that true? What do you think about this formula? Do you think it is well constructed? Thank you.
