About

A soy-derived diamine used primarily as a conditioning ingredient, with some potential for sensitization from soybean allergens.

Soyaminopropyldiamine is derived from soy fatty acids (Glycine max) and functions as a conditioning amine. Soybean-derived ingredients may contain residual proteins that act as allergens for soy-sensitive individuals. The ingredient is not listed on EU Annex II or III. Primary and secondary amine groups can react with skin proteins and potentially cause sensitization, though the risk is considered low at typical use concentrations in rinse-off products. Formulated at acidic pH to minimize free amine availability.

Skin benefits

  • antistatic conditioning
  • improved hair shine
  • emollient feel from soy fatty acids

Known concerns

  • soy allergen disclosure recommended
  • amine reactivity potential
  • sensitization risk at high concentration
