The ISO 1067 standard, developed by the International Organization for Standardization (ISO) , provides a method for determining the content of unsaponifiable, non-saponifiable, and unsaponifiable substances in commercial soaps, excluding compound products. According to this standard, the substance soluble in hexane is extracted, and the extracted free fatty acids are titrated with a potassium hydroxide solution. This neutralization allows for the saponification of the hexane-soluble products and the extraction of the unsaponifiable substance using hexane. The full name of this standard is: ISO 1067: 1974 Soap analysis - Determination of unsaponifiable, non-saponifiable, and unsaponifiable substances.
This test method is applied to determine the composition of products that are soluble in hexane or light petroleum (unsaponifiable + unsaponifiable substance) and saponifiable (unsaponifiable saponifiable substance), excluding free fatty acids. However, it is not applied to soaps enriched with sterols or long-chain alcohols, or soaps containing perfume.
This method is based on the following principles:
In the tests and analyzes carried out in our organization, which has a wide range of technological equipment, trained and experienced staff and applies the most modern methods, national and international standards and legal regulations in force are complied with. Among the numerous tests carried out in this context, there are also services for the determination of unsaponifiable, unsaponifiable and unsaponifiable matter.
