◆Safety data
■Protein denaturation
Narrowing contributes to reduced protein denaturation
Test Method
Protein: 0.05% albumin solution
Active agent concentration: 1.0% aqueous solution of active ingredient(SLES (sodium laureth sulfate) is measured as a standard)
Bath ratio: albumin aqueous solution/activator aqueous solution = 9/1
Denaturation temperature: 20-25°C x 24 hours
Quantitative method: High performance liquid chromatography (HPLC)

FormulaF*1 CGT: TEA cocoyl glutamate*2 SLES: Sodium laureth sulfate
