|本文=Neutral dishwashing detergent does not remove grime by neutralizing it; its surfactants make grease mix with water so it washes away.
|なぜ=Surfactants act at the boundary between water and oil, wrapping the grease into tiny droplets (emulsifying it) and dispersing it in the water.
|ジャンル=生活・家事
|ファクト度=A
|ファクト度の根拠=Confirmed by the Japan Soap and Detergent Association
|ネタ度=B

|根拠2要約=The same association: dish detergents emulsify and disperse grease with surfactants; dish detergents that can also wash vegetables and fruit are required by the Food Sanitation Act to be neutral, pH 6.0–8.0; skin irritation depends more on the surfactant composition than on pH
|根拠2格付け=二次
|補足=It is neutral because dish detergents that can also wash vegetables and fruit are required by the Food Sanitation Act to be neutral (pH 6.0–8.0). The industry body explains that skin irritation depends more on the surfactant mix than on pH. Weakly acidic and weakly alkaline dish detergents also exist today.
