Understanding Laureth-4 and Oleth-5

Both Laureth-4 and Oleth-5 can function as emulsifiers or dispersants, helping to blend oil and water.

Differences

• Laureth-4 (Oil Milk™): This ingredient is specifically designed for creating oil-based cleansing products that turn into a milky liquid upon contact with water. It helps oils disperse effectively in water for cleansing.
• Oleth-5: This is a more general-purpose emulsifier and thickener used in various formulations like creams, lotions, serums, and gels to create stable emulsions.

Milky Appearance

Based on the product descriptions, Laureth-4 (Oil Milk™) is highlighted for its ability to create a milky white or opaque appearance when the oil formulation containing it comes into contact with water. While Oleth-5 can help emulsify oils, the characteristic milky transformation upon dilution is specifically associated with Laureth-4 (Oil Milk™).
