Oil Milk vs Oil Soap

• Oil Milk (Laureth-4): This ingredient is primarily an emulsifier designed to make oil-based formulas turn into a milky consistency when mixed with water. It does not contain soap or detergent properties itself. It is versatile and can be used in various oil-based products like massage oils or bath oils to create the milky effect upon rinsing.
• Oil Soap (High Foaming Oil-Based Liquid Soap): This is a ready-made soap base specifically formulated for oil-based soaps. It does contain detergent (MIPA-Laureth Sulfate) and provides foaming/cleansing properties. When mixed with water, it also turns milky, but its main function is as a soap base.

Regarding which provides a stronger white milky appearance when wet, Oil Milk is specifically designed for this emulsifying function in oil systems. While Oil Soap also turns milky, Oil Milk's core purpose is to facilitate this milky transformation in oil-based products that are not necessarily soaps. Therefore, Oil Milk is the key ingredient to achieve the desired milky effect in a non-soap oil blend.

Formula for Milk Skin Nourishing Vitamin

Since you want to create a "milk skin nourishing vitamin" for spa use, similar to a product that emulsifies into a milk when wet, using Oil Milk is appropriate. This type of product functions as a nourishing oil blend that is easy to rinse off due to the emulsification.

Here is a suggested basic formula concept:

Basic Milk Skin Nourishing Oil Formula

• Oil Milk (Laureth-4): 15-25%
  • Function: Acts as the emulsifier, causing the oil blend to turn milky when mixed with water for easy rinsing. Use a higher percentage for a more pronounced milky effect and faster emulsification.
• Nourishing Oils: 74-84%
  • Function: Provides skin conditioning and nourishment. You can use a single oil or a blend. Good options include:
    • NaturalProfile™ Sweet Almond Oil (Cold-Pressed): Moisturizing, easily absorbed, rich in vitamins.
    • Jojoba Oil (Golden - Deodorized): Similar to skin's natural sebum, non-greasy, good for all skin types.
    • Rice Bran Oil (High Omega, Refined): Rich in Omega fatty acids and antioxidants, nourishing for skin and hair.
• Vitamin E (Tocopheryl Acetate): 1%
  • Function: Acts as an antioxidant to protect the oils from oxidation and provides skin conditioning benefits.

Mixing Instructions

1. Combine the chosen Nourishing Oil(s) and Oil Milk (Laureth-4) in a container.
2. Mix thoroughly until the blend is uniform and clear.
3. Add Vitamin E (Tocopheryl Acetate) and mix again.
4. (Optional) Add fragrance or essential oils at this stage if desired, typically at 0.1-1%.
5. Pour into suitable packaging.

How to Use

Apply the oil blend directly to dry skin and massage. When ready to rinse, add a small amount of water, and the oil will transform into a white milk. Continue adding water and rinsing until the product is completely washed off, leaving the skin feeling soft and nourished.
