Understanding Your Milky Oil Formulation

Thank you for providing the ingredient list for the milky oil product. This type of product is designed to be oil-based but emulsify with water to create a milky texture, often used for cleansing or bathing.

The key ingredients that allow the oil to turn milky when mixed with water are the emulsifiers. In your list, Laureth-4 and Trilaureth-4 Phosphate are likely serving this purpose.

Other ingredients contribute to the overall properties of the product:

• Oils and Emollients (Paraffinum Liquidum, Isopropyl Myristate, Macadamia Nut Oil, Simmondsia Chinensis Seed Oil/Jojoba Oil): These provide the oily base, offering moisturizing and skin-conditioning benefits.
• Protein (Hydrolyzed Milk Protein): Can offer skin-nourishing properties.
• Colorant (CI 77489/Iron Oxides): Used to impart color to the product.
• Antioxidants (Tocopheryl Acetate/Vitamin E, Butylated Hydroxytoluene/BHT): Help to prevent the oils from oxidizing and extend the product's shelf life.
• Preservative (DMDM Hydantoin): Protects the formulation from microbial growth.

Regarding Formulation Proportions

While I can identify the function of these ingredients, I cannot provide you with the exact proportions used in the specific brand's product you listed. Formulations are proprietary.

However, based on general cosmetic formulation principles and the typical usage of emulsifiers like Laureth-4, they are often used in the range of 10-40% in oil-based systems intended to become milky upon contact with water. The precise amount needed will depend on the specific oils used and the desired degree of emulsification.

Creating a similar product would involve experimenting with different ratios of your oil phase (Paraffinum Liquidum, Isopropyl Myristate, Macadamia Nut Oil, Jojoba Oil, etc.) and the emulsifiers (Laureth-4, Trilaureth-4 Phosphate), starting within the typical usage ranges for the emulsifiers and adjusting as needed to achieve the desired milky effect and stability.

Remember to also include the other functional ingredients like antioxidants and preservatives at their recommended usage rates to ensure the product's stability and safety.
