Cleansing Balm Formulation with PEG-10 Isostearate and Oilsify 15

Both PEG-10 Isostearate and Oilsify 15 are emulsifiers commonly used in cleansing oil and balm formulations to help remove makeup and rinse cleanly with water.

Role of Ingredients:

• PEG-10 Isostearate: Used in cleansing balm formulations to help dissolve and remove makeup, particularly in water-in-oil systems. It helps the balm emulsify when water is added.
• Oilsify 15: An oil-emulsifier effective in cleansing oils for removing makeup. It also helps the oil phase emulsify with water.

Mixing Steps:

In a cleansing balm, both PEG-10 Isostearate and Oilsify 15 are typically added to the oil phase. A basic cleansing balm formulation usually involves:

1. Combining all oil-soluble ingredients, including liquid oils, solid oils/butters, waxes (if used for texture), PEG-10 Isostearate, and Oilsify 15.
2. Gently heating the mixture to melt any solid components (waxes, solid oils/butters) until the phase is clear and uniform.
3. Mixing thoroughly to ensure all ingredients, especially the emulsifiers, are well dispersed.
4. Pouring the mixture into containers and allowing it to cool and solidify into a balm texture.

Usage Rates:

• PEG-10 Isostearate: Recommended usage rate is 1-30%.
• Oilsify 15: Recommended usage rate is 5-20%, with 10-15% being a common recommendation.

The specific percentages for a complete formula will depend on the desired texture and cleansing performance, and would require testing.

Heat Stability:

The product descriptions for both ingredients recommend storing them at room temperature and avoiding heat and sunlight for long-term storage. However, they are designed to be used in oil-based formulations which often require heating to melt solid ingredients like waxes or butters.

While a specific maximum processing temperature is not stated in the descriptions, these emulsifiers are generally stable enough to be incorporated into the heated oil phase during the manufacturing process of a balm, which typically involves temperatures required to melt waxes (e.g., 60-80°C). Avoid prolonged exposure to high heat.

For best results, always follow specific formulation guidelines and perform stability testing for your final product.
