Emulsifier Recommendation for Mineral Oil and IPM Formulation

Question

In a formulation containing `Mineral Oil` and `IPM`, I am unsure which `Emulsifier` to use. Could you please provide recommendations?

Answer 1

Emulsifier Recommendations for Mineral Oil and IPM Formulation

For a formulation containing Mineral Oil and IPM, you will likely need an oil-in-water (O/W) emulsifier to create a stable emulsion with a water phase. Based on your ingredients, here are a couple of suitable oil-in-water emulsifiers:

Ceteareth-10: This is an oil-in-water emulsifier with an HLB of 12-13. It is typically used at a rate of 0.5-30% and should be mixed in the oil phase, heated to 70-80°C to melt.
C12-15 Pareth-12: This is a non-ionic oil-in-water emulsifier with an approximate HLB of 14.4. It is commonly used at a rate of 1-10% and is mixed with the oil phase.

Both of these emulsifiers can help stabilize the oil phase containing Mineral Oil and IPM within the water phase of your formulation.

Update 2026-05-24

Ceteareth-10 and C12-15 Pareth-12 remain practical conventional O/W non-ionic emulsifier options for a formula containing Mineral Oil and IPM, assuming the intended system is oil-in-water. However, they should not be treated as guaranteed to stabilize every formula by themselves. The best emulsifier system depends on the total oil phase, target texture, viscosity/structure, and processing.

For a light lotion with a low oil phase, a high-HLB emulsifier may be sufficient after testing. For a richer cream or higher Mineral Oil + IPM level, add suitable structure such as fatty alcohol, a glyceryl stearate/PEG-stearate type co-emulsifier, polymer thickener, or use an all-in-one O/W cream maker. HLB is only a screening guide; confirm the final formula with stability testing such as heat-cool cycles, centrifuge, and elevated-temperature storage.
