Formulating a successful Cold Process (CP) lotion begins with selecting the right oils and butters. These ingredients not only define the texture and absorption of your product but also influence its moisturizing properties, shelf life, and skin feel. Whether you're an experienced formulator or just starting your skincare line, understanding how to choose the best oils and butters for CP lotions is essential.
In this guide, we’ll explore the best oils and butters for cold process lotions, how to balance them in a formula, and tips to make your lotion stand out.
What is Cold Process Lotion?
Unlike hot process lotions, Cold Process (CP) lotions are emulsified at room temperature or with minimal heat. This method helps preserve the nutrients in natural oils and butters, making it ideal for formulations that focus on skin-loving ingredients and natural skincare benefits.
Because you're not heating the ingredients to high temperatures, it's critical to use stable, compatible oils and butters that blend well and offer lasting hydration without separation.
Why Choosing the Right Oils and Butters Matters
* Texture & Absorption: The consistency of your lotion depends on the fatty acid profile of the oils and butters.
* Skin Type Compatibility: Dry, oily, sensitive, or acne-prone skin may react differently to various oils.
* Shelf Life: Some oils oxidize faster than others, affecting product stability.
* Sensory Feel: From greasy to silky, the right combination creates a luxurious user experience.
* Marketing Appeal: Exotic butters or oils can boost your product’s appeal in a crowded market.

Tips for Successful CP Lotion Formulation
1. Use an Emulsifier Suitable for Cold Process
Opt for emulsifiers like Olivem 1000, Emulsense HC, or Montanov 68 MB, which work well without high heat.
2. Include a Natural Preservative
Cold Process lotions are more prone to microbial growth. Use broad-spectrum preservatives like Geogard ECT or Leucidal SF Complete.
3. Mind the pH
Keep your lotion pH between 4.5 and 5.5 for optimal skin compatibility and preservative performance.
4. Test for Stability
Before scaling up, perform stability testing:
* Freeze-thaw cycles
* Room temperature storage
* Check for separation or rancidity
