Creating a Cold Process Skin Cream

To make a skin cream without using heat, you will need a cold-process emulsifier and a suitable preservative. You will also need to add moisturizing ingredients to achieve a soft and hydrated feel.

Emulsifiers (สารประสานเนื้อครีม)

Emulsifiers are typically found under categories like "Cream texture binders" or "Texture creators". For making cream without heat, consider these options:

• Light Cream Maker™: This is an excellent choice for beginners. It works without heat, creates a light, smooth texture that absorbs easily, can handle up to 20% oil, and has some tolerance for electrolytes. Recommended usage is typically 1-1.5%.
• Easy Cream Maker™: A more economical option that also works without heat. It creates a slightly heavier texture and can handle up to 10% oil. Note that it does not tolerate electrolytes well. Recommended usage is 1-2%.
• CreamMaker EG™: Another cold-process option that acts as a thickener and stabilizer, helping to create a supple gel-cream texture. It can be added to either the oil or water phase.

Soft Cream Maker™ requires heat, so it is not suitable for your requirement.

Preservatives (สารกันบูด)

For a cold-process cream, you need a preservative that can be added at room temperature or below 45°C. Here are some options:

• Global Guard™ 221: A broad-spectrum, water-soluble preservative that can be added at any step as long as the temperature is below 45°C and the pH is between 2-7. It is globally approved and used at a low rate (0.5-1.1%).
• Mild Preserved™ COS: Another broad-spectrum, water-soluble preservative suitable for cold process (below 45°C) with a wide pH range of 2-8. It is odorless and used at 0.75-1.5%.
• NaturePreserve™ Ultra: A natural, powder preservative that works in the pH range of 3-6 and is heat tolerant, but can be used in cold process by mixing into the water phase. Note that it should not be used with L-Ascorbic Acid (Vitamin C).

For Soft and Moisturizing Skin

To make your cream soft and moisturizing, you will need to incorporate ingredients like natural oils (e.g., Sweet Almond Oil, Shea Butter), humectants (e.g., Glycerin, Hyaluronic Acid), or specific moisturizing active ingredients.

By selecting a cold-process emulsifier and preservative, along with suitable moisturizing ingredients, you can create a simple skin cream for personal use without needing to heat your formulation.
