Here’s a basic recipe for preparing a lotion:

Ingredients:
– 3/4 cup of distilled water
– 1/4 cup of oil (such as coconut oil, almond oil, or jojoba oil)
– 1 tablespoon of emulsifying wax
– 1 teaspoon of glycerin (optional, for added moisture)
– Essential oils for fragrance (optional)

Equipment:
– Heat-resistant glass measuring cups
– Mixing spoon
– Blender or hand mixer
– Sterilized container(s) for storing the lotion

Instructions:
1. Prepare Your Work Area: Make sure your work area is clean and sanitized. Wash your hands thoroughly before starting.

2. Sterilize Equipment: Ensure that all equipment, including glass measuring cups and mixing utensils, are clean and sanitized.

3. Heat the Oil and Wax: In a heat-resistant glass measuring cup, combine the oil and emulsifying wax. Place the cup in a pot of simmering water (double boiler method) and heat until the wax is completely melted, stirring occasionally.

4. Warm the Water Phase: In another heat-resistant glass measuring cup, warm the distilled water. You want both the oil and water phases to be at similar temperatures to aid in emulsification.

5. Combine Oil and Water Phases: Slowly pour the warmed water into the melted oil and wax mixture while stirring constantly. This helps to emulsify the ingredients and create a stable mixture.

6. Blend the Mixture: Use a blender or hand mixer to blend the mixture thoroughly. This will help ensure that the oil and water are properly mixed and that the lotion has a consistent texture.

7. Add Optional Ingredients: If you’re using glycerin or essential oils, add them to the mixture and blend again to incorporate.

8. Cooling and Storage: Allow the lotion to cool to room temperature. As it cools, it will thicken. Once cooled, carefully pour the lotion into sterilized containers.

9. Labeling: Label your lotion containers with the date of preparation and any relevant ingredients. This will help you keep track of its shelf life.

10. Usage: Use the lotion as you would any other lotion. Apply it to clean, dry skin as needed.

Remember that this is a basic recipe, and you can customize it by experimenting with different oils, essential oils, and additives to suit your preferences and skin type. It’s important to perform a patch test before using any new lotion on your skin to ensure that you don’t have any adverse reactions.
