Cold Cream

Definition of Cold Cream:

• Cold Cream are water-in-oil (W/O) emulsions, traditionally used for cleansing and moisturizing the skin.
• They provide a cooling sensation upon application due to the evaporation of water from the skin surface.

Key Ingredients:

1. Oils and Fats: Provide emolliency (e.g., mineral oil, beeswax).
2. Water: Hydrating phase.
3. Emulsifiers: Stabilize the emulsion (e.g., borax, lanolin).
4. Preservatives and Fragrance: Enhance product shelf life and appeal.

Formulation and Preparation:

1. Preparation of Oil Phase

   • Waxes and oil-soluble components are heated together until melted (often 65–75 °C).

2. Preparation of Aqueous Phase

   • Water and water-soluble ingredients (e.g., borax, glycerin) are heated to about the same temperature as the oil phase.

3. Emulsification

   • The aqueous phase is slowly added to the oil phase under continuous stirring to form a W/O emulsion.

4. Cooling

   • The emulsion is cooled with gentle stirring until it thickens and stabilizes.
   • Perfumes or heat-sensitive ingredients are added below 40 °C.

5. Final Checks

   • pH, consistency, and microbial tests are performed before packaging in jars or tubes.
