Understanding the Difference Between Hot and Cold Pressed Soaps

When it comes to soap-making, the method used can dramatically influence the soap's texture, longevity, and skin-nourishing properties. Here’s a breakdown of the differences between cold-pressed soaps and hot-pressed soaps, two popular options for high-quality, artisanal soap lovers.

Cold-Pressed Soaps: Slow and Steady Perfection

Cold-pressed soaps are crafted using a careful balance of oils like olive oil, lard, and coconut oil combined with a lye-water solution. This method preserves the natural qualities of the ingredients and produces a creamy, moisturizing bar of soap.

The 4-6 Week Saponification Process

  1. Mixing and Molding: The oils are blended with the lye-water solution. This initiates the process of saponification, a chemical reaction where fats and oils transform into soap and glycerin.
  2. Curing: Once poured into molds, the soap hardens over 24-48 hours, but it’s not ready to use yet!
  3. Drying and Aging: The bars are carefully placed in a well-ventilated area to cure for 4-6 weeks. During this time, the soap fully saponifies, hardens, and becomes gentler for the skin. This curing period also enhances the soap’s longevity and lather quality.

The result? A bar of soap with a smooth texture, a naturally mild scent, and deeply hydrating properties that are perfect for everyday use.

Hot-Pressed Soaps: A Faster Approach

Hot-pressed soaps are made with a slightly different process that speeds up the curing time. Instead of letting the soap naturally saponify over weeks, heat is applied to accelerate the reaction. Commonly used bases for hot-pressed soaps include cocoa butter, mango butter, shea butter, or a luxurious goat milk base.

The Process

  1. Cooking: After the oils and lye-water solution are mixed, the soap mixture is heated, often in a slow cooker or double boiler. This ensures the saponification process is complete during the cooking phase.
  2. Molding and Cooling: Once the mixture thickens and becomes paste-like, it is poured into molds.
  3. Ready to Use: After cooling for a few hours, the soap is ready for use, eliminating the long curing process.

Hot-pressed soaps are known for their rich, creamy texture and quick availability. The heat also allows for adding delicate ingredients, like essential oils or natural exfoliants, without fear of degradation during the curing process.

Which Soap is Right for You?

  • Cold-Pressed Soaps: Ideal for those who prioritize tradition, long-lasting bars, and skin-friendly natural oils. These are especially great for people with sensitive or dry skin.
  • Hot-Pressed Soaps: Perfect for anyone looking for rich, luxurious lather and faster availability, often featuring indulgent ingredients like cocoa butter or goat milk.

Both types of soap deliver high-quality cleansing and skin-nourishing benefits, but the choice comes down to personal preference and skincare needs. Explore our wide range of hot and cold-pressed soaps to find your perfect match!
