I’ve always been fascinated by the process of making soap, especially considering the potential benefits and customization that it offers. Soap making, with its rich history and variety of techniques, is a craft that has withstood the test of time. Using baking soda in soap making is an intriguing method that piques my curiosity, as it incorporates a household item renowned for its gentle cleaning properties.

Incorporating natural elements into soap making aligns with my preference for simplicity and sustainability. Essential oils are frequently used to enhance the soap’s aromatic profile as well as to infuse it with therapeutic qualities. When I select essential oils for my baking soda soap, I’m mindful of their effects on skin and their ability to complement the overall cleansing experience.

This personal approach to creating a cleansing bar with baking soda is not just about avoiding harsh chemicals, but also about enjoying the process and knowing exactly what’s touching my skin. My journey in crafting natural soaps has taught me the importance of precision and patience, which I look forward to sharing with others who are eager to try their hand at this fulfilling endeavor.

The Science of Soap Making

In this section, I’ll be explaining the chemistry involved in soap making and how it interacts with our skin through pH levels and the saponification process.

Understanding Saponification

Saponification is a chemical reaction that occurs when a fat or oil reacts with a base, typically sodium hydroxide (lye). This process creates glycerin and soap, transforming the fats into fatty acid salts. The chemistry behind this is fascinating because each type of oil or fat requires a specific ratio of lye to ensure complete saponification. Here’s a simplified outline of the process:

Fats/Oils + Sodium Hydroxide (Lye) → Glycerin + Soap (Fatty Acid Salts)

pH Levels and Skin Health

The pH level of soap is crucial because it directly affects skin health. Our skin has a natural pH balance that leans towards the acidic end of the pH scale, typically around 5.5. Most soap products, due to the nature of the saponification process, have a higher pH, usually between 8 to 10. It’s important to formulate soap with a pH that is gentle on the skin to avoid disrupting this balance. The goal is to make a soap that cleanses without stripping away essential oils or causing irritation.

To maintain skin health, precise measurements and a thorough understanding of the chemistry are key. Careful control of the saponification process ensures that the final soap product is of the right pH to be safe and beneficial for skin use.

Natural Ingredients for Healthy Skin

Creating a homemade soap bar can be both rewarding and beneficial for the skin. By using natural ingredients like olive oil and lavender essential oils, we can craft gentle soap bars designed to moisturize and nourish the skin effectively.

Essential Oils and Plant-Based Fats

In my experience with soap making, certain essentials oils and plant-based fats stand out for their skin benefits. Olive oil, for instance, is a staple due to its moisturizing properties.

Lavender Essential Oil: Not only does it provide a calming scent, but it’s also great for soothing the skin. Purportedly, it has anti-inflammatory and antibacterial properties, which are excellent for a gentle cleanse without stripping the skin’s natural oils.


I opt for these oils because they’re not only effective but also create a soap that’s a luxurious experience for the skin and senses.

Exfoliants and Their Benefits

For exfoliation, using a natural exfoliant is key. It should be effective yet gentle enough not to damage the skin.

Oatmeal: An ingredient like oatmeal can gently remove dead skin cells and provide a mild abrasive element to soap bars. It’s gentle enough for sensitive skin and has the added benefit of being a natural moisturizer.


When these exfoliants are used in combination with hydrating ingredients like olive oil, we get a soap bar that not only cleanses but also revives and replenishes the skin’s natural barrier.

DIY Soap Making Techniques

Making your own soap allows you to control the ingredients and create a product that’s tailored to your preferences. I’ll go over two popular methods and how you can add a personal touch to your homemade soap.

Cold Process vs Melt-And-Pour

In DIY soap making, the cold process and melt-and-pour are two distinct techniques. The cold process is a more traditional method where I combine oils and lye water to start a chemical reaction known as saponification. This process can take several weeks to cure, but it gives me the flexibility to craft soap from scratch.

Melt-and-pour soap is a convenient alternative, using a pre-made soap base that I simply melt, customize, and pour into molds. This method is safer as it doesn’t require the handling of lye, and the soap is ready to use once it hardens.


For cold process soap, safety precautions are crucial. I always wear gloves and goggles when handling lye to prevent any accidents. I also use silicone molds that can withstand the high pH levels during saponification. Unlike cold process soap, melt-and-pour does not need a curing time, making it a quick and easy option for beginners.

Customizing Your Soap

Customizing my soap allows me to create a product that matches my specific desires. I can add various ingredients, such as essential oils, herbs, or exfoliants to both cold process and melt-and-pour soaps. Adjusting the quantity and combination of these additions enables me to design a soap with unique scents, textures, and skin benefits.

💥 Tip: Start with a basic recipe, then slowly experiment with different additives to understand their effects on the soap’s final characteristics.

When I’m making soap, I always consider the properties of each ingredient. For instance, adding too much oil can make the soap too soft, while certain essential oils might accelerate trace in cold process soap, so precise measurements are important. Using quality soap molds can also impact the final product, as they determine the shape and the ease of soap release once it’s set.

Eco-Friendly Cleaning Alternatives

In an effort to maintain a sustainable household, I’ve explored natural cleaning agents, like baking soda and castile soap, known for their environmental benefits. These non-toxic solutions are not only effective at cleaning but also promote a healthier environment within our homes.

Baking Soda in Homemade Soap

Baking soda has gained recognition for its versatility as a cleaning agent. When used in homemade soap, it acts as a gentle abrasive and natural deodorizer. Here is a simple method to create an eco-friendly household soap:

  • Baking Soda: Start with a base of baking soda.
  • Liquid Castile Soap: Add to create suds and cleansing power.
  • Water: Mix with the ingredients for the desired consistency.


This mixture is not only effective for cleaning surfaces but also safe for the environment, making it an excellent option for those looking to reduce harmful chemicals in their cleaning routine.

Castile Soap and Sustainability

Castile soap is celebrated for its sustainability and non-toxic profile, originating from plant oils like olive, hemp, and coconut. The production of castile soap is environmentally friendly, as it biodegrades quickly and is free from synthetic preservatives.

This is a sample bold text.
  • Origin: Made from natural vegetable oils.
  • Eco-Friendly: Free from animal fats and synthetic substances.
  • Biodegradable: Castile soap breaks down easily without polluting the environment.


Using castile soap in homemade cleaning products supports my commitment to sustainability and lessens my household’s environmental impact.
