Washing your hands is something we all do multiple times a day, but most conventional hand soaps are full of synthetic fragrances, preservatives, and chemicals. Making your own custom unscented castile hand soap at home is a great way to control exactly what touches your skin while saving money and reducing plastic waste. Whipping up a batch of simple, natural hand soap takes minimal time and ingredients. Read on to learn the process of crafting healthy, environmentally-friendly, tailored cleansers for your household! Whether you want to gently cleanse sensitive skin or add exfoliating properties, the options abound with homemade castile soap.

The Benefits of Making Your Own Unscented Castile Hand Soap

Crafting DIY castile hand soap has many advantages over buying conventional soap. From saving money to controlling ingredients, here are the top reasons to whip up your own custom, unscented cleanser:

Saving Money

Making it yourself saves a significant amount of money compared to purchasing premade natural liquid soap. You can batch-make soap for just pennies per ounce. The ingredients, like oils, lye, and essential oils, are affordable when bought in bulk. Creating 5–10 batches at once reduces costs further through economies of scale.

Controlling Ingredients

Mixing your own soap means you decide which ingredients to use and avoid. You can steer clear of common irritants and only use plant-based, non-toxic oils and butters that nourish skin. It’s easy to keep soap fragrance-free and free of chemicals.

Customizing for Your Needs

The DIY process allows complete personalization for your household. Add exfoliating oatmeal for scrubbing power or moisture-locking shea butter for dry skin. Tailor soap to be suitable for sensitive skin issues like eczema. Tweak oils to be extra gentle or extra cleansing.

Reducing Waste

Making soap from scratch cuts down on single-use plastic waste from liquid soap packaging and pumps. Just mix up a large batch and pour it into reusable glass bottles or jars. Any leftover soap scraps can also be repurposed for future batches.

What You Need to Make Unscented Castile Soap

Creating your own unscented castile hand soap is simple with just a few ingredients, basic equipment, and some safety know-how. Here is what you need to begin DIYing natural liquid soaps:

Ingredients

The ingredient list is short for basic homemade cleansers. Key components include:

  • A “lye liquid” created by mixing sodium hydroxide (lye) with water 
  • Oils such as olive, coconut, almond, or castor oil
  • Essential oils or extracts (optional)

The lye and oils trigger a chemical reaction called saponification, which transforms the ingredients into soap during mixing and curing. Different amounts and types of fatty oils impact the benefits and properties of the final soap product, like moisturization or cleansing power. 

Equipment

You don’t need much special equipment. The basic homemade soap-making toolkit looks like this:

  • A digital scale for carefully weighing out ingredients
  • A thermometer to accurately track ingredient temperatures  
  • Rubber gloves and safety goggles for protection
  • Silicone soap molds or DIY wooden molds
  • Mixing containers and equipment like a stick blender

Safety Precautions

There are a few key precautions to take when making soap from scratch at home:

  • Always wear gloves and goggles when handling lye.
  • Avoid contamination or contact between raw lye and skin/eyes
  • Carefully calculate the amounts of lye and oils.
  • Mix and cure soap in a well-ventilated area.
  • Keep kids and pets away from your workspace.

Follow basic safety protocols and lye-handling techniques for a smooth, incident-free DIY castile soap-making process.

Tips for Customizing Your Homemade Unscented Castile Soap

One of the best facets of creating your own DIY castile hand soap is customizing each batch to suit your personal needs and preferences. Here are simple ways to tailor your unscented soaps:

Varying the Oils Substitute different natural oils to produce soaps with specialized properties. Add shea or cocoa butter for ultra-moisturizing bars. Use 100% olive oil to make pure castile soap. Play with ratios of hard and soft oils to tweak lather and cleansing strength.

Adding Exfoliants Stir in dry ingredients like oatmeal, salt crystals, or coffee grounds to give your soap a scrubbing muscle for removing dirt, grime, or dead skin cells. Use fine or coarse grains, depending on the desired exfoliation level.

Coloring Naturally Skip artificial dyes but lightly tint soaps with clays, activated charcoal, matcha powder, turmeric, or plant-based infusions from ingredients like carrot, beetroot, or rosehip powder. A little goes a long way for natural color.

Storing and Use of Your Homemade Soap

Once your homemade castile hand soap finishes the 4-6-week curing period, it’s ready to use and enjoy! Here are tips for storing and maximizing your custom cleansing bars:

To extend shelf life, store excess soap in an airtight container out of direct light. Fully cured bars will last for many years if kept dry between uses. Large batch leftovers can also be re-melted and poured into different molds for DIY soap recycling.

When ready to use, cut the soap base into smaller bars if it was created in slab molds. Otherwise, leave gently formed soap intact inside jars or silicone molds. Transfer a piece to the sink or shower and swirl slightly damp hands over the bar to work up a nice lather before washing. Rinse thoroughly.

If preferred as a liquid, simply grate down cured soap bars into an old foaming dispenser bottle, then dilute in filtered water until desired consistency is reached. This makes for an easy zero-waste handwashing option.

Follow basic home storage guidelines, and your custom castile soap will remain effectively cleansing and fresh for numerous refills. The options are wide open when you make them yourself!
