Lemon: the bright yellow citrus fruit that adds a zing to your lemonade, a tang to your salad dressing, and a fresh scent to your cleaning products. But did you know that this humble fruit can also be a fantastic addition to your homemade soaps? Using lemon in soap making is a great way to add natural fragrance, color, and cleansing properties to your creations.
Why Lemon? The Benefits of Adding Citrus to Your Soap
Before we dive into the how-to, let’s explore why you should consider using lemon in your soap. Lemon offers a range of benefits that can elevate your soap from ordinary to extraordinary:
- Natural fragrance: Lemon essential oil provides a refreshing and uplifting scent that can invigorate your senses.
- Natural color: Lemon zest can impart a beautiful yellow hue to your soap, adding a touch of sunshine to your daily routine.
- Exfoliation: The texture of lemon zest can provide gentle exfoliation, helping to remove dead skin cells and leave your skin feeling smooth.
- Cleansing properties: Lemon juice and essential oil possess natural cleansing properties that can help to remove dirt and oil from the skin.
Choosing Your Lemon: Essential Oil, Juice, or Zest?
When it comes to incorporating lemon into your soap, you have several options:
- Lemon Essential Oil: This is the most concentrated form of lemon and provides the strongest scent and cleansing properties. Be sure to use pure essential oil and not fragrance oil for the best results.
- Lemon Juice: Fresh lemon juice can be added to your soap recipe for its cleansing properties. However, it can also lower the pH of your soap, so use it sparingly.
- Lemon Zest: The grated outer peel of the lemon adds color, fragrance, and a gentle exfoliating texture to your soap.
Cold Process Lemon Soap: A Step-by-Step Recipe
One popular method for making lemon soap is the cold process. Here’s a basic recipe to get you started:
Ingredients:
- 375 g olive oil
- 25 g castor oil
- 55 g caustic soda
- 100 g lemon juice
- 1 teaspoon sodium lactate
- 15 ml lemon essential oil
- Fresh lemon zest
Equipment
- Digital scale
- Non-reactive containers
- Pot
- Stick blender
- Soap mold
- Gloves and goggles
Instructions:
- Measure and combine lye and water: In separate containers, measure out the lye and water using a digital scale. Slowly add the lye to the water, stirring until dissolved. Be careful of fumes and heat. Set aside to cool in a safe place.
- Melt oils: Measure the oils in separate containers and combine them in a pot. Add 1 teaspoon of lemon zest. Melt over medium-low heat until fully melted and around 130-140 degrees Fahrenheit. Remove from heat and set aside to cool.
- Combine and blend: Check the temperature of both solutions. They should be around 90-100 degrees Fahrenheit. Add the sodium lactate to the cooled lye water. Put on gloves and goggles. Pour the lye solution into the melted oils and blend with a stick blender until you reach trace.
- Add fragrance and zest: Once trace is reached, add the lemon essential oil and remaining lemon zest. Stir in by hand.
- Pour into mold: Immediately pour the soap batter into the mold. Place in a turned-off oven or other draft-free place and allow to set for 24 hours.
- Cut and cure: Turn out the loaf of soap and slice it into bars. Allow the bars to cure in a well-ventilated space for at least 2 weeks before using. For a longer-lasting bar, cure for 4 weeks.
Melt and Pour Lemon Soap: A Quick and Easy Alternative
If you’re new to soap making or prefer a faster method, melt and pour soap is a great option:
Ingredients:
- 1 1/2 cups goat’s milk, shea, or glycerin soap base
- 4-6 drops lemon essential oil
- Lemon zest
Equipment:
- Microwave-safe measuring cup
- Soap molds
Instructions:
- Melt soap base: Cut the soap base into cubes and microwave in 30-second intervals until melted.
- Add lemon: Add lemon essential oil and lemon zest to the melted soap base; stir well.
- Pour into molds: Pour the mixture into soap molds and allow to harden for at least one hour.
- Release and enjoy: Press the mold to release the soap.
Tips and Tricks for Perfect Lemon Soap
- Use fresh ingredients: For the best scent and color, use fresh lemon zest and high-quality lemon essential oil.
- Control the temperature: When using the cold process method, ensure that your lye solution and oils are within the recommended temperature range to avoid issues with saponification.
- Add lemon zest in stages: Add some of the lemon zest to the oils before blending and the rest after trace to create a speckled, lemony look.
- Consider using yellow soap dye: If you want a more vibrant yellow color, consider adding yellow soap dye in addition to lemon zest.
- Don’t add too much lemon juice: Adding too much lemon juice can lower the pH of your soap and make it acidic.
- Cure your soap: Curing your soap for several weeks allows excess water to evaporate, resulting in a harder, longer-lasting bar.
- Store properly: Store your finished lemon soap on a breathable soap dish to allow it to dry fully between uses.
Precautions
- Always wear gloves and goggles when working with lye.
- Work in a well-ventilated area when combining lye and water.
- Keep lye solution away from children and pets.
