Essential oils have become a go-to for anyone exploring natural wellness and beauty. From diffusers to massage oils, they’ve found their way into our homes, including into homemade soap formulations.
If you’re curious about how to make natural soap with essential oils or want to find the best essential oils for soap making, you’re in the right place. In this guide, we’ll explore how to create DIY essential oil soap using simple ingredients, safe ratios, and easy melt and pour recipes.
Why use essential oils in soap recipes?
Essential oils don’t just smell incredible, they also bring natural skin benefits depending on the oil you choose. From calming lavender to clarifying tea tree, essential oils turn a plain soap bar into a luxurious aromatherapy experience.
Perfect for anyone starting out with DIY soap making, essential oils offer an easy way to create homemade soap recipes with a personal touch, whilst avoiding synthetic fragrances and harsh ingredients.
Best essential oils for soap making
Not sure which oils to choose? Here are some of the most-loved essential oils for handmade soap:
Calming, anti-inflammatory, great for all skin types.
Energising and brightening; use in moderation for sensitive skin.
A luxurious floral with balancing properties.
Antibacterial, ideal for blemish-prone or oily skin.
Great for balancing oil and uplifting mood.
Gentle and soothing for sensitive skin.

Deeply relaxing with a rich, smoky aroma.

Essential oil ratios for soap
Essential oils are highly concentrated and should always be used with care in soap making.
A commonly recommended usage rate for wash-off products like soap is up to 3% essential oils for body soap. This guideline is based on general safety recommendations from sources like the International Fragrance Association (IFRA) and widely accepted practices in natural skincare formulation.
However, essential oils vary in potency. Some oils (eg. cinnamon or clove) should be used at much lower percentages, while others (eg. lavender) are generally gentler on the skin.
We always recommend checking the IFRA usage limits for each essential oil and doing your own research before formulating. You can also start lower (1–2%) if you're working with sensitive skin types.
