Lavender & Rosemary Natural Handmade Soap

The Day I Burned My Apron (And Learned to Love Lye) Let’s get real: My first soap-making attempt ended with a smoking apron, a panicked call to my chemist cousin, and a batch of soap so harsh it could’ve sanded furniture. But after two years of trial, error, and obsessive note-taking, I’ve cracked the code to luxurious, skin-loving soap that costs less than a latte.

This isn’t just another “mix oils and hope” guide. Here’s what you’ll get:

Ingredients That Actually Work

(No vague “natural” claims – just facts)

The Core Four

IngredientWhy It MattersWhere I Buy Cheap
Olive oilCreates silky lather, won’t dry skinCostco (bulk saves 40%)
Coconut oilHardens bar, boosts bubblesIndian grocery stores (unrefined)
Lye (NaOH)Required for real soap (but vanishes post-saponification)Ace Hardware (Red Devil brand)
Distilled waterPrevents mineral reactionsDollar store (look for “baby water”)

The Flair

  • Lavender buds ($6/6 months supply from local farmers)
  • Fresh rosemary (stolen from my neighbor’s garden – shh!)
  • Lavender essential oil (Bulgarian, 1 tbsp – never “fragrance oil”)

Step-by-Step: The Unfiltered Process

1. Safety First (No Skipping!)

  • Ventilation: Open windows before mixing lye (I learned this after coughing for 3 hours).
  • Gear:
    • Gloves (nitrile > latex – latex melts!)
    • Dollar store swim goggles (lye splashes hurt!)
    • My husband’s old band t-shirt (RIP, Metallica tee)

2. Lye Solution – The Scary Part

  1. In a glass jar, pour 150ml distilled water (room temp)
  2. Slowly add 70g lye while stirring with a chopstick (metal reacts!)
  3. It’ll:
    • Heat to 80°C/176°F
    • Smell like burnt plastic (normal!)
    • Make your cat leave the room (also normal)

3. Oil Prep – Where Magic Begins

  1. vMix 500ml olive oil + 200ml coconut oil
  2. Microwave in 30-sec bursts until 45°C/113°F (test with your wrist)
    • Too hot? Soap will seize.
    • Too cold? Won’t blend.

4. The Moment of Truth

  1. Slowly pour lye into oils
  2. Blend with a $15 stick mixer until “trace” (looks like vanilla pudding)
    • Under-blended: Oily mess
    • Over-blended: Crumbly soap

5. Add Personality

  1. At 40°C/104°F, mix in:
    • 1 tbsp lavender oil
    • 2 tbsp chopped rosemary
  2. Crucial: Wait until mixture cools – essential oils evaporate if added too early!

6. Mold & Pray

  1. Pour into silicone molds (or cleaned yogurt containers)
  2. Top with lavender buds (press gently – they sink otherwise)
  3. Wrap in grandma’s quilt for 24 hrs (insulation = smoother soap)

3 Life-Saving Hacks I Wish I Knew Earlier

  1. Freezer Fix for Impatient People
    Can’t wait 6 weeks? Freeze fresh bars for 48 hrs to speed up curing.
  2. Soap CPR for Failed Batches
    • Too soft? Grate, rebatch with extra lye solution.
    • Too harsh? “Cook” in a crockpot with 10% extra oil.
  3. Scent Lock Trick
    Wrap curing soap in parchment paper – retains 2x more fragrance.

FAQ

1. Can I skip lye?
“Melt-and-pour” bases contain detergents. Real soap NEEDS lye (but it disappears!).

2. Why does my soap have white powder?
Soda ash – harmless but ugly. Prevent by spraying with 91% rubbing alcohol after pouring.

3. Is this safe for tattoos?
Yes! My tattoo artist approves (but avoid scrubbing fresh ink).
