Powerful Clean | Plastic-Free | Choose Your Size | Handcrafted in Small Batches
Most laundry detergents that call themselves natural still use synthetic detergent bases, optical brighteners, or synthetic fragrance. This one doesn't use any of them. Six ingredients, named on the label, built around cold process coconut soap — a cleaning base that's been used for generations and leaves no synthetic residue on fabric or skin.
Available in a 16 oz trial size and a 2 lb refill size. Same formula, same seven scents. If you have a coconut allergy or sensitivity, the coconut-free tallow formula is worth looking at instead.
Choose Your Size
16 oz (~40 front-load washes / ~20 top-load washes) - A practical starting size at $14.99. Covers roughly 5–6 weeks of daily front-load washing. Good for trying the formula before committing to the larger bag.
2 lb (~80 front-load washes / ~40 top-load washes) - The everyday refill size at $24.99. Roughly 2.5 months of daily front-load washing. Subscribe & Save is available so you never run out.
What Makes This Different
Made Fresh in Small Batches
Handcrafted in Flagler County, FL. Not mass-produced, not warehoused for months. Consistent quality in every bag because every batch gets attention.
True Ingredient Transparency
Six ingredients, no filler, nothing hidden. You know exactly what's cleaning your family's clothes.
Cost-Effective Per Load
The 16 oz runs about $0.37 per front-load wash. The 2 lb drops that to about $0.31. Compare that to $0.30+ per commercial pod, without the synthetic fillers or optical brighteners that come with them.
Essential Oils Only
All scented varieties use 100% pure essential oils. No synthetic fragrance, no "fragrance" listed as a single mystery ingredient.
Plastic-Free Packaging
Kraft paper bag. No plastic jugs, no single-use pods.
Works in All Machines
HE compatible, septic safe, cold water effective. Low-sudsing formula designed for modern machines.
Choose Your Scent
All scented varieties use 100% pure essential oils.
Unscented
Pure, fragrance-free formula. Nothing added. Right for scent sensitivities or anyone who prefers their laundry to come out smelling like clean fabric.
Citrus Coast
Bright, energizing blend of bergamot and sweet orange essential oils.
Rosemary Lemon
Herbaceous rosemary meets bright lemon for an uplifting, clean scent.
Lemon Basil
Zesty citrus meets aromatic herbs. Complex, fresh, and a little unexpected.
Lemongrass
Bright, citrusy lemongrass essential oil. Clean and naturally uplifting with a touch of herbal sweetness.
Lavender Serenity
Classic, calming lavender essential oil. Works especially well on bedding and everyday loads.
Eucalyptus & Mint
Crisp and clarifying. Naturally invigorating without being sharp.
How to Use
Front-Load Machines
1 tablespoon per load - 16 oz bag = ~40 loads / 2 lb bag = ~80 loads
Top-Load Machines
2 tablespoons per load - 16 oz bag = ~20 loads / 2 lb bag = ~40 loads
Heavily Soiled Items
Use 2 tablespoons regardless of machine type for extra cleaning power.
Works in cold water. Cold washing is gentler on fabric and saves energy, no performance trade-off with this formula.

Frequently Asked Questions
What is the difference between the 16 oz and the 2 lb size?
Same formula, same scents. The 16 oz gives approximately 40 front-load washes or 20 top-load washes and is a good way to try the formula before committing to the larger bag. The 2 lb gives approximately 80 front-load washes or 40 top-load washes and is the better value for ongoing use.
Is this laundry powder safe for sensitive skin?
Yes. The formula is built on cold process coconut soap with no synthetic fragrance, no optical brighteners, and no synthetic dyes. For people with a coconut allergy or sensitivity, the coconut-free tallow formula is the better choice, as this standard formula does use coconut soap as its cleaning base.
Is this safe for HE washing machines?
Yes. This is a low-sudsing formula designed for high-efficiency front-load and top-load machines. Use 1 tablespoon per front-load wash, 2 tablespoons for top-load or heavily soiled items.
Will this work in cold water?
Yes. The formula dissolves and cleans effectively in all water temperatures including cold. Cold water washing is gentler on fabrics and saves energy — there's no performance trade-off with this powder.
Is this safe for cloth diapers?
Yes. Use the standard recommended amount and skip fabric softeners, which reduce absorbency over time.
Is this septic safe?
Yes. The formula is septic-safe and won't disrupt the beneficial bacteria in your system.
Does this work in hard water?
Yes. The sodium carbonate (washing soda) in the formula helps counteract hard water minerals. For very hard water, a small extra amount of powder helps the formula perform at its best.
Do the scented varieties leave fragrance on clothes?
The essential oil scents leave a light, clean scent on dry laundry — not the synthetic fragrance cloud you get from commercial detergents. It's present but not overwhelming, and fades naturally as clothes air out.
