Powerful Clean | Minimal Plastic | Choose Your Size | Handcrafted in Small Batches
Plenty of laundry detergents that call themselves natural still rely on a synthetic detergent base, optical brighteners or synthetic fragrance. This one uses none of them. It has six ingredients, all named on the label, built around cold process coconut soap.
It comes in a 1 lb trial size and a 2 lb refill, with the same formula and the same seven scents. If coconut is a concern for your household, see the instead.
Choose Your Size
1 lb (about 40 front-load or 20 top-load washes) - A practical starting size for trying the formula before you commit to the larger bag. At $14.99, it covers roughly 5 to 6 weeks of daily front-load washing.
2 lb (about 80 front-load or 40 top-load washes) - The everyday refill at $24.99, roughly 2.5 months of daily front-load washing. Subscribe & Save takes 15% off and ships every 4, 6, 8 or 12 weeks.
What Makes This Different
Made Fresh in Small Batches
Handcrafted in Flagler County, FL. Not mass-produced and not warehoused for months.
Ingredient Transparency
Six ingredients, no filler. You can read exactly what's cleaning your clothes.
Cost Per Load
The 1 lb runs about $0.37 per front-load wash. The 2 lb drops to about $0.31. Commercial pods start around $0.30 a load and add synthetic fillers, optical brighteners and fragrance.
Essential Oils Only
Scented varieties use pure essential oils. No synthetic fragrance, and no single "fragrance" line hiding the details.
Minimal Plastic Packaging
Kraft paper bag. No plastic jug, no single-use pods.
Works in All Machines
HE compatible, septic safe, effective in cold water. Low-sudsing, so it won't leave buildup.
Choose Your Scent
All scented varieties use 100% pure essential oils, never synthetic fragrance. Every oil is listed by name on the label.
Unscented
Fragrance-free, nothing added. Right for scent sensitivities, or if you like laundry that smells like clean fabric and nothing else.
Citrus
Bergamot and sweet orange. Bright and easy to live with.
Lemon Rosemary
Herbaceous rosemary and bright lemon.
Lemon Basil
Zesty citrus with aromatic herbs. Fresh and a little unexpected.
Lemongrass
Bright, citrusy lemongrass with a touch of herbal sweetness.
Lavender
Classic lavender. Works especially well on bedding and everyday loads.
Eucalyptus & Mint
Crisp and cool without being sharp.
How to Use
Front-Load Machines
1 tablespoon per load. A 1 lb bag is about 40 loads. A 2 lb bag is about 80 loads.
Top-Load Machines
2 tablespoons per load. A 1 lb bag is about 20 loads. A 2 lb bag is about 40 loads.
Heavily Soiled Items
Use 2 tablespoons in any machine type.
Works in cold water. Cold washing is gentler on fabric and saves energy, and this formula cleans well at that temperature.
What's Inside (And What's Not)

Sodium Carbonate (Washing Soda) - A mineral that cuts through grease and grime and helps with hard water.
Sodium Bicarbonate (Baking Soda) - Deodorizes and softens water for better cleaning.
Sodium Borate (borax) - A mineral that boosts overall cleaning power. Curious about borax specifically?
Sodium Percarbonate (Oxygen Bleach) - Brightens colors and whites without chlorine bleach.
Pure Essential Oils - Scented varieties only. Every oil is listed by name on the label.

Frequently Asked Questions
What is the difference between the 1 lb and the 2 lb size?
Same formula, same scents. The 1 lb gives about 40 front-load or 20 top-load washes and is a good way to try it. The 2 lb gives about 80 front-load or 40 top-load washes and is the better value for ongoing use.
Is this laundry powder okay for sensitive skin?
It has no synthetic fragrance, optical brighteners or synthetic dyes, which are common irritants in laundry products. It does contain washing soda and borax, which are alkaline, so the amount matters. Stick to 1 tablespoon per front-load wash, add an extra rinse cycle if your skin is reactive, or choose the unscented version. If coconut is a concern, use the coconut-free tallow formula, since this one uses coconut soap as its base.
Is this safe for HE washing machines?
Yes. It's a low-sudsing formula made for high-efficiency front-load and top-load machines. Use 1 tablespoon per front-load wash and 2 tablespoons for top-load or heavily soiled items.
Will this work in cold water?
Yes. It dissolves and cleans in all water temperatures, including cold. Cold washing is gentler on fabric and saves energy.
Is this safe for cloth diapers?
Yes. Use the standard amount and skip fabric softener, which reduces 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 washing soda helps counter hard water minerals. For very hard water, a small extra amount of powder helps.
Do the scented varieties leave fragrance on clothes?
They leave a light, clean scent on dry laundry that fades naturally as clothes air out. It's an essential oil scent, so expect it to be subtler than a commercial detergent.
