What Makes Sea Spray Solid Dish Soap Different From Every Other "Natural" Option

Most natural dish soaps have a lot in common: plant-derived surfactants on the label, essential oil scent, recycled packaging and a price well above conventional. What separates them is at the formula level, which is hard to see from the outside. So here's what we do and why.

The format itself

Sea Spray Soap dish soap is a solid bar made through cold process saponification, not a liquid in a plastic bottle. That isn't a gimmick. A solid bar doesn't contain water, so it doesn't need the preservative systems liquid soaps require. Methylisothiazolinone, methylchloroisothiazolinone and phenoxyethanol are common in liquid dish soaps because water-based formulas need them to prevent microbial growth. They're also among the more common causes of skin irritation in people with repeated exposure.

No water in the formula means no need for those preservatives. The ingredient list is shorter because it doesn't need chemistry that exists only to solve a problem created by the format.

The oil base

Our standard solid dish soap is built on coconut oil, olive oil, stearic acid and castor oil, each chosen for a specific job. Coconut oil drives cleaning power and foam. Olive oil keeps the bar from feeling harsh. Castor oil extends and stabilizes the lather. The result is a bar that cleans well, holds together through months of daily use and keeps lathering past the first dish.

Our coconut-free version uses tallow, sunflower oil and castor oil. Tallow brings cleaning strength and a bar that lasts. Sunflower gives a milder profile. Castor handles lather. Different base, same principle: every oil earns its place.

The superfat

Cold process soap is made with a calculated excess of oil relative to the lye. This is called the superfat. Some oil in the finished bar doesn't turn into soap, and that leftover oil stays in the bar as a conditioning component. Our superfat is set for hands that wash dishes many times a day: enough to be gentle, not so high that the bar underperforms on grease.

The scent system

Every scented version uses essential oils, named on the ingredient list and never hidden under "fragrance" or "natural fragrance." When the label says Lemon Basil, that's lemon essential oil and basil essential oil. Nothing else makes that scent.

Seven scents plus unscented. The unscented version has no essential oils at all. Unscented means unscented.

Made in small batches in Flagler County, Florida

Every bar is made by hand. Small batches mean each one is checked before it ships. It also means formulas can be updated when better information or ingredients become available, instead of being locked in for a production run of 100,000 units.
