Kirk's Natural has been making all-natural, coconut oil castile bar soap since 1839
Once known as the "soap of royalty" because of its luxurious lather and gentle qualities, castile soap—from Castile, Spain—today refers to any vegetable-based soap. Kirk's Natural has been helping everyone feel like kings and queens since 1839 with its pure, botanical, castile soap at affordable prices.
With a centuries-old, time-honored process of combining coconut oil and caustic soda (from sea salt), Kirk's Natural bar soap contains only four ingredients: coconut oil, soap of coconut, vegetable glycerin and water. The vegetable glycerin is a natural part of coconut oil, and while many soap companies remove it during manufacturing, Kirk's Natural leaves it in for its unique moisturizing properties.
Kirk's Natural castile soap is pure coconut oil bar soap. Every bar is:
- Free of synthetic detergents
- Free of animal products/never tested on animals
- Hypoallergenic
- Biodegradable
Besides bar soap, Kirk's Natural makes liquid castile soap in a convenient 16-ounce dispenser bottle, plus castile shampoo, conditioner and body wash.
Kirk's Natural castile soap works into a creamy lather in even the hardest water, and never leaves drying residue.
