Epsom Salt

Epsom Salt (Magnesium Sulphate Heptahydrate) is a naturally occurring mineral compound with a remarkably broad range of applications — from agriculture and horticulture to bath and body care, industrial processing, and cleaning formulations. A white, odourless crystalline solid that dissolves easily in water, it is one of the most widely used mineral salts across both consumer and industrial markets.

Bath & Body Applications

Relaxing Bath Soak Dissolve 1–2 cups in a warm bath and soak for 15–20 minutes. Magnesium is absorbed transdermally, helping to ease muscle tension, reduce soreness, and promote relaxation after physical activity.	Foot Soak Add ½ cup to a basin of warm water. Soothes tired, aching feet, softens skin, and helps reduce foot odour. Particularly effective after long periods of standing or physical work.
Body Scrub Base The coarse crystal texture makes Epsom Salt an ideal exfoliant base. Blend with coconut oil and a fragrance of your choice for a simple, effective body scrub that removes dead skin cells and leaves skin feeling smooth.	Bath Bomb & Salt Formulation A standard ingredient in bath bomb and bath salt manufacturing. Contributes a silky water feel, skin-softening properties, and bulk to finished products without affecting lather or fragrance performance.

Agricultural & Horticultural Applications

Magnesium Deficiency Correction Magnesium is an essential macronutrient and the central atom in chlorophyll. Apply as a soil drench (1 tbsp per litre of water) or foliar spray to correct yellowing leaves and improve photosynthetic efficiency in vegetables, roses, and fruit trees.	Lawn & Garden Fertiliser Broadcast at 35 g per m² or dissolve and apply via irrigation to boost green colour and overall plant vigour. Particularly beneficial on sandy or acidic soils prone to magnesium leaching.
Seed Germination & Transplant Support A dilute solution applied at planting can strengthen cell walls, improve germination rates, and reduce transplant shock. Used by commercial nurseries and home gardeners alike as a low-cost, readily available micronutrient supplement.
