Epsom Salt

Categories: Bathroom Cleaning, Hospitality & Healthcare, Personal Care, Raw Material, Agriculture, Greenhouse Tags: Bath, Bath Salts, Foot Soak, Lawn, Magnesium Deficiency, Muscle, Muscle Tension, Personal Care, Relax, Relaxation, Relaxing Bath Soak, Stress
  • Description

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.

CAS No.
10034-99-8
Formula
MgSO₄·7H₂O
pH (5% solution)
~6.0 – 7.0 (neutral)
Solubility
710 g/L @ 20°C
Purity
≥99% heptahydrate

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.

Other Applications

Safety & Handling
Epsom Salt is a low-hazard material classified as non-toxic under normal conditions of use. Avoid prolonged inhalation of fine dust. Not for internal consumption unless specifically sold as a food-grade or pharmaceutical-grade product — consult a healthcare professional before any medicinal use. Store in a cool, dry place in a sealed container to prevent caking. Refer to the product Safety Data Sheet (SDS) for full GHS classification and handling guidance.
