Castor oil is a plant-derived oil used in a range of topical products.

It appears in handmade soaps, balms, body butters and other cosmetic formulations.

For regular users, the available packaging size can make a significant difference to cost.

Propel Health Australia offers certified organic castor oil in a new 5 L format.

What is castor oil?

Castor oil is obtained from the seeds of the castor plant, Ricinus communis.

The ingredient is identified in cosmetic formulations by its INCI name:

Ricinus Communis Seed Oil.

For more information about castor oil, its processing and ingredient characteristics, Organic Castor Oil Australia provides a dedicated resource.

What does the bulk product contain?

Propel Health Australia’s 5 L product contains one ingredient: castor oil.

The product is:

• Certified organic
• Cold pressed
• Hexane free
• Supplied in a white HDPE jerrycan
• Product of India

It is intended for external use only.

Why buy five litres?

The main consideration is quantity.

A 5 L jerrycan contains the same volume as ten 500 mL bottles.

The listed price is $89, equivalent to $17.80 per litre.

A single 500 mL bottle costs $38.50, equivalent to $77 per litre.

Who might need the larger format?

Soap and cosmetic makers may use castor oil as an ingredient in formulations.

Salons, spas and massage clinics may prefer to refill smaller dispensers.

Households using castor oil regularly may also prefer bulk packaging.

What about storage?

The jerrycan should be stored below 25°C in a cool, dry location away from direct sunlight.

Keep the cap tightly closed.

For regular use, transfer a small amount into a clean glass bottle.

Important safety information

Castor oil is not intended for swallowing.

The product is for external use only.

Patch test before use.

Avoid broken skin and contact with the eyes.

Stop use if irritation occurs.

Pregnant users should consult their doctor or midwife before use.

Where can you find the product?

Propel Health Australia’s castor oil 5 litre page includes the ingredient specification, price and shipping information.

The practical takeaway

A bulk format makes sense when the expected usage justifies the quantity.

Compare the cost per litre, storage requirements and intended application.

The 5 L jerrycan offers a larger quantity of the same organic castor oil sold in smaller retail bottles.
