The inner layer that touches the skin with Castor Oil is 100% organic cotton flannel; the outer layer is polypropylene, and the straps are nylon.
The outer polypropylene layer is what makes your pack “less mess”, it’s the same material used in food safe containers like yogurt cups. It can be bonded to other materials either with heat or with chemicals – we use a heat-bonding process to bond it to the organic cotton so no extra chemicals are added.
All less-mess versions of Castor Oil Packs use a protective layer of some sort, whether it be a harsher plastic like vinyl or other. We are consistently innovating our products based on customer feedback and striving for the cleanest materials presently available on the market while being transparent about our manufacturing processes and materials standards.
Our aim is to create a product that bridges time - honouring ancient cleansing, drainage and detox practices with modern day convenience.
We also offer a 100% organic option, which includes an Organic Cotton Castor Oil Pack (without the polypropylene layer) plus an Organic Cotton Strap: https://www.shopqueenofthethrones.com/products/100-organic-cotton-flannel-strap-for-castor-oil-pack
