Material Compatibility Rules

Silicone tools and skin oils often interact during body care routines. Different classes of lipids behave differently against platinum cured elastomers. Mineral oils and synthetic silicones dissolve into solid silicone rubber through a process called solvent swelling. Botanical lipids behave differently depending on their molecular structure. Understanding these interactions prevents structural damage to your equipment.

Wax Esters Compared to Free Lipids

Cold-pressed jojoba oil is chemically classified as a long-chain wax ester. Plant squalane is a branched saturated hydrocarbon. Neither of these molecules dissolves platinum cured silicone over short contact periods. However, prolonged submersion or improper storage with oil on the surface can soften the outer skin of the tool.

• Application order: Apply jojoba or squalane oils to the skin for massage routines. Let the oil absorb before introducing silicone tools.
• Immediate wash: If plant oils contact your silicone device, wash the item with soap and warm water right away.
• Forbidden lubricants: Never use silicone fluids (dimethicone, cyclomethicone) as lubricants with silicone devices. Like dissolves like, and fluid silicones will liquefy the solid tool surface.

Maintaining Structural Firmness

A soft or gummy surface on a tool indicates chemical breakdown. Once a polymer matrix swells from solvent intrusion, it cannot be reversed. Keep your lipid bottles and your silicone hardware in separate storage compartments to avoid accidental cross-contact.
