Why Silicone-Based Lube is Incompatible With Silicone Toys

Silicone-based lubricant acts as a plasticiser and, when absorbed into the item, causes swelling.

Further exposure may make the item very tacky/sticky to the touch. In extreme circumstances, the item might lose cohesive strength and start to fall apart.

Plasticisers work by interfering with the weak bonding between polymer chains. Factors affecting the effect will be length of exposure & how good a solvent the plasticiser is for the polymer.

You should only ever use water-based lubricants, not only to ensure item longevity, but also to prevent personal exposure to plasticisers.
