Triclosan, one of the ingredients in Cal Exotics Toy Cleaner, can and does cause allergic reactions. Especially in high concentrations, like in "anti-bacterial soap." The toy cleaner has triclosan in a much smaller concentration than most soaps, but is certainly could be allergenic, either contact dermatitis (meaning cracking or blistering of skin) or even an inhalation allergy, like an asthma attack. I've had patients who can't have products with Triclosan in their houses, and I get eczema from it myself, but only in high concentrations, not from the lower concentration in the Cal Exotics toy cleaner.
I also have to say (as I did in my review of this product) that most use the toy cleaner IN ADDITION to soap and water, or for parts of toys which don't touch mucous membranes. IMO, it's a good product, but not to be used in place of soap and water, and I'd never clean a toy with JUST toy cleaner and use it internally.
It's great for "I'm too tired and will wash the toys in soap and water in the morning" use and great for the handles and cord of the Wahl and the Hitachi, where water might damage the delicate electronics, though.
