Bicarbonate Ion Care Bath Tablets - 100 Tablets These bicarbonate ion care bath tablets are gentle on the delicate skin and coat of pets. They do not use synthetic detergents or surfactants and remove oily sweat and mineral deposits that cause odors on the coat and paws. The skin has a three-layer structure: "epidermis," "dermis," and "subcutaneous tissue." The human epidermis has 10-15 layers, but dogs and cats have only about 2-3 layers, and their thickness is only about 1/3 of that of humans. Therefore, although covered with fur, they are prone to skin problems. Also, unlike humans, dogs have slightly alkaline skin with a pH of 7.2-9.0, and cats have a pH of 6.8-8.5. To avoid problems caused by excessive irritation from acidic shampoos, which can damage the epidermal sebum film and keratinocytes, grooming tabs with a neutral pH that remove chlorine, promote blood circulation, improve metabolism, and promote relaxation are perfect.
