Why does bath oil foam? How to make bath oil foam more

Bath oil is a skin care product that is specially added to bath water. Regular bathing with bath oil can help soften and moisturize the skin, eliminating dry and rough patches. So, why do bath oils foam?

Why do bath oils foam?

Bath oil foams because a small amount of surfactant, or foaming agent, is added to it. The foaming agent reduces the interfacial tension at the air-water interface, prompting the air to form small bubbles in the slurry, expanding the separation interface, and ensuring that the bubbles rise to form a foam layer. However, the bath oil produces very few bubbles.

How to make bath oil bubble more

Bath oil has only mild foaming ability, which is also a disadvantage of bath oil compared to shower gel, that is, low foaming or even no foaming. If you want more bubbles, you can use it with a bath ball or shower gel.

The cleansing principle of bath oil

The formula base of shower oil is basically "oil", which can wash away dead skin, sebum and sweat without over-degreasing. It will feel moisturized after rinsing, adding a moisturizing feeling to the skin. The only drawback is low foaming or even no foaming. Different products have different oily textures, and many people may not be able to accept it.

The difference between bath oil and shower gel

Real bath oil is made entirely of oils and very little else is added, whereas most shower gels contain more surfactants and foaming agents, so after taking a bath, your skin will become dry, flaky, itchy and uncomfortable. A good bath oil will have excellent cleansing and moisturizing properties and will not harm the skin.

Bath oils are very expensive, with most being priced mid to high end, while shower gels are generally slightly cheaper. Bath oil is a good skin care product. Long-term use of bath oil can delay skin aging, promote skin absorption function, renew cell metabolism, and maintain the health of human skin; the fatty acids in bath oil can make the skin moisturized and shiny. Choose a mild bath oil that can help repair dryness, itching, and scaling on the skin.
