Mineral Oil
(Paraffinum Liquidum) 

Paraffinum Liquidum, also known as liquid paraffin or mineral oil, is a commonly used ingredient for skin moisturization and softening. Liquid paraffin has the following characteristics:

Moisturizing effect

Liquid paraffin has excellent moisturizing properties. It forms a thin film on the skin’s surface, reducing water loss and increasing skin hydration. For dry, rough skin, liquid paraffin can help restore the skin’s moisture balance, leaving it feeling smoother and more hydrated.

Skin barrier protection

As liquid paraffin forms a protective film on the skin’s surface, it provides an additional barrier function, protecting the skin from external environmental threats. This film helps prevent water evaporation and bacteria intrusion, contributing to maintaining healthy skin.


Due to its smooth and slippery texture, liquid paraffin is often added to cosmetics and personal care products to enhance their softness. It enables products to be evenly distributed on the skin and easily spread, while improving the overall texture and feel of the product.

Safety for sensitive skin

Liquid paraffin is widely used in cosmetics and skincare products and is considered relatively gentle and non-allergenic. However, individual skin types and sensitivities may vary, so it is recommended to perform a patch test before using any products containing liquid paraffin to ensure there are no adverse reactions or allergies.


It’s important to note that everyone’s reaction to these ingredients may vary. It is recommended to perform a patch test on a small area of skin before using any new product to ensure there are no adverse reactions.
