Propylene glycol (PG) is a colorless and odorless liquid. It is used as a moisturizer, preservative, solvent or emollient in many formulations, such as creams, lotions, face serums, shampoos and many other types of personal care products.
 
As we age, our skin loses an ingredient called Natural Moisturizing Factor (NMF), and then the skin becomes dry and wrinkled. Propylene glycol can combine with water in the environment and helps fight water loss caused by aging.
 
In cosmetics, the content of propylene glycol is generally about 1% to 10%. It is a small molecule moisturizing ingredient, which can retain moisture in the stratum corneum, and is often used in toners and essences.
 
In addition to moisturizing ability, propylene glycol can also help the penetration of active ingredients, and also has antiseptic ability.
 
In makeup remover, propylene glycol can help dissolve dirt and prevent the skin from drying too quickly during makeup removal.
 
As a solvent, propylene glycol can dissolve salicylic acid, ferulic acid, allantoin and vitamin C into the product. This is beneficial for ingredients that are difficult to dissolve in creams and serums, such as fragrances and pigments.
