[Chemical Knowledge]:Propylene Glycol and Ethylene Glycol: The Two Main Ingredients in Cosmetics

Propylene glycol and ethylene glycol are two main ingredients commonly used in cosmetics, both of which have the effects of moisturizing, penetrating and stabilizing formulations. But the application and effect in cosmetics are different.

we look at propylene glycol. Propylene glycol is a very common thickener and moisturizer, which can provide sufficient moisture to the skin and prevent skin dryness and dehydration. At the same time, propylene glycol can also help other active ingredients to better penetrate into the skin lining, enhance the efficacy of skin care products. Moreover, propylene glycol is less irritating to the skin and is suitable for people with various skin types.

followed by ethylene glycol. Ethylene glycol, like propylene glycol, is also a good humectant, but it is more used for cosmetic formulation stability. Ethylene glycol can help maintain the texture and taste of cosmetics and prevent cosmetics from delaminating or dehydrating after prolonged use. Ethylene glycol is also a good solvent, which can help other ingredients to dissolve and mix better, and improve the stability of cosmetic formulations.

Although propylene glycol and ethylene glycol are both good humectants, their application in cosmetics is also different due to their different characteristics. In general, propylene glycol is more commonly used in skin care products and creams to provide adequate moisture and nutrition to the skin. Ethylene glycol is more used in emulsions and serum to maintain the stability and texture of cosmetics.

In general, propylene glycol and ethylene glycol are both indispensable and important ingredients in cosmetics. Each of them has a unique role and can provide more possibilities and choices for skin care products. Therefore, when choosing cosmetics, you can choose products containing propylene glycol or ethylene glycol according to your skin type and needs to achieve better skin care effects.
