Propylene glycol and ethylene glycol are two common main ingredients in cosmetics, both of which have moisturizing, penetrating, and stabilizing effects on the formula. But there are differences in the application and function in cosmetics

Let's take a look at propylene glycol. Propylene glycol is a very common thickener and moisturizer that can provide sufficient moisture to the skin, preventing dryness and dehydration. Meanwhile, propylene glycol can also help other active ingredients better penetrate into the inner layer of the skin, enhancing the efficacy of skincare products. Moreover, propylene glycol has low skin irritation and is suitable for use by people of various skin types

Next is ethylene glycol. Ethylene glycol, like propylene glycol, is also a good moisturizer, but it is more commonly used in cosmetic formula stability. Ethylene glycol can help maintain the texture and taste of cosmetics, preventing them from layering or dehydration after prolonged use. Ethylene glycol is also a good solvent that can help other ingredients dissolve and mix better, improving the formula stability of cosmetics

Although propylene glycol and ethylene glycol are both good moisturizers, their application in cosmetics varies due to their different characteristics. Generally speaking, propylene glycol is more used in skin care products and face cream to provide sufficient moisture and nutrition for the skin. Ethylene glycol is more used in lotion and essence to maintain the stability and texture of cosmetics

Overall, propylene glycol and ethylene glycol are essential components in cosmetics. They each have unique roles and can provide more possibilities and choices for skincare products. Therefore, when choosing cosmetics, you can choose products containing propylene glycol or ethylene glycol based on your skin type and needs to achieve better skincare effects.
