diglycerin

Description

Diglycerin is a versatile and effective humectant used in various skincare and cosmetic formulations. This clear, colorless, and odorless liquid is derived from glycerin, a well-known moisturizing agent. Diglycerin's molecular structure consists of two glycerin molecules bonded together, resulting in enhanced hygroscopic properties compared to its precursor.

As a potent moisture-binding ingredient, diglycerin attracts and retains water from the atmosphere and deeper skin layers, helping to maintain optimal hydration levels in the stratum corneum. Its low molecular weight allows for easy penetration into the skin, providing long-lasting moisturization without a greasy or sticky feel.

Diglycerin exhibits excellent compatibility with other cosmetic ingredients and demonstrates stability across a wide pH range. It functions as an effective solvent for active ingredients and contributes to the overall texture and sensory qualities of skincare products. Additionally, diglycerin has been shown to enhance the efficacy of preservatives, potentially allowing for reduced concentrations of these additives in formulations.

This ingredient is particularly beneficial in products designed for dry or dehydrated skin, as well as in anti-aging formulations where maintaining skin hydration is crucial for improving the appearance of fine lines and wrinkles.
