Product Overview

Glycol Distearate, a diester of stearic acid with ethylene glycol, serves as a versatile component in various cosmetic and personal care formulations. Its primary functions include acting as an emulsifier with an HLB value of approximately 5.5, stabilizing emulsions, and providing opacity. In creams and lotions, it enhances texture by serving as an emollient and viscosity builder, while in surfactant systems, it contributes to the opacifying and pearlizing effects. Typically incorporated at concentrations ranging from 0.5% to 4%, Glycol Distearate is valued for its ability to improve product aesthetics and performance.

Custom Q&A

What is Glycol Distearate, and what are its primary functions?

Glycol Distearate is a diester of stearic acid combined with ethylene glycol. It is a waxy solid frequently utilized in cosmetic and personal care products for its properties as an emulsifier, emulsion stabilizer, and opacifier. Additionally, it acts as an emollient and viscosity builder in creams and lotions and serves as an opacifying and pearlizing agent in surfactant systems.

What is the typical usage concentration of Glycol Distearate in formulations?

Glycol Distearate is typically used at concentrations ranging from 0.5% to 4% in formulations. The specific concentration can vary based on the desired effects and the type of product in which it is being used.

How does Glycol Distearate function in creams and lotions?

In creams and lotions, Glycol Distearate acts as an emollient and viscosity builder. It helps to enhance the texture and feel of these formulations, making them smooth and easily spreadable. Its ability to stabilize emulsions also ensures that the ingredients remain well-mixed and effective throughout the shelf life of the product.

What role does Glycol Distearate play in surfactant systems?

Within surfactant systems, Glycol Distearate serves as an opacifying and pearlizing agent. This means it can add a visually appealing, pearlescent sheen to products such as shampoos and body washes, while also helping to modify the transparency and appearance of the formulation.

What is the HLB value of Glycol Distearate, and why is it important?

Glycol Distearate has a Hydrophilic-Lipophilic Balance (HLB) value of approximately 5.5. This value is crucial as it helps formulators understand the emulsifying capability of Glycol Distearate, indicating its preference for creating water-in-oil emulsions and its compatibility with various other ingredients in complex formulations.
