Glyceryl Hydroxystearate is a versatile off-white waxy solid primarily employed as an auxiliary emulsifier in personal care products, closely resembling the properties of beeswax. With an HLB value of 3.4, it significantly enhances emulsion stability, adds body, thickens formulations, and improves emollience while facilitating the dispersibility of colorants and active ingredients. This ester is particularly advantageous for formulations requiring robust emulsification and is widely utilized in products where the dispersibility of active principles is desired, including antiperspirant sticks and roll-ons, shampoos, conditioners, creams, lotions, lipsticks, and hand care items. Typically incorporated at concentrations ranging from 2% to 20%, Glyceryl Hydroxystearate is an essential component for ensuring stability, emollience, and overall formulation quality.
What are the benefits and advantages of using Glyceryl Hydroxystearate in formulations?
Glyceryl Hydroxystearate offers several benefits for cosmetic and skincare formulations. It significantly improves emulsion stability across a wide pH range, ensuring consistent performance and product integrity. Additionally, it enhances emollience, imparting a silky feel to the skin without leaving a greasy residue. Glyceryl Hydroxystearate also enhances the bodying properties of formulations, contributing to a desirable texture and consistency.
How does Glyceryl Hydroxystearate improve formulations containing colorants and active principles?
Glyceryl Hydroxystearate improves the dispersibility of colorants and active principles within formulations, ensuring even distribution and uniform appearance. This property makes it an excellent choice for use in cosmetics where consistent color and ingredient effectiveness are critical. By enhancing dispersibility, it also contributes to the formulation's overall stability and performance.
What makes Glyceryl Hydroxystearate suitable for use in stick preparations?
Glyceryl Hydroxystearate enhances the "pay-off" in stick preparations, such as lipsticks or deodorant sticks, ensuring smooth and even application. Its good solubility in silicone fluids and broad compatibility with most natural and synthetic derivatives make it an ideal choice for stick formulations, providing a balance between efficacy and aesthetic appeal.
Is Glyceryl Hydroxystearate compatible with various formulation components?
Yes, Glyceryl Hydroxystearate exhibits broad compatibility with most natural and synthetic derivatives, making it a versatile ingredient in cosmetic and skincare formulations. Its compatibility allows it to be incorporated into a wide range of products without adversely affecting other ingredient functions or stability.
Can Glyceryl Hydroxystearate be used in formulations with a broad pH range?
Glyceryl Hydroxystearate is suitable for use in formulations with a wide pH range, which enhances its flexibility and application across different product types. Its ability to maintain emulsion stability over a broad pH spectrum is a key advantage for formulators seeking to create stable and effective products.
