PEG-150 Distearate serves as an effective non-ionic thickener and emulsifier, produced through the esterification process involving polyethylene glycol and stearic acid. With an HLB value of 18.9, it functions efficiently as both a primary and auxiliary emulsifier in products like body washes, conditioners, lotions, creams, and shampoos. Typically, it is incorporated into the oil or surfactant phase and heated to temperatures between 80-85°C (176-185°F). Owing to its high molecular weight, PEG-150 Distearate also acts as a viscosity modifier, opacifying agent, and conditioning agent, particularly in hair and skincare formulations. When used in combination with PEG-80 Sorbitan Laurate, it provides an excellent base for shampoos formulated with amphoteric surfactants. Available in solid form as white flakes, it is generally used in concentrations ranging from 0.2% to 2.0% and is known for being non-irritating to both eyes and skin, which makes it suitable for baby care products. Additionally, it complies with the Orthodox Union (OU) Kosher certification standards.

PEG-150 distearate is a diester of stearic acid with a degree of polymerization of 150 ethylene oxide repeating units; both stereoends exhibit surface and interfacial activity, enabling physical crosslinking between micelles. This significantly improves the resilience of the system.
To investigate the self-healing behavior of polyethylene glycol-150 distearate (PEG) combined with PVA, a self-healing composite prepared by freeze-thaw method using PVA and PEG-150 distearate was developed and evaluated. Repair hydrogels have potential applications in tissue engineering.
The developed hydrogels showed higher crystallinity than the control hydrogels (without freeze/thaw cycles). Furthermore, the hydrogel exhibited sufficient chemical and mechanical responsive properties to enable it to maintain its structure when subjected to sudden impact. Furthermore, hydrogels are able to deform at low levels of mechanical stress, making them an excellent choice for tissue engineering materials.

The Society for Hair Testing (SoHT) recommends the use of direct alcohol markers (ethyl glucuronic acid (EtG) and fatty acid ethyl esters (FAEE)) to determine whether a subject has previously consumed alcohol. This article measured whether four cleansing shampoos altered hair EtG or FAEE levels. Shampoo formulation 1 used PEG-150 distearate as an ingredient.
With regard to EtG rinsing, shampoo 1 performed similarly to deionized water, while shampoo 3 performed best. For FAEE, no rinsing effect was observed with detoxifying shampoo 1, while shampoo 2 and shampoo 4 resulted in an increase in measured FAEE concentrations over time. That is, detoxifying shampoos were shown to have the potential to alter EtG and FAEE concentrations in hair in vitro experiments, but dependent on their formulation composition.

What is PEG-150 Distearate and how is it produced?
PEG-150 Distearate is a non-ionic thickener and emulsifier. It is produced through the esterification of polyethylene glycol with stearic acid, resulting in a diester of a 6000 molecular weight polyethylene glycol.
In what types of products can PEG-150 Distearate be used?
This ingredient works well as a primary or auxiliary emulsifier in a variety of personal care products, including body washes, conditioners, lotions, creams, and shampoos.
What is the benefit of adding PEG-150 Distearate to formulations?
PEG-150 Distearate functions as a viscosity modifier, opacifying agent, and conditioning agent in hair and skin care products, enhancing texture and stability.
How should PEG-150 Distearate be incorporated into formulations?
It is added to the oil phase or surfactant phase of a formulation and needs to be heated to 80-85°C (176-185°F) for optimal performance.
What is the recommended usage level of PEG-150 Distearate in formulations?
Typically, PEG-150 Distearate is used at concentrations ranging from 0.2% to 2.0%.
Is PEG-150 Distearate safe for use in baby care products?
Yes, PEG-150 Distearate is not irritating to the eyes or skin, which makes it an ideal ingredient for baby care formulations.
Can PEG-150 Distearate be used with other surfactants in shampoos?
Yes, when combined with PEG-80 Sorbitan Laurate, it can be used to manufacture shampoo bases formulated with amphoteric surfactants.
