PEG-150 Distearate is an ester formed upon a combination of PEG (Polyethelene glycol) and stearic acid. It is used in cosmetics and personal care products as an emulsifier, stabilizer, and thickener. It is also used in some industrial applications. PEG-150 Distearate has been associated with some concerns, including non-reproductive organ system toxicity and contamination concerns. It can contain harmful impurities, including Ethylene Oxide, which is known to increase the incidences of uterine and breast cancers and of leukemia and brain cancer. It is also known as PEG-6000 Distearate.
Acts as an emulsifier, stabilizer, and thickener in cosmetic and personal care products. It helps to increase the thickness of the product and enhances its overall performance on the skin. It also functions as a surfactant and forms the base of many cleansing products.
Oily skin
Minimal ocular irritation is seen with PEGs, PEG Stearates, Steareths and Stearic Acid. No evidence of mutagenicity, carcinogenicity, or reproductive and developmental toxicity of these related compounds was found.
Cosmetic manufacturers should continue to adjust product formulations to minimize any untoward effects for products intended to be used on damaged skin.
PEG-150 distearate is derived from stearic acid, a naturally occurring fatty acid found in palm kernel oil.
Safe for use in cosmetic formulations.

PEG Distearate ingredients are the polyethylene glycol diesters of stearic acid. In cosmetics and personal care products, PEG Distearates are used as surfactants (emulsifying agents, cleansing agents, and solubilizing agents). PEG-150 Distearate is also known as PEG-6000 Distearate. It is a non-ionic surfactant and emulsifier that is used in a variety of personal care products, including shampoos, conditioners, and lotions. PEG-6000 Distearate is also used in some industrial applications, such as metalworking and textile manufacturing. PEG-150 distearate is mainly used as a micellar thickening agent for surfactant-based cleansers, especially shampoos, shower gels and face washes. It can also be used as a nonionic emulsifier for o/w systems. In addition, the use of PEG-150 distearate in color cosmetics, hair conditioner and shaving preparations has been reported in the literature. Small amounts of 1,4-dioxane, a by-product of ethoxylation, may be found in PEG-Distearate ingredients. The potential presence of this material is well known and can be controlled through purification steps to remove it from the ingredients before blending into cosmetic formulations. PEG 150 Distearate is a chemical hair thickener that can be replaced with Castor oil or Olive oil. Pyunkang Yul Moisture Ampoule contains PEG-150 Distearate as one of its ingredients. The product is designed to soothe and calm the skin while giving it a plump, bouncy texture. It is suitable for oily skin types. However, the reviewer found that the product was not hydrating enough for her dry skin and she needed to top it up with an oil or cream. She also mentioned that the product has a viscous texture that is not easy to apply on dry skin.
