What Is PEG-75 Shea Butter Glycerides?

PEG-75 Shea Butter Glycerides is a modified form of shea butter that has been treated with polyethylene glycol (PEG) to make it water-soluble. This transformation allows the ingredient to function as an emulsifier—a substance that helps oil and water-based ingredients blend together smoothly in skincare products.

The ingredient originates from shea butter, a traditional moisturising fat derived from shea tree nuts. In its PEG-modified form, it retains some of shea butter's conditioning properties while gaining the ability to stabilise product textures and improve spreadability.

How It Works

PEG-75 Shea Butter Glycerides works by positioning itself between oil and water molecules. One part of the molecule is attracted to oils whilst another is attracted to water, allowing these normally separate components to mix evenly. This prevents separation and creates a stable, uniform product texture.

In addition to this emulsifying function, the ingredient contributes mild moisturising and softening effects inherited from its shea butter origin, though these are secondary to its primary role in formulation stability.

Clinical Evidence & References

Published clinical research specifically examining PEG-75 Shea Butter Glycerides is limited. Most evidence for its efficacy comes from industry testing and formulation science rather than peer-reviewed studies in human subjects.

As an established emulsifier with a long history of use in cosmetics, it is generally regarded as safe and effective for its intended purpose of stabilising products. However, its individual contribution to skin benefits—beyond enabling better product texture—has not been extensively documented in controlled trials.

How to Use

This ingredient is used by formulators rather than consumers; you will not apply it directly. You may encounter it in creams, lotions, serums and other emulsified products. Use products containing this ingredient as directed by the manufacturer, typically daily or as part of your regular skincare routine. There is no need to adjust frequency based on this ingredient alone.

Safety & Precautions

PEG-75 Shea Butter Glycerides is generally well-tolerated and has a long track record of safe use in cosmetics. Some individuals with sensitivities to emulsifiers or PEG-derived ingredients may experience mild irritation, though this is uncommon.
