PEG-8 RASPBERRIATE

INCI: PEG-8 RASPBERRIATE | Function: Emollient, Skin Conditioning | Type: Moisturizer

What Is PEG-8 RASPBERRIATE?

A PEG-8 ester of raspberry-derived fatty acids (raspberry seed oil is rich in linoleic acid, alpha-linolenic acid, and ellagic acid). This water-dispersible emollient combines the skin-conditioning and antioxidant benefits of raspberry seed oil with the water compatibility of the PEG chain. It provides lightweight moisturization, antioxidant protection, and a pleasant sensory profile.

Key Skin Benefits

+ Raspberry-derived antioxidants — ellagic acid and tocopherols provide free radical protection
+ Essential fatty acid delivery — linoleic and alpha-linolenic acids support skin barrier
+ Lightweight moisturization — conditions without greasy feel
+ Water-dispersible — enables raspberry oil benefits in water-based formulas

Pros

+ Plant-derived — raspberry seed oil is a renewable, upcycled byproduct of the fruit industry
+ Natural antioxidant content — ellagic acid is a potent polyphenol with documented skin benefits
+ CIR-reviewed — PEG fatty acid esters considered safe
+ Non-comedogenic — suitable for facial products
+ Multi-functional — combines emolliency, antioxidant, and barrier support

Cons

− PEG content — ethoxylation introduces trace contaminant risk
− Limited specific clinical data on PEG-8 Raspberriate itself
− Raspberry seed oil content may vary by source and extraction method
− Potential for oxidation — fatty acids require proper preservation
