What Is Disodium Wheat Germamido Peg-2 Sulfosuccinate?
Disodium Wheat Germamido Peg-2 Sulfosuccinate is a plant based surfactant made from wheat germ oil that has been reacted with a small amount of ethylene oxide, then linked to a sulfosuccinate group and neutralized with sodium. The result is a water loving powder or liquid that mixes easily into formulas. Because the base oil comes from wheat germ it carries natural fatty acids that help soften skin while the sulfosuccinate part delivers cleansing power.
The first sulfosuccinate cleansers showed up in the 1950s as a gentler alternative to traditional soaps. Over time chemists blended them with natural oils to get surfactants that clean without stripping. The wheat germ version gained popularity in the early 2000s when brands started looking for plant sourced ingredients that could still create a rich lather.
Manufacturing starts with cold pressed wheat germ oil. The oil is split into fatty acid chains then attached to a short two unit polyethylene glycol (PEG-2). This PEG-fatty acid is reacted with maleic anhydride to form a succinic backbone, sulfonated to add the cleansing group, then neutralized with sodium carbonate to give the final disodium salt. The process is carried out in closed reactors and finished with filtration and drying to meet cosmetic grade standards.
You will most often find Disodium Wheat Germamido Peg-2 Sulfosuccinate in daily face cleansers, micellar waters, shower gels, sulfate free shampoos, bubble baths, sheet mask essences and baby washes where a mild yet foamy clean is needed.
Disodium Wheat Germamido Peg-2 Sulfosuccinate’s Cosmetic Benefits/Uses
This multi tasking ingredient improves both how a product works and how it feels during use.
- Cleansing – lifts dirt oil sunscreen and light makeup from skin or hair then rinses away with water leaving a fresh yet non tight feel
- Foam Boosting – increases the amount and stability of lather so the wash feels rich and spreads easily even in hard water
- Hydrotrope – helps keep fragrance oils pigments and other hard to dissolve additives evenly dispersed which lets formulators lower the total surfactant load and still keep the product clear
Who Can Use Disodium Wheat Germamido Peg-2 Sulfosuccinate
This gentle surfactant suits most skin and hair types including dry, normal, combination and oily because it cleans without stripping away natural moisture. Sensitive skin usually tolerates it well thanks to its lower irritation profile compared with harsher sulfates. People with very dry or compromised skin may even find it comforting due to the fatty acids from wheat germ oil that leave a light conditioning feel.
Because it is derived from plant based wheat germ oil with no animal by-products it is suitable for both vegetarians and vegans. Those with a diagnosed wheat or gluten allergy should check with their physician before using since trace proteins could remain even though the ingredient is highly processed and the risk is low.

Comedogenic Rating
Rating: 1/5
The wheat germ oil is transformed into a water soluble surfactant that rinses off completely rather than sitting on skin, so it shows very little pore clogging potential.
Generally suitable for acne prone skin.
No data suggest it promotes fungal acne and it is unlikely to accumulate on the skin surface.
Summary
Disodium Wheat Germamido Peg-2 Sulfosuccinate works as a cleanser foam booster and hydrotrope. Its sulfosuccinate head binds to water while the modified wheat germ tail loosens oils, letting grime wash away easily. The short PEG link keeps the molecule mild and helps dissolve fragrances and pigments so formulas stay clear and stable.
You will see it mostly in sulfate free facial washes, shower gels and baby shampoos, but it remains a niche choice compared with classic sulfates, valued by brands that want plant sourced mildness with a rich lather.
Studies and long term market use show it to be low risk for irritation and toxicity in rinse off products. Even so, patch test any new product that contains it to ensure it agrees with your individual skin.
