What Is Peg-20 Hydrogenated Dimer Dilinoleate?
Peg-20 Hydrogenated Dimer Dilinoleate is a plant-derived ingredient created by linking polyethylene glycol to hydrogenated dimer dilinoleic acid, giving it 20 repeating ethylene oxide units. The fatty acid portion usually starts with linoleic acid taken from sources like soybean or sunflower oil. Two linoleic molecules are joined to form a “dimer,” then hydrogenated to make the chain more stable. Finally the dimer is reacted with ethylene oxide to add the water-loving PEG segments, producing a molecule that can mix oil and water with ease.
Chemists began exploring this type of PEG-modified fatty acid in the late 20th century while looking for gentler alternatives to traditional soaps and detergents. Its balanced oil-and-water structure made it an instant fit for modern skincare formulas aiming for mildness plus performance. Over the years it has moved from niche laboratory use into mainstream personal care thanks to its versatility and safety record.
Today you will spot Peg-20 Hydrogenated Dimer Dilinoleate in a range of products such as cleansing balms, creamy face washes, makeup removers, micellar waters, hydrating masks, lightweight moisturizers, hair conditioners and even some baby care items. Its ability to dissolve makeup, mix oil with water and leave skin feeling soft is why formulators keep reaching for it.
Peg-20 Hydrogenated Dimer Dilinoleate’s Cosmetic Benefits/Uses
This ingredient pulls double duty in many formulations, helping products work better while feeling pleasant on skin.
- Cleansing: Its amphiphilic structure loosens and lifts away dirt, excess oil and makeup without stripping the skin’s natural barrier, giving a gentle yet effective clean.
- Emulsifying: It binds oil and water into a stable mixture, preventing separation in creams, lotions and balms, which means a smoother texture and consistent performance every time you use the product.
Who Can Use Peg-20 Hydrogenated Dimer Dilinoleate
This ingredient is generally well tolerated by all skin types including dry, oily, combination and sensitive skin because it cleanses without harsh surfactants and leaves a light, non greasy finish. People with a known sensitivity to polyethylene glycols or fatty acid derivatives should proceed with caution.
The raw materials come from plant oils and petrochemical ethylene oxide, with no animal by-products involved. That makes Peg-20 Hydrogenated Dimer Dilinoleate suitable for vegans and vegetarians, provided the finished product is not tested on animals and the brand meets individual ethical standards.
Current safety data show no reproductive or developmental concerns, so products containing this ingredient are considered safe for women who are pregnant or breastfeeding. This is not medical advice and anyone expecting or nursing should still share their full skincare routine with a qualified healthcare provider.
Peg-20 Hydrogenated Dimer Dilinoleate does not cause photosensitivity, so it will not make skin more prone to sunburn. Users should simply follow normal sun protection habits.
Because it is mild and non occlusive, it is often found in baby care and scalp products as well. Always follow the specific directions and age recommendations given by the manufacturer.
Potential Side Effects/Adverse Reactions
Everyone’s skin is different, so reactions to topical Peg-20 Hydrogenated Dimer Dilinoleate can vary. The points below outline potential side effects, yet most people will not experience them when the ingredient is used at standard levels in a well formulated product.
- Mild redness or stinging especially on freshly exfoliated or compromised skin
- Dryness if the formula pairs it with strong solvents or high alcohol content
- Allergic contact dermatitis in rare cases where an individual is sensitive to polyethylene glycols
- Eye irritation if a cleansing oil or balm is not fully rinsed from the eye area
If you notice any discomfort discontinue use and consult a dermatologist or healthcare professional
Comedogenic Rating
Rating: 1/5
Peg-20 Hydrogenated Dimer Dilinoleate contains a fatty backbone, yet the addition of 20 PEG units turns it into a mostly water-soluble molecule that rinses away cleanly. It does not sit on skin like heavier oils, so it has little chance of clogging pores. Its rating is therefore low at 1.
That makes it generally suitable for acne-prone or breakout-prone skin, provided the overall formula is light and non-occlusive.
Keep in mind that comedogenicity can rise if the ingredient is blended with waxes or rich oils, so the finished product still matters.
Summary
Peg-20 Hydrogenated Dimer Dilinoleate works as a gentle cleanser and reliable emulsifier. Its fatty portion grabs onto oils and makeup while the PEG side bonds with water, allowing grime to lift away and keeping creams uniformly mixed.
Although it is not as famous as classic surfactants like sodium lauryl sulfate, its mildness has earned it steady use in cleansing balms, micellar waters and baby care where a softer touch is valued.
Current research and widespread usage show it to be low risk for irritation or long-term harm when used at normal cosmetic levels. As with any new product, give your skin a bit of caution and do a quick patch test before full use.
