What Is Peg/Ppg-10/2 Diricinoleate?
Peg/Ppg-10/2 Diricinoleate is a lab-crafted ingredient derived from castor oil, a plant oil known for its high content of ricinoleic acid. Chemists react castor oil with ethylene oxide and propylene oxide, attaching an average of ten ethylene oxide units and two propylene oxide units to the fatty acid backbone to create a diester. The end result is a waxy or pasty material that excels at keeping oil and water mixed. Interest in this type of molecule began in the 1970s when formulators searched for milder alternatives to strong detergents. Over the years the ingredient gained popularity for its ability to form stable, creamy textures without leaving a heavy residue. Today it shows up in moisturizers, cleansing balms, face masks, sunscreen lotions, makeup removers and some hair conditioners where a smooth spread and consistent feel are essential.
Peg/Ppg-10/2 Diricinoleate’s Cosmetic Benefits/Uses
Its main role in a formula is as an emulsifier, meaning it binds oil and water together so the product stays uniform from the first use to the last. By stabilizing emulsions it prevents separation, improves texture, enhances the delivery of active ingredients and gives products a pleasing, non-greasy finish.
Who Can Use Peg/Ppg-10/2 Diricinoleate
This emulsifier is generally well tolerated by most skin types including normal, dry, combination and oily. Its lightweight finish means it will not feel heavy on oilier skin while its ability to lock water and oil together can help dry or flaky complexions feel smoother. Sensitive skin usually does fine with it because it has a low risk of stinging or disruption to the skin barrier, though anyone with a proven allergy to castor oil derivatives should approach with care.
Peg/Ppg-10/2 Diricinoleate is sourced from plant-based castor oil and is synthesized without any animal-derived components, so it is suitable for vegans and vegetarians.
No specific warnings exist for pregnant or breastfeeding women when this ingredient appears in rinse-off or leave-on products at typical amounts. It is considered low risk for systemic absorption. Still, this is not medical advice; anyone who is pregnant or nursing should discuss all skincare products with a qualified health professional to be safe.
The ingredient does not make skin more sensitive to sunlight, so there is no added risk of photosensitivity.
It plays well with most other cosmetic ingredients and does not interfere with common actives like retinoids, vitamin C or exfoliating acids.
Potential Side Effects/Adverse Reactions
Responses to topical Peg/Ppg-10/2 Diricinoleate differ from person to person. The issues below are possible but not common when the ingredient is used at standard levels by reputable brands.
Minor redness or itching in people who are sensitive to castor oil derivatives
Mild eye irritation if the product accidentally gets into the eyes
Rare allergic contact dermatitis leading to swelling or rash
If any of these reactions occur stop using the product and consult a healthcare professional.
Comedogenic Rating
Rating: 1 out of 5. Peg/Ppg-10/2 Diricinoleate comes from castor oil yet its chemical modification strips away most pore-clogging traits. The molecule is partly water soluble and tends to rinse off rather than form a heavy film so buildup inside follicles is unlikely. Brands also use it at modest levels to stabilize formulas instead of as a rich emollient, further lowering the chance of congestion.
With a rating of 1 the ingredient is generally considered suitable for skin that is prone to acne or breakouts.
Real-world pore clogging can still depend on the overall product, usage habits and individual skin chemistry.
Summary
Peg/Ppg-10/2 Diricinoleate acts mainly as an emulsifier that keeps oil and water phases blended, smooths texture and helps other ingredients glide over the skin. Its castor-derived fatty chain loves oil while its polyethylene glycol side loves water, letting it sit at the interface and hold everything together.
It is less well known than staple emulsifiers like glyceryl stearate yet appreciated by formulators who need a plant-based option that delivers a light non-greasy feel, so it shows up quietly in a wide range of creams, balms and sunscreens.
Studies and practical use suggest it has a very low risk of irritation, sensitization or systemic absorption. Even so it is smart to patch test any new product containing this ingredient to make sure your skin stays comfortable.
