What Is Peg-50 Hydrogenated Castor Oil Laurate?
Peg-50 Hydrogenated Castor Oil Laurate is a plant-derived ingredient that starts with traditional castor oil pressed from the seeds of the Ricinus communis plant. The raw oil is first hydrogenated, a process that saturates its fatty acids to make it solid and more stable. It is then reacted with ethylene oxide about fifty times on average, creating a water-friendly polyethylene glycol (PEG) chain, and finally esterified with lauric acid from coconut or palm sources. The result is a waxy, semi-solid substance that acts as a bridge between oil and water in cosmetic formulas.
Hydrogenated castor derivatives have been used since the mid-20th century when formulators looked for plant oils that could be modified to disperse in water without losing their softness. By adding PEG chains and lauric acid, chemists created a skin-friendly material that blends effortlessly into creams and lotions.
Today Peg-50 Hydrogenated Castor Oil Laurate shows up in a wide range of products such as facial moisturizers, serums, sheet masks, cleansing balms, makeup removers, sunscreens, hair conditioners and soothing after-sun gels. Its ability to marry oil-soluble nutrients with water-based formulas makes it a quiet workhorse in modern personal care.
Peg-50 Hydrogenated Castor Oil Laurate’s Cosmetic Benefits/Uses
This ingredient is valued primarily for one key role in skincare.
Skin conditioning: Peg-50 Hydrogenated Castor Oil Laurate coats the skin with a light, breathable layer that traps moisture and leaves the surface feeling soft and smooth. By improving spreadability it helps creams glide on evenly, boosts the delivery of other actives and keeps the finish comfortable rather than greasy.
Who Can Use Peg-50 Hydrogenated Castor Oil Laurate
This ingredient is gentle enough for most skin types including normal, dry, combination and even sensitive complexions thanks to its lightweight, non-greasy feel. Very oily or highly acne-prone skin could find rich formulas that contain a lot of it a touch too occlusive, so checking the overall product texture is wise.
Peg-50 Hydrogenated Castor Oil Laurate is derived from plant oils and synthetic ethylene oxide, with no animal sourced components, making it acceptable for vegans and vegetarians.
Current safety data show no specific risks for women who are pregnant or breastfeeding when the ingredient is used topically at the low levels seen in cosmetics, but this is not medical advice. Anyone expecting or nursing should run their skincare routine past a qualified healthcare provider to be safe.
The ingredient does not increase photosensitivity, so it will not make skin more prone to sunburn. It is also fragrance-free and mineral-oil-free, useful details for people tracking particular sensitivities.

Comedogenic Rating
Rating: 1/5
Peg-50 Hydrogenated Castor Oil Laurate is highly water dispersible and forms a thin flexible film rather than a thick waxy layer. Its large PEG chain keeps it from packing tightly inside pores which lowers the chance of blockages. While pure hydrogenated castor oil can feel heavy the addition of 50 units of ethylene oxide and lauric acid makes this derivative far lighter and easier to rinse off so it earns a low score of 1.
With such a low rating it is generally fine for acne-prone or breakout-prone skin when used in well balanced formulas.
Most products include the ingredient at modest levels as a helper rather than the star which further reduces clogging risk.
Summary
Peg-50 Hydrogenated Castor Oil Laurate conditions skin by laying down a soft moisture binding layer that smooths rough patches and improves slip. Its hybrid oil-in-water nature lets it pull oily nutrients into watery bases so everything spreads evenly and feels light. Because of this dual action it shows up in moisturizers cleansers sunscreens and masks even though few shoppers know it by name.
It is considered low risk for irritation or pore clogging with a solid safety record in topical use. Still it is smart to run a quick patch test whenever adding a new product just to be sure your skin agrees.
