What Is Peach Kernel Oil Glycereth-8 Esters?
Peach Kernel Oil Glycereth-8 Esters is a plant-derived ingredient made by joining glycereth-8, a water-binding form of glycerin, with oil pressed from peach kernels. This “transesterification” process creates a new molecule that keeps the nourishing fatty acids of peach oil yet gains the water-friendly nature of glycereth-8. The result is a lightweight, silky liquid that mixes easily with both water and oils.
Peach trees have been cultivated for thousands of years but the cosmetic use of their seed oil rose in the last century when cold-press technology made it easy to extract the mild, vitamin-rich oil. Chemists later combined it with glycereth-8 to boost its solubility, opening the door for broader use in modern formulas.
You’ll spot Peach Kernel Oil Glycereth-8 Esters in facial cleansers, micellar waters, cream washes, gentle baby products, makeup removers, micellar wipes and some light moisturizers where a soft, non-greasy feel is desired. Because it bridges oil and water, it also shows up in watery gels and spray-on lotions that need help keeping every ingredient blended.

Comedogenic Rating
Rating: 1 / 5
Because the glycereth-8 portion makes the peach oil highly water friendly the finished molecule rinses away instead of settling into pores. Its fatty acids are mostly lightweight oleic and linoleic types that skin can use rather than store as clog-causing residue. For these reasons the risk of blocked pores is low.
Suitable for acne-prone or breakout-prone skin in most cases.
Formulas that pair this ingredient with heavy waxes or butters may change the overall pore-clogging potential so check the whole ingredient list when in doubt.
Summary
Peach Kernel Oil Glycereth-8 Esters is valued for one main job: gentle cleansing. The peach oil half dissolves makeup and excess sebum while the glycereth-8 half grabs onto water so grime can be whisked away without stripping skin.
You will mostly see it in mild facial cleansers micellar waters makeup removers and baby washes. It is useful but still a niche choice so it does not appear as often as classic surfactants like coco-glucoside or sodium laureth sulfate.
Current safety data shows a very low risk of irritation or allergy for the average user. As with any new skincare product do a quick patch test first to make sure your skin agrees with it.
