What Is Soybean Oil Polyglyceryl-6 Esters?
Soybean Oil Polyglyceryl-6 Esters is a plant derived ingredient created by joining soybean oil with polyglycerin-6 through a process called transesterification. The result is a mild, multifunctional compound that marries the nourishment of soybean lipids with the water friendly character of glycerin chains. Soybeans have been pressed for their oil for centuries, yet it was only in recent decades that chemists began modifying the oil to improve its performance in modern skin care. By reacting the oil with polyglycerin-6, they produced an ester that disperses easily in both water and oil phases, a quality that makes formulating smoother and more stable.
The production starts with food grade Glycine Soja oil that is purified then blended with polyglycerin-6 under heat and an alkaline catalyst. Fatty acid portions of the oil swap places with glycerin units, creating a new molecule that offers better spreadability and self emulsifying power. After neutralization and filtration the ester is refined into a soft, pale liquid ready for cosmetic use.
Thanks to its gentle nature and versatility, Soybean Oil Polyglyceryl-6 Esters appears in a wide range of products such as facial cleansers, micellar waters, hydrating toners, lightweight moisturizers, nourishing masks, baby care lotions, scalp treatments and makeup removers. Formulators value it for giving a silky finish without heaviness and for helping oil and water based ingredients stay blended over time.

This is not medical advice; expecting or nursing parents should always review new skincare products with a qualified healthcare professional before adding them to a routine.

Comedogenic Rating
Rating: 1 / 5
The bulky glycerin rich structure of Soybean Oil Polyglyceryl-6 Esters is far more water friendly than plain soybean oil so it spreads thinly and rinses off rather than settling in pores. That chemistry lowers its clogging potential and earns it a low score of 1.
Most people prone to acne can use products containing this ester without extra concern but those extremely sensitive to any oil derived material may still prefer spot applications first.
Its mild profile also allows formulators to pair it with heavier occlusives without dramatically raising the overall comedogenic footprint of a formula.
