Soybean Oil: Benefits & Uses
A soybean-derived emollient oil that helps skin feel soft, supple and comfortably conditioned.
What it is
Soybean oil is a plant-derived oil obtained from the seeds of Glycine max. On cosmetic labels, it may appear as Glycine Max (Soybean) Oil or the older equivalent name Glycine Soja (Soybean) Oil. It is a fixed vegetable oil made largely of fatty acids, including linoleic and oleic acids.
This identity is specifically the oil—not soybean extract, soybean ferment, soybean protein, sterols, hydrogenated soybean oil, or soybean oil unsaponifiables. Those are separate cosmetic ingredients with different compositions.
Why shoppers choose it
In a cleansing oil, soybean oil contributes several practical qualities:
- Helps lift oil-soluble residue: As part of the finished cleanser, it helps loosen makeup, sunscreen, excess sebum, and other oily buildup so they can be rinsed away.
- Provides comfortable slip: The oil helps the cleanser glide across dry skin, reducing the need for vigorous rubbing.
- Conditions and softens: Its emollient character can leave skin feeling smoother and less stripped after cleansing.
- Complements a moisturizing finish: Its fatty-acid-rich profile makes it useful in cleansers designed for a softer rather than squeaky-clean after-feel.
These qualities describe its role within a complete formula. The cleansing and rinse-off experience also depends on the product’s emulsifiers and other oils.
How to use it
Use the Gentle Black Deep Cleansing Oil as directed for the finished product. Dispense it onto dry hands and gently massage it over a dry face, including areas with makeup or sunscreen. Avoid aggressive rubbing around the eyes.
Add a little lukewarm water and continue massaging briefly so the cleanser can emulsify, then rinse thoroughly. Follow with a water-based cleanser if you prefer double cleansing or if residue remains. How often you use it can depend on your makeup, sunscreen, skin type, and preferred cleansing finish.
Common questions
Is soybean oil the same as soybean extract? No. The oil is the lipid-rich material obtained from soybean seeds. Extracts and ferments are distinct ingredients and should not be treated as interchangeable.
Are Glycine max oil and Glycine soja oil the same identity? For this ingredient, regulatory identity records list Glycine Max (Soybean) Oil and Glycine Soja (Soybean) Oil as names for soybean oil.
Will soybean oil make a cleansing oil feel greasy? Not necessarily. The complete formula determines texture and rinse-off. Cleansing oils contain emulsifiers that help the oils mix with water and wash away.
Can oily skin use a cleanser containing it? Skin type alone does not determine whether a cleansing oil will suit you. Massage gently, emulsify well, rinse thoroughly, and judge the finished product by how your skin feels afterward.
