Hydrogenated Soy Glyceride
INCI: Hydrogenated Soy Glyceride
A gentle, plant-derived emollient that softens skin without clogging pores, ideal for dry or sensitive skin.
In plain English
Hydrogenated Soy Glyceride is a modified form of soybean oil that has been turned into a stable, semi-solid fat. In skincare, it works as an emollient, meaning it fills in the tiny gaps between skin cells to make the surface feel smoother and softer. It also helps other ingredients spread evenly and keeps moisture from evaporating. Because it's hydrogenated, it's less likely to go rancid than plain soybean oil, and it's generally very gentle on the skin.

Quick decision guide
Easy yes for most routines
Hydrogenated Soy Glyceride is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Hydrogenated Soy Glyceride.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic ingredient made by hydrogenating (adding hydrogen to) soybean oil glycerides, turning liquid oil into a stable, waxy solid that feels smooth on the skin.
How it works
It sits on the skin's surface, forming a thin, non-greasy film that reduces water loss and makes the skin feel soft and supple. It also helps blend oil- and water-based ingredients in a formula, improving texture and spreadability.
Pros
Gentle on sensitive skin
Hydrogenated Soy Glyceride has a very low irritation potential, making it suitable for even reactive or eczema-prone skin types.
Non-comedogenic
Unlike some heavier oils, this ingredient is unlikely to clog pores, so it can be used by those prone to breakouts without fear of congestion.
Cons and cautions
May feel heavy on oily skin
While non-comedogenic, its emollient nature can feel slightly rich or greasy for people with very oily skin, especially in humid climates.
Soy allergen concern
Because it is derived from soy, individuals with a soy allergy may experience a reaction, though the hydrogenation process reduces protein content significantly.
Best for
- People with dry or dehydrated skin looking for a gentle emollient
- Those with sensitive or easily irritated skin who want a non-irritating moisturizer
Use caution if
- Individuals with a known soy allergy should patch test first
Usage tips
Safety summary
Hydrogenated Soy Glyceride is considered very safe for topical use. It has low irritation and sensitization potential, and no significant toxicity concerns have been reported in cosmetic concentrations.
Research notes
While specific studies on Hydrogenated Soy Glyceride are limited, the safety of hydrogenated vegetable glycerides as a class is well-established by the Cosmetic Ingredient Review panel. Its emollient and skin-conditioning properties are supported by general knowledge of fatty acid chemistry.
Common label clues
- Typical concentration
- 0.5% to 5% in leave-on products
- Regulatory status
- Approved as a safe cosmetic ingredient by the Cosmetic Ingredient Review (CIR) panel and widely used globally.
- Common uses
- Moisturizers, Creams, Lotions, Lip balms, Bar soaps
- Environmental note
- Soy is a renewable resource, but large-scale cultivation can be associated with deforestation and pesticide use. Look for sustainably sourced or organic soy if this is a concern.
Good to know
- Hydrogenation makes the ingredient more stable and less prone to oxidation than regular soybean oil.
- It is often used in bar soaps to improve lather creaminess and skin feel.
