What Is Dihydrocholesteryl Butyrate?
Dihydrocholesteryl Butyrate is an ester formed by linking dihydrocholesterol, a hydrogenated form of cholesterol, with butyric acid. The starting cholesterol is most often sourced from wool grease or from plant sterols that are chemically converted, giving manufacturers flexibility to meet both conventional and vegan product needs. First introduced to personal care labs in the late 1970s, the ingredient offered formulators a way to mimic the softening effect of natural skin lipids without the heaviness of raw cholesterol itself. Production involves purifying cholesterol, hydrogenating it to create dihydrocholesterol, then esterifying it with butyric acid in a controlled reaction that yields a stable, wax-like substance. Thanks to its silky feel and skin affinity, Dihydrocholesteryl Butyrate shows up in moisturizers, night creams, anti-aging serums, lipsticks, balms, hair conditioners and rich facial masks where a smooth spread and cushiony afterfeel are desired.
Dihydrocholesteryl Butyrate’s Cosmetic Benefits/Uses
This ingredient pulls double duty in many formulations
- Skin conditioning: It helps replenish surface lipids, supporting a smoother, softer complexion and enhancing the overall look of healthy skin.
- Emollient: Its wax-like texture forms a light, breathable layer that traps moisture, reduces transepidermal water loss and leaves skin feeling nourished rather than greasy.
Who Can Use Dihydrocholesteryl Butyrate
Dihydrocholesteryl Butyrate is generally well tolerated by most skin types, including normal, dry and mature skin that crave extra softness. Oily or acne-prone complexions can also use it because its texture is lighter than many traditional waxes, though extremely breakout-prone users may prefer to spot it in leave-on products first to be sure it feels comfortable. Sensitive skin usually responds well since the molecule is considered low irritation.
Formulators can obtain the ingredient from two sources: wool-derived cholesterol or plant sterols that are chemically converted. If you follow a vegan or strict vegetarian lifestyle you will want to confirm with the brand that the plant-based version was used.
No research flags this ester as a concern for women who are pregnant or breastfeeding, as it is not known to penetrate deeply or act hormonally. This is not medical advice and expectant or nursing mothers should run any skincare product past their physician just to be safe.
Dihydrocholesteryl Butyrate does not increase photosensitivity so you do not need to alter your normal sun protection routine when using it. It is also fragrance-free and non-volatile, making it a gentle choice for formulations designed for the delicate eye area.
Potential Side Effects/Adverse Reactions
Reactions to topical Dihydrocholesteryl Butyrate vary from person to person. The points below list potential side effects but keep in mind they are uncommon when the ingredient is properly formulated in a finished product.
- Mild skin irritation such as temporary redness or stinging
- Allergic contact dermatitis in individuals sensitive to cholesterol derivatives or butyric acid esters
- Clogged pores or minor breakouts in users who are extremely acne-prone
- Rare eye irritation if a product migrates into the eye area in high concentration
If you experience any discomfort or adverse reaction stop using the product and consult a healthcare professional or dermatologist for guidance.
Comedogenic Rating
Rating: 1 out of 5. Dihydrocholesteryl Butyrate has a wax like structure that sits lightly on the surface and is chemically closer to skin compatible sterol esters than to heavy plant oils. It spreads easily without forming an occlusive film that can trap debris, which keeps its clogging potential low.
Suitable for acne-prone or breakout-prone skin in most formulas, although extremely oily users may still prefer lighter textures.
Real-world performance depends on the full product recipe, the level of the ester, and how often it is layered with other rich ingredients.
Summary
Dihydrocholesteryl Butyrate works mainly as a skin conditioning agent and emollient. By mimicking the lipids found naturally in the skin it fills in microscopic gaps in the surface, smooths rough patches and slows water loss, so skin feels softer and looks plumper.
While not as famous as shea butter or squalane, this ester sees steady use in mid to high end creams, lip balms and conditioning makeup where a silky cushiony afterfeel is prized.
Safety profiles rate it as low irritation and low sensitizing. As with any new cosmetic however, it is smart to do a quick patch test when trying a product that contains Dihydrocholesteryl Butyrate.
