What Is Dipentaerythrityl Tetrahydroxystearate/Tetraisostearate?
Dipentaerythrityl Tetrahydroxystearate/Tetraisostearate is a plant derived ester made by reacting dipentaerythritol, a sugar alcohol, with a mix of hydroxystearic acid and isostearic acid that come from vegetable oils such as castor or soybean. The result is a large, branched molecule that feels silky and stays stable in both high and low temperatures. The ingredient first appeared in color cosmetics in the early 2000s when formulators needed a way to keep pigments evenly dispersed while adding a smooth feel to the skin. Today it is produced in modern esterification facilities where the raw acids and alcohol are heated together in the presence of a catalyst, then purified to remove any by-products. You will most often find it in foundations, lipsticks, cream blushes, moisturizers, sunscreens, primers and some anti aging serums where it helps create a rich yet non greasy texture.
Dipentaerythrityl Tetrahydroxystearate/Tetraisostearate’s Cosmetic Benefits/Uses
This multitasking ester improves both how a product feels and how well it works on the skin
- Skin Conditioning – forms a light, breathable film that locks in moisture, softens rough patches and gives a smooth after-feel so skin looks healthy and supple
- Viscosity Controlling – thickens oil phases and keeps pigments or powders suspended which prevents separation and ensures consistent, easy application
Who Can Use Dipentaerythrityl Tetrahydroxystearate/Tetraisostearate
This silky ester suits normal, dry and combination skin because it helps hold moisture without feeling heavy. Oily or acne-prone skin can usually tolerate it as well since the molecule is large and non-occlusive, though very breakout-prone users may prefer lighter formulas. Sensitive skin typically does fine because the ingredient is non-reactive and fragrance-free.
It is made entirely from plant-derived building blocks and involves no animal by-products, so it is considered suitable for both vegans and vegetarians.
No data suggest any risk specific to pregnancy or breastfeeding when the ingredient is used topically at cosmetic levels. This is not medical advice and anyone who is pregnant or nursing should show the full ingredient list of any product to a healthcare provider before use just to be safe.
The molecule does not increase photosensitivity, meaning it will not make skin more prone to sunburn. It is also odorless and unlikely to interfere with fragrance or active treatments in a routine.
Potential Side Effects/Adverse Reactions
Individual responses to topical Dipentaerythrityl Tetrahydroxystearate/Tetraisostearate can vary. The points below outline potential but uncommon side effects. When the ingredient is used at typical cosmetic levels most people will not notice any of these issues.
- Mild skin irritation such as temporary redness or stinging in very sensitive users
- Contact dermatitis for those with a specific sensitivity to fatty acid esters
- Clogged pores or blemishes in individuals who are extremely acne-prone and using very rich formulas
- Eye irritation if the product migrates into the eye area, especially in liquid makeup
If any discomfort, rash or persistent breakout occurs stop using the product and consult a healthcare professional
Comedogenic Rating
Rating: 1/5
Dipentaerythrityl Tetrahydroxystearate/Tetraisostearate is a big branched molecule that sits on the surface rather than sinking deeply into pores, so it is far less likely to trap oil or dead skin. Industry tests show it does not promote comedone formation at typical use levels, which is why it earns a low score of 1.
Most people who are prone to acne or breakouts can use products containing this ester without added risk, especially when the overall formula is lightweight.
Its comedogenic potential can rise if blended with heavier occlusive oils in very rich creams, so the full formula matters just as much as the single ingredient.
Summary
Dipentaerythrityl Tetrahydroxystearate/Tetraisostearate conditions skin by forming a light breathable film that locks in water and smooths texture, and it controls viscosity by thickening the oil phase so pigments stay evenly distributed. These two roles give makeup a silky glide and help lotions feel rich yet non greasy.
While not as famous as ingredients like dimethicone, it has become a quiet staple in many modern foundations, lipsticks and hybrid skincare products because it is plant derived and performs well in clean beauty formulations.
Safety data are strong with low irritation, no phototoxicity and a very low comedogenic rating, but everyone’s skin is unique so it is smart to patch test any new product that contains this ester before applying it to the whole face.
