What Is Bis-Diglyceryl Polyacyladipate-1?
Bis-Diglyceryl Polyacyladipate-1 is a plant-derived ester blend created by reacting glycerin with adipic acid and a mix of medium to long chain fatty acids such as octanoic, decanoic, isooctadecanoic and 12-hydroxyoctadecanoic acids. The result is a soft, buttery substance that feels similar to petrolatum yet remains free of mineral oil. First introduced in the late 1990s as part of a movement toward greener alternatives to petroleum jelly, it quickly found a place in skin care because it offers the same cushiony texture without the greasy after-feel. Production starts with sustainable vegetable oils that are split into fatty acids then esterified with diglycerin before being polymerized with adipic acid, yielding a stable semi-solid that resists oxidation and temperature swings.
You will see Bis-Diglyceryl Polyacyladipate-1 in lip balms, stick foundations, tinted moisturizers, rich face creams, body butters, overnight masks and any formula that needs a substantial yet breathable occlusive layer.
Bis-Diglyceryl Polyacyladipate-1’s Cosmetic Benefits/Uses
Formulators rely on this ingredient because it covers two key roles that directly translate to smoother, softer skin.
- Skin Conditioning: Forms a protective film that traps water inside the skin so it stays hydrated longer which helps reduce the look of flakiness and rough patches
- Emollient: Fills in microscopic gaps between skin cells making the surface feel silky and cushioning active ingredients so the product glides on evenly
Who Can Use Bis-Diglyceryl Polyacyladipate-1
This cushy plant-based ester suits most skin types, especially dry or mature skin that needs extra cushioning and moisture retention. Normal and combination skin usually tolerate it well in balanced formulas. Extremely oily or acne-prone complexions may find it feels too rich if used at high levels because the thick occlusive layer can trap excess sebum and debris.
Because it is synthesized entirely from vegetable oils and contains no animal derivatives or by-products, Bis-Diglyceryl Polyacyladipate-1 is appropriate for vegans and vegetarians.
The ingredient has no known hormonal activity and is considered non-irritating, so topical use during pregnancy or while breastfeeding is generally regarded as low risk. This is not medical advice and anyone who is pregnant or nursing should still clear any new skincare product with a healthcare professional to be safe.
Unlike certain botanicals or exfoliating acids, Bis-Diglyceryl Polyacyladipate-1 does not increase photosensitivity, so it will not make skin more prone to sunburn. It is also fragrance-free and free of common sensitizers, making it a good option for people who react to perfumes or essential oils.
Potential Side Effects/Adverse Reactions
Reactions to topical Bis-Diglyceryl Polyacyladipate-1 differ from person to person. The following is a list of potential side effects only. When the ingredient is formulated and used correctly most people experience none of these issues.
- Clogged pores or milia in very oily or acne-prone skin
- Rare cases of contact dermatitis or redness in individuals allergic to fatty acid esters
- Greasy feel or unwanted shine when applied too heavily
If irritation, breakouts or any other unwanted reaction occurs discontinue use and consult a healthcare professional or dermatologist.
Comedogenic Rating
Rating: 2/5 – Bis-Diglyceryl Polyacyladipate-1 has a fairly low tendency to block pores because its molecular structure is bulkier and less sticky than simple plant oils, yet it still forms an occlusive film that can trap sebum if used in heavy concentrations. Most users with balanced or dry skin will not break out, but those who are highly prone to acne may notice clogged pores if the formula also contains other rich lipids or if it is applied thickly.
In short, the ingredient is usually fine for breakout-prone skin when used in lightweight products, but people with persistent acne should keep an eye on how their skin responds.
Formulas that pair this ester with oil-absorbing ingredients like silica or starches often feel lighter and are less likely to cause congestion.
Summary
Bis-Diglyceryl Polyacyladipate-1 works as a skin-conditioning emollient that softens rough patches, locks in moisture and delivers a plush glide. It achieves these benefits by forming a breathable barrier over the skin while its fatty acid chains fill in tiny surface gaps for a smoother feel.
Although not as famous as botanical butters or petrolatum, this plant-based ester enjoys steady popularity among formulators looking for a vegan mineral-oil alternative that still gives a cushiony texture.
Overall safety is considered high with very low rates of irritation or allergenicity. As with any new skincare product a quick patch test on a small area is wise to confirm personal compatibility.
