What Is Peg-7/Ppg-2 Pentaerythrityl Triacrylate/Dipropylaminopropionate?
Peg-7/Ppg-2 Pentaerythrityl Triacrylate/Dipropylaminopropionate is a lab made polymer created by linking small units of polyethylene glycol, polypropylene glycol and pentaerythritol triacrylate, then reacting the chain with a mild amine called propylaminopropionate. The result is a clear lightweight liquid that spreads easily on skin and hair and dries to form an invisible flexible film. Chemists first explored this family of polymers in the late 1990s while looking for ingredients that could boost the staying power of makeup without leaving a stiff feel. The ingredient is produced in closed reactors where the acrylic parts undergo controlled free radical polymerization, followed by a finishing step that grafts on the amine portion to improve softness and water resistance. Because every step happens under strict temperature and pH control, the finished material is consistent and free from harsh residual monomers.
Its film forming talent makes it popular in products that need to stay put such as long wear foundations, primers, liquid lipsticks, mascaras, brow gels and eyeliners. It also turns up in hair styling creams, glossing sprays, sunscreens, sheet masks and some anti aging serums where a smooth sealing layer helps lock in moisture and active ingredients.
Peg-7/Ppg-2 Pentaerythrityl Triacrylate/Dipropylaminopropionate’s Cosmetic Benefits/Uses
In formulas this ingredient mainly serves one purpose but it is a valuable one.
Film forming: Once the product is applied the polymer dries into a thin flexible film that clings to skin or hair. This film boosts water and smudge resistance, helps pigments stay vivid, reduces transfer to clothing and can even lend a soft blurring effect to fine lines. Because the film is breathable it avoids the tight or flaky feel some older fixatives caused, so wearers get longer lasting results with day long comfort.
Who Can Use Peg-7/Ppg-2 Pentaerythrityl Triacrylate/Dipropylaminopropionate
This polymer is considered gentle enough for most skin types including oily, dry, combination and normal skin. Its breathable film does not trap large amounts of oil or sweat so even acne prone users usually tolerate it well. Extremely sensitive or highly reactive skin may notice a slight tightness if the formula contains a high level of the film former, but that is uncommon.
The ingredient is synthetic and contains no animal derived substances, so it is suitable for vegans and vegetarians. It is also not routinely tested on animals by most raw material suppliers, though finished product policies depend on the brand.
No specific warnings exist for pregnant or breastfeeding women using topical products that include this polymer. It is not known to penetrate deeply or enter the bloodstream. This is not medical advice and anyone who is pregnant or nursing should consult a healthcare professional before starting any new cosmetic just to be safe.
Peg-7/Ppg-2 Pentaerythrityl Triacrylate/Dipropylaminopropionate does not cause photosensitivity and will not make skin more prone to sunburn. It can even help sunscreens stay in place by forming a water resistant layer.
Potential Side Effects/Adverse Reactions
Side effects from topical use vary from person to person. The points below list potential reactions, but most people will not experience them when the ingredient is used at standard cosmetic levels.
- Mild skin irritation such as redness or itching in very sensitive individuals
- Temporary tight feel on very dry skin if the formula lacks sufficient emollients
- Eye irritation if the raw ingredient or a high concentration product accidentally gets into the eyes
- Contact dermatitis in the rare case of an individual allergy to acrylate type polymers
If any discomfort, persistent redness or swelling occurs stop using the product and seek medical advice.
Comedogenic Rating
Rating: 1 (very low)
This polymer forms a breathable film that sits on the surface and is too large to seep into pores where clogging starts. It is frequently used in long wear makeup aimed at oily or acne prone skin without reports of an increase in breakouts. Because the base structure is lightweight and non-greasy it has little affinity for sebum, so it does not trap oil inside the follicle.
Suitable for people prone to acne or congestion in most cases.
As with any film former, buildup could occur if heavy products are layered repeatedly without proper cleansing so thorough makeup removal is still important.
Summary
Peg-7/Ppg-2 Pentaerythrityl Triacrylate/Dipropylaminopropionate is mainly a film forming agent that makes makeup, sunscreens and hair products last longer, resist water and stay vibrant. It achieves this by drying into a flexible micro-mesh that clings to skin or hair yet allows airflow so the surface does not feel suffocated.
While not as famous as silicones or traditional acrylates it has carved out a niche in long wear cosmetics that need a light, comfortable hold. Brands appreciate its balance of staying power and pleasant texture so its use is slowly growing.
Current safety data show it is low risk for irritation or acne and it does not penetrate deeply. Still, everyone’s skin is different so it is smart to patch test any new product containing this ingredient to confirm personal compatibility.
