What Is Tea-Diethanolaminoethyl Polyisobutenylsuccinate?
Tea-Diethanolaminoethyl Polyisobutenylsuccinate is a synthetic compound created by reacting polyisobutenyl-succinic anhydride with triethanolamine. The result is a molecule that carries both water-friendly and oil-friendly parts, letting it mingle smoothly with a wide range of cosmetic ingredients. It traces its roots to surfactant research in the mid-20th century, when chemists looked for gentler alternatives to soap that still removed dirt and oil efficiently. Over time formulators noticed that this ingredient not only cleaned the skin but also helped keep mixed formulas from separating, which made it useful in modern skincare and haircare.
Manufacturing starts with polyisobutene, a petroleum-derived polymer known for its flexible, nonvolatile nature. This polymer is chemically joined to succinic anhydride to form polyisobutenylsuccinic anhydride. When this intermediate reacts with triethanolamine, the final Tea-Diethanolaminoethyl Polyisobutenylsuccinate is produced. Careful control of temperature and pH during the reaction helps achieve a stable, high-purity ingredient ready for cosmetic use.
You will most often see Tea-Diethanolaminoethyl Polyisobutenylsuccinate in facial cleansers, body washes, micellar waters, shampoos, makeup removers, exfoliating masks and sometimes lightweight lotions that need a little help keeping oil and water phases blended.
Tea-Diethanolaminoethyl Polyisobutenylsuccinate’s Cosmetic Benefits/Uses
This ingredient serves more than one purpose in a formula, making it a versatile pick for product developers.
- Cleansing: Its surfactant nature loosens and lifts away sebum, sweat and environmental debris without stripping the skin or hair, giving products a gentle yet effective wash-off performance
- Emulsifying: It stabilizes mixtures that contain both oil and water, preventing separation over time which keeps creams, gels and cleansers smooth, consistent and pleasant to use
Who Can Use Tea-Diethanolaminoethyl Polyisobutenylsuccinate
This ingredient is generally well tolerated by most skin types including normal, oily, combination and even sensitive skin, thanks to its mild surfactant profile that cleans without excessive stripping. Very dry or eczema-prone complexions might notice a slight tightness if the overall formula lacks added moisturizers, so those users may prefer products that pair it with richer emollients.
The compound is fully synthetic and contains no animal-derived matter so it is suitable for both vegetarians and vegans. Manufacturing does not rely on animal testing in regions that prohibit such practices though finished products may be subject to differing local regulations.
No data indicate that Tea-Diethanolaminoethyl Polyisobutenylsuccinate is unsafe for pregnant or breastfeeding women when used topically at customary cosmetic concentrations. This is not medical advice and anyone who is pregnant or nursing should consult a healthcare professional before adding new skincare items, especially if using multiple active ingredients.
The molecule does not absorb UV light and is not known to make skin more sensitive to sunlight so it is not considered photosensitizing. It is also fragrance-free and void of known hormonal activity making it a low-risk option for people avoiding potential endocrine disruptors.
Potential Side Effects/Adverse Reactions
Responses to topical Tea-Diethanolaminoethyl Polyisobutenylsuccinate differ from person to person. The points below outline possible although uncommon side effects. When the ingredient is included at standard levels by reputable manufacturers most users experience none of these issues.
- Mild skin irritation such as temporary redness stinging or tightness
- Allergic contact dermatitis in individuals sensitized to triethanolamine derivatives
- Eye irritation if the product accidentally enters the eyes during use
- Excessive dryness or slight flaking in people with very dry or compromised skin barriers
- Rare interaction with other potent exfoliants leading to cumulative irritation
If any of these effects occur discontinue use and seek advice from a healthcare professional or dermatologist.
Comedogenic Rating
Rating: 1 / 5
Tea-Diethanolaminoethyl Polyisobutenylsuccinate is primarily a water-compatible surfactant so it rinses off easily and does not linger in pores. While it carries a stretchy hydrocarbon tail from polyisobutene that could, in theory, sit on the skin, its strong affinity for water and its cleansing action keep buildup to a minimum which is why formulators regard it as very low risk for clogging. It is therefore considered suitable for people prone to acne or breakouts.
As with all surfactants the finished product formula matters; pairing it with heavy occlusive oils could raise the overall comedogenicity even if the ingredient itself is low.
Summary
Tea-Diethanolaminoethyl Polyisobutenylsuccinate works as a dual-purpose helper in cosmetics. Its amphiphilic structure grabs onto oil with its polyisobutene side and water with its triethanolamine-modified end which lets it lift away grime while also holding oil and water together. This makes it a gentle cleanser and a steady emulsifier in solutions ranging from face wash to micellar water.
Despite its practical benefits it is still a bit of a niche choice compared with mainstream surfactants like sodium laureth sulfate or polysorbates so you will mostly spot it in specialist or mid-tier formulas that aim for mildness.
Current safety data show a low irritation profile when used at normal cosmetic levels and no evidence of long-term harm. Still each person’s skin is unique so it is smart to patch test any new product that includes this ingredient especially if you have a history of sensitivity.
