What Is Disodium Tetrapropenyl Succinate?
Disodium Tetrapropenyl Succinate is a salt made from tetrapropenyl succinic acid and sodium. Chemically it belongs to the succinate family, which comes from succinic acid, a small organic acid that can be sourced from petroleum feedstocks or fermented sugars. The “tetrapropenyl” part means four propene side chains are attached, giving the molecule a partly oily nature that helps it mix with both water and oils.
The ingredient first showed up in industrial cleaners where it kept metal parts from rusting. Its dual talent for fighting corrosion and lifting away dirt soon caught the eye of cosmetic chemists looking for milder ways to cleanse skin and hair without harsh solvents. To make it, manufacturers react tetrapropenyl succinic anhydride with sodium hydroxide in water. The result is a water-soluble powder or liquid concentrate that is easy to add during the cool-down phase of a formula.
Today you will mainly see Disodium Tetrapropenyl Succinate in face and body washes, shampoos, bubble baths, micellar waters, and some clay or cream masks where gentle cleansing and formula stability are both needed. It can also appear in certain anti-pollution or men’s grooming products that sit in metal containers because it helps protect the package from rust.
Disodium Tetrapropenyl Succinate’s Cosmetic Benefits/Uses
This ingredient serves a couple of practical roles that improve how a product works and how long it lasts on the shelf.
- Anticorrosive – Helps stop metal parts of packaging, caps, or aerosol cans from rusting which keeps the product looking good and prevents unwanted metallic particles from getting into the formula
- Cleansing – Acts as a mild surfactant that loosens dirt, oil, and daily grime so they can be rinsed away leaving skin and hair feeling fresh without a stripped or tight sensation
Who Can Use Disodium Tetrapropenyl Succinate
Products featuring Disodium Tetrapropenyl Succinate are generally well tolerated by all skin types including oily, combination, dry and sensitive because the molecule is mild and water soluble so it rinses away without leaving a heavy residue. Very reactive or eczema-prone skin might still prefer a simpler formula but the ingredient itself is not known to be harsh or pore clogging.
The compound is synthetically produced from petrochemical or plant-fermented feedstocks and no animal-derived substances are involved during standard manufacturing, making it suitable for vegans and vegetarians.
There are no published concerns about its use during pregnancy or while breastfeeding. Still, this is not medical advice and anyone who is pregnant or nursing should ask a health professional before adding new personal care products, just to be extra safe.
Disodium Tetrapropenyl Succinate does not increase photosensitivity so it will not make skin more prone to sunburn. It is also compatible with most common skincare actives such as niacinamide, glycerin and mild exfoliating acids.
Potential Side Effects/Adverse Reactions
Responses to topical Disodium Tetrapropenyl Succinate vary from person to person. The points below outline possible reactions but they are uncommon when the ingredient is used at the low levels typical of finished cosmetics.
- Transient skin irritation such as redness stinging or dryness in very sensitive individuals
- Allergic contact dermatitis marked by itching swelling or small rash-like bumps in those with a specific allergy to succinate salts
- Eye irritation or watering if a cleanser accidentally enters the eyes before rinsing
If any unwanted reaction occurs stop using the product and consult a qualified healthcare provider or dermatologist.
Comedogenic Rating
Rating: 0 / 5
Disodium Tetrapropenyl Succinate is highly water soluble and rinses off cleanly so it does not sit in pores or form an occlusive film that could trap sebum. It also lacks heavy oily chains or waxy fractions that typically raise the risk of clogged pores. Because of this profile it is considered non-comedogenic.
Suitable for acne-prone and breakout-prone skin.
No studies hint at the ingredient influencing sebum production or bacterial growth so there is no indirect pathway that would boost comedogenicity.
Summary
Disodium Tetrapropenyl Succinate mainly offers two perks: it keeps formulas stable by preventing rust in metal packaging and it provides gentle cleansing power that lifts dirt and oil without stripping the skin barrier. It does this thanks to its salt structure that chelates metal ions while its partly oily side chains give it mild surfactant action.
While not a star buzzword on labels, it shows up quietly in cleansers, shampoos and bath products where formulators need a dependable dual-purpose helper. Usage levels are low, safety data are solid and reports of irritation are rare, making it a low-risk addition to most routines. As with any new product though, a quick patch test is a smart move to rule out individual sensitivities.
