What Is Disodium Succinate?
Disodium succinate is the sodium salt of succinic acid, a small organic acid that shows up naturally in sugar cane, certain fruits and even our own cells as part of normal energy production. In cosmetic labs succinic acid is first made by fermenting plant sugars with friendly microbes, then it is neutralized with food-grade sodium hydroxide to form disodium succinate. The resulting crystals are purified, dried and milled into a fine white powder that dissolves easily in water.
The beauty industry first noticed disodium succinate decades ago when food scientists were using it as a flavor booster. Chemists found that the same material helped freshen scent blends and improved how surfactants rinse off the skin, so it gradually made its way into rinse-off and leave-on formulas. Today you can spot it in facial cleansers, body washes, shampoos, sheet masks, toners, lightweight moisturizers and occasional specialty treatments that aim for a clean feel without heavy residues.
Disodium Succinate’s Cosmetic Benefits/Uses
In a formulation disodium succinate pulls double duty, offering the perks below
- Fragrance: It works as a mild flavor and scent enhancer that rounds out perfume notes and helps mask raw material odors, giving products a fresher more balanced smell
- Cleansing: When paired with primary surfactants it buffers pH and improves foam stability which can make cleansers feel smoother and rinse more completely so skin or hair is left comfortable not stripped
Who Can Use Disodium Succinate
Because it is a gentle salt that simply supports fragrance and cleansing, disodium succinate is considered friendly for all major skin types including dry, normal, combination, oily and even sensitive skin. It does not clog pores or leave an occlusive film, so acne-prone users usually tolerate it well. Those with a history of salt sensitivity or very reactive skin may wish to keep an eye on how their skin feels, but outright incompatibility is rare.
The ingredient is made by fermenting plant sugars then neutralizing the resulting acid with mineral-based sodium, so it is suitable for both vegetarians and vegans. No animal-derived materials are involved at any point in the process.
Formulas containing disodium succinate are generally viewed as safe for people who are pregnant or breastfeeding. Still, this is not medical advice and anyone expecting or nursing should show their healthcare provider the full ingredient list of any product they plan to use just to be certain it fits their individual needs.
Disodium succinate is not known to cause photosensitivity. It does not thin the skin or alter its pigment response, so normal sun-safety practices are all that is required.
Potential Side Effects/Adverse Reactions
Responses to topical disodium succinate can vary from person to person. The points below outline potential side effects that have been reported, but they are uncommon when the ingredient is used at the low levels found in cosmetics manufactured within safety guidelines.
- Mild transient stinging or tingling
- Redness or irritation on very sensitive or compromised skin
- Dryness if combined with high concentrations of other salts or aggressive surfactants
- Allergic contact dermatitis in individuals specifically allergic to succinate salts, a reaction that is considered extremely rare
If any of these effects develop, stop using the product and seek advice from a qualified healthcare professional.
Comedogenic Rating
Rating: 0 / 5
Disodium succinate is a small, water-soluble salt that rinses away completely and leaves no oily or waxy residue on the skin. It does not sit in pores or form a film that could trap debris, which is why it earns the lowest possible score on the comedogenic scale. This makes it well suited for people prone to acne or frequent breakouts. Because comedogenicity can shift when ingredients are blended with heavy oils or butters, the overall formula still matters, but disodium succinate itself will not raise the clogging potential.
Summary
Disodium succinate acts mainly as a fragrance enhancer and cleansing aid. It rounds out scent profiles by softening any sharp raw material notes and it supports surfactants by buffering pH and stabilizing foam so cleansers feel gentle and rinse clean. Though it rarely grabs the spotlight on product labels, chemists value it as a quiet multitasker that keeps formulas balanced and user friendly, which is why you will spot it scattered across many everyday cleansers and light leave-ons.
Safety data show very low irritation and virtually no comedogenic risk, so most skin types, including sensitive or acne-prone, tolerate it well. As with any new skincare item it is smart to do a quick patch test before full-face use just to confirm personal compatibility.
