What Is Disodium Amodimethicone Disuccinamide?
Disodium Amodimethicone Disuccinamide is a silicone based ingredient created when amodimethicone, a well known conditioning silicone, reacts with succinic acid and is then neutralized with sodium ions. The result is a salt that is water dispersible yet still keeps the smooth feel that silicones are loved for. It entered the cosmetic scene in the late 1990s as brands looked for easier to rinse silicones that would not build up on hair and skin.
The manufacturing process starts with amodimethicone, which is reacted with plant derived succinic acid under controlled heat. Adding a small amount of sodium hydroxide turns the product into its disodium salt form, improving compatibility with water based formulas. After filtration and quality checks the ingredient is supplied as a clear fluid or milky dispersion ready for use.
You will most often spot Disodium Amodimethicone Disuccinamide in hair masks, leave in conditioners, anti frizz serums, curl creams, lightweight moisturizers and treatment lotions that aim to give a silky slip without a heavy feel.
Disodium Amodimethicone Disuccinamide’s Cosmetic Benefits/Uses
This ingredient serves one main purpose in cosmetics and that single role brings noticeable benefits to a formula.
Viscosity controlling: It helps adjust the thickness of a product so it spreads easily yet stays where you put it. By fine tuning flow it lets a conditioner coat hair evenly or allows a serum to glide over skin without dripping. The controlled texture also improves the overall sensory feel giving a smooth lightweight finish that users associate with premium care products.
Who Can Use Disodium Amodimethicone Disuccinamide
This silicone derivative is considered gentle enough for all skin and hair types including dry, normal, oily and sensitive. Because it is water dispersible and lighter than many classic silicones it seldom weighs hair down or forms a heavy film on skin, making it a good pick for fine hair, combination skin and anyone who dislikes a greasy after feel.
The ingredient is manufactured from synthetic silicone and plant sourced succinic acid with no animal by products, so it is suitable for vegans and vegetarians.

- Rare skin irritation such as temporary redness, itching or a mild burning sensation in individuals with very reactive skin
- Allergic contact dermatitis in users who are specifically sensitized to silicones or succinic acid derivatives
- Eye irritation if the product accidentally gets into the eyes, leading to stinging or watering until rinsed out
- Product buildup on hair strands with extremely heavy or frequent use which can leave hair looking limp or dull
- Potential pore clogging in a small subset of acne prone users when the ingredient is used in rich leave on facial products

Comedogenic Rating
Rating: 1/5
Disodium Amodimethicone Disuccinamide creates a light breathable film that rinses away easily, so it seldom blocks pores. Because it is water dispersible it is less likely to build up than heavier silicones, keeping the clogging risk low. It still counts as a film-former which is why the score is not zero.
Most blemish prone users can use products containing this ingredient without issues, though very congested skin may prefer to limit leave-on exposure.
No data links it to increased sebum or growth of acne-causing bacteria and normal cleansing routines remove any residue.
Summary
Disodium Amodimethicone Disuccinamide’s key job is viscosity control, giving creams, serums and conditioners the ideal thickness to spread smoothly while leaving a silky lightweight finish. It does this by dispersing evenly in water based formulas then laying down a micro-thin conditioning layer when applied.
Although it is not a household name it has a loyal following among formulators who want the softness of silicones without heavy buildup, so you will spot it in many contemporary hair treatments and a growing number of skin care launches.
Safety reviews rate it as low risk for irritation, sensitization or systemic toxicity, making it suitable for most users. Still, personal sensitivity can never be ruled out so a quick patch test is always a smart move before fully committing to any new product that contains it.
