Ingredient review
Sodium Coco-Glucoside Tartrate
INCI: Sodium Coco-Glucoside Tartrate
A gentle, biodegradable surfactant that cleanses effectively while being kind to sensitive skin.
In plain English
Sodium Coco-Glucoside Tartrate is a mild cleansing ingredient made from coconut-derived fatty alcohols and glucose (a sugar). It belongs to a family of surfactants that help water mix with oil and dirt so they can be rinsed away. Unlike harsher soaps, it cleans without stripping the skin’s natural moisture barrier, making it a popular choice for gentle and sensitive-skin formulas.

Quick decision guide
Easy yes for most routines
Sodium Coco-Glucoside Tartrate is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Sodium Coco-Glucoside Tartrate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic surfactant created by reacting coconut fatty alcohols with glucose (from corn or wheat) and then modifying the molecule with tartaric acid (a natural fruit acid). The result is a large, gentle molecule that lifts dirt and oil without penetrating deeply into the skin.
How it works
In a cleanser, this molecule has a water-loving head and an oil-loving tail. When you lather it with water, the tails grab onto sebum and impurities while the heads stay in the water, allowing everything to be rinsed away. Its large molecular size and mild chemistry mean it is less likely to irritate or dehydrate the skin compared to traditional sulfates.
Pros
Ultra-gentle cleansing
Its large molecular structure and mild chemistry make it one of the least irritating surfactants, ideal for compromised or sensitive skin.
Eco-friendly profile
Made from renewable plant sources and readily biodegradable, it has a lower environmental impact than many petroleum-based cleansers.
Cons and cautions
Limited heavy-duty power
It may struggle to dissolve long-wear makeup or waterproof sunscreen, so you might need a double-cleansing step for full removal.
Cost factor
Because it is a specialty mild surfactant, products containing it can be pricier than basic sulfate-based cleansers.
Best for
- People with sensitive, reactive, or eczema-prone skin
- Anyone looking for a gentle daily cleanser that won’t strip moisture
Use caution if
- Those who prefer a high-foam, squeaky-clean feel may find it too mild
Usage tips
Safety summary
Sodium Coco-Glucoside Tartrate is considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk, making it suitable for sensitive skin. No significant safety concerns have been reported in regulatory reviews.
Research notes
While specific studies on this exact molecule are limited, the broader family of alkyl glucoside surfactants (including coco-glucoside) has been well-studied and shown to be mild and non-irritating. Regulatory bodies like the Cosmetic Ingredient Review (CIR) have deemed similar glucoside surfactants safe for cosmetic use.
Common label clues
- Typical concentration
- 1–10% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Facial cleansers, Body washes, Shampoos, Micellar waters
- Environmental note
- Derived from coconut and glucose, it is biodegradable and considered more environmentally friendly than many synthetic surfactants.
Good to know
- Sodium Coco-Glucoside Tartrate is often found in sulfate-free and pH-balanced cleansers.
- It is compatible with other mild surfactants to boost cleansing power without increasing irritation.
