Ingredient review
Sodium Tungstate Antimonate
INCI: SODIUM TUNGSTATE ANTIMONATE
Sodium Tungstate Antimonate is a synthetic stabilizer with limited cosmetic research and potential safety concerns; it's best avoided in leave-on products until more data is available.
In plain English
Sodium Tungstate Antimonate is a man-made mineral salt that contains tungsten and antimony. In cosmetics, it's sometimes used to help keep other ingredients stable or to adjust the product's pH (how acidic or alkaline it is). However, it's not a common ingredient in everyday skincare, and there isn't much research on how safe it is for your skin over time. Because it contains antimony, which can be irritating, it's generally not recommended for sensitive skin or for products that stay on your skin for a long time.

Quick decision guide
Read the cautions before using
Sodium Tungstate Antimonate can be useful, but watch for some irritation potential.
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 Tungstate Antimonate.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A synthetic inorganic compound composed of sodium, tungsten, and antimony, used in small amounts as a stabilizer or pH adjuster in some cosmetic formulations.
How it works
It helps maintain the chemical stability of a formula by buffering pH changes or interacting with other ingredients to prevent degradation. Its primary role is functional rather than active on the skin.
Pros
Effective stabilizer
Helps maintain product consistency and shelf life by controlling pH and preventing ingredient breakdown.
Low comedogenic risk
Unlikely to clog pores, making it less problematic for acne-prone skin in rinse-off products.
Cons and cautions
Limited safety research
There is very little published research on the safety of this ingredient for topical cosmetic use, especially for long-term or leave-on application.
Potential irritation
Contains antimony, which can be a skin irritant; may cause redness or stinging in sensitive individuals.
Best for
- Formulators needing a specific pH buffer in non-sensitive products
- Products designed for short contact (e.g., rinse-off cleansers)
Use caution if
- People with sensitive or reactive skin
- Anyone using leave-on products like serums or moisturizers
Usage tips
Safety summary
Safety data for Sodium Tungstate Antimonate in cosmetics is minimal. The presence of antimony raises concerns about potential irritation and long-term toxicity, so it is best used cautiously and only in low concentrations in rinse-off products.
Research notes
There are no peer-reviewed studies specifically on the cosmetic safety of Sodium Tungstate Antimonate. General toxicology data on antimony compounds suggest potential for skin irritation and systemic toxicity with high exposure, but topical cosmetic use involves very low doses.
Common label clues
- Typical concentration
- Very low (typically under 1%)
- Regulatory status
- Not specifically restricted in cosmetics by the FDA or EU, but antimony compounds are generally subject to heavy metal limits due to toxicity concerns.
- Common uses
- Rarely used in mainstream skincare; more common in industrial or specialty products
- Environmental note
- Tungsten and antimony mining can have environmental impacts; synthetic production may involve energy-intensive processes.
Good to know
- Sodium Tungstate Antimonate is more common in industrial applications than in cosmetics.
- Antimony compounds are sometimes used as flame retardants, which raises questions about their suitability for skincare.
