Ingredient review
Sodium Sunflowerseedamphoacetate
INCI: Sodium Sunflowerseedamphoacetate
A gentle, sunflower-derived surfactant that cleanses effectively while being kind to sensitive skin.
In plain English
Sodium Sunflowerseedamphoacetate is a mild cleansing ingredient made from sunflower oil. It works like a gentle soap that lifts dirt and oil from your skin but is much less drying than traditional soaps. Because it's derived from sunflower fatty acids, it's often used in products for sensitive or dry skin, and it's also biodegradable.

Quick decision guide
Easy yes for most routines
Sodium Sunflowerseedamphoacetate 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 Sunflowerseedamphoacetate.
- 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 sunflower fatty acids with amino acids, resulting in a mild amphoteric (both positively and negatively charged) cleansing molecule.
How it works
It reduces the surface tension of water, allowing it to mix with oil and dirt so they can be rinsed away. Its amphoteric nature means it works well in a wide pH range and is less likely to irritate the skin barrier compared to harsher sulfates.
Pros
Ultra-gentle on skin
Its mild amphoteric nature means it cleans without disrupting the skin barrier, making it ideal for daily use on sensitive or compromised skin.
Plant-derived and eco-friendly
Made from renewable sunflower oil and biodegradable, it aligns with sustainable and natural beauty preferences.
Cons and cautions
Milder cleansing power
It may not fully remove heavy, water-resistant makeup or sunscreen, so a double-cleansing step might be needed.
Higher cost
As a specialty surfactant, it is typically more expensive than common sulfates, which can increase product price.
Best for
- People with sensitive, dry, or eczema-prone skin
- Those looking for a sulfate-free, plant-based cleanser
Use caution if
- Individuals who prefer a very high-foam, deep-cleansing experience (may find it too mild)
Usage tips
Safety summary
Sodium Sunflowerseedamphoacetate is considered safe for use in cosmetics. It has a low irritation and sensitization potential, and no significant toxicity concerns have been reported in standard safety assessments.
Research notes
While specific studies on this exact ingredient are limited, the broader class of amphoacetate surfactants (e.g., sodium cocoamphoacetate) is well-documented as mild and safe. Its plant-derived origin and biodegradability are supported by cosmetic ingredient reviews.
Common label clues
- Typical concentration
- 5-15% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics globally; no known restrictions in the EU, US, or Asia.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Derived from sunflower oil, a renewable resource, and readily biodegradable, making it a more sustainable choice compared to petroleum-based surfactants.
Good to know
- It is often combined with other mild surfactants to boost foam and cleaning performance while maintaining gentleness.
- The 'ampho' in its name refers to its amphoteric nature, meaning it can act as either an acid or a base depending on the pH.
