What Is Sodium Olivamphoacetate?
Sodium Olivamphoacetate is an olive oil–derived ingredient that belongs to a group of mild, amphoteric surfactants. Chemically, it is the sodium salt of an olive oil fatty acid that has been linked to an amino acid–like molecule, giving it a structure that can interact with both water and oils. This dual nature makes it especially good at loosening dirt and oil while staying gentle on skin and hair.
The idea of turning plant oils into cleansers dates back to the mid-20th century when formulators looked for alternatives to harsher sulfates. Olive oil proved attractive because its fatty acid profile is rich in oleic acid, which can be modified to create soft, skin-friendly surfactants. Sodium Olivamphoacetate emerged from this research as one of the milder options and has been used in personal care since the 1990s.
Manufacturing starts with olive oil fatty acids that are reacted with chloroacetic acid and a nitrogen-containing compound called iminodiethanol. The result is an amphoacetate that is then neutralized with sodium hydroxide to make the final, water-soluble salt. The process keeps many of olive oil’s conditioning traits while adding cleansing power.
Thanks to its mildness, you will most often see Sodium Olivamphoacetate in facial cleansers, micellar waters, baby shampoos, body washes, bubble baths, shaving creams and gentle makeup removers. It may also appear in sulfate-free shampoos, pet care washes and sensitive-skin bar soaps.
Sodium Olivamphoacetate’s Cosmetic Benefits/Uses
This ingredient brings several helpful actions to a formula, all of which aim to clean without stripping away too much natural moisture.
- Cleansing: Its amphoteric structure lifts away sweat, oil and makeup while staying kind to the skin barrier, which is why it shows up in products labeled gentle or sulfate-free.
- Hair Conditioning: Derived from olive oil, it leaves behind a thin, smooth film that can reduce static and improve comb-through, a plus for mild everyday shampoos.
- Foam Boosting: It partners well with other surfactants, helping them produce a thicker, creamier lather so the wash feels luxurious even if the base is sulfate-free.
Who Can Use Sodium Olivamphoacetate
Sodium Olivamphoacetate is considered gentle enough for nearly all skin types including sensitive, dry, balanced, oily and acne-prone skin because it cleans without stripping natural moisture. People with a known allergy to olives or olive oil derivatives should proceed cautiously since the ingredient is olive sourced, but such reactions are rare.
The compound is entirely plant derived and no animal-based processing aids are typically used, so it is suitable for vegans and vegetarians.
Current safety data show no specific risks for women who are pregnant or breastfeeding when the ingredient is used topically in rinse-off or leave-on cosmetics. This information is not medical advice, and anyone who is expecting or nursing should confirm product suitability with a healthcare provider just to be safe.
Sodium Olivamphoacetate is not known to cause photosensitivity, meaning it will not make skin more prone to sunburn. It also works well alongside most common skincare actives, making it a versatile choice in multi-step routines.
Potential Side Effects/Adverse Reactions
Individual responses to any cosmetic ingredient can differ. The effects below are possible yet uncommon when products are formulated correctly and used as directed.
- Mild skin irritation such as redness or stinging, most often when used in very high concentrations
- Allergic contact dermatitis in people sensitive to olive derivatives or certain surfactants
- Eye discomfort or tearing if the raw ingredient accidentally gets into the eyes before being diluted
- Temporary dryness or tightness if a formula pairs the surfactant with insufficient moisturizers
If you notice any of these reactions stop using the product and seek advice from a healthcare professional or dermatologist.
Comedogenic Rating
Rating: 1 (very low likelihood of clogging pores)
Sodium Olivamphoacetate is highly water soluble and designed for rinse-off products, so it does not linger on skin long enough to block follicles. Any olive-derived lipids that remain are minimal and lightweight, keeping residue to a bare minimum. For these reasons formulators and dermatology references place its comedogenic potential at the lower end of the scale.
Because of its low rating this ingredient is generally fine for people who are prone to acne or breakouts.
Keep in mind that overall formula matters; if a cleanser is packed with heavy oils or butters the final product could still feel pore-clogging even though the surfactant itself is not.
Summary
Sodium Olivamphoacetate works mainly as a mild cleanser, foam booster and light hair conditioner. Its amphoteric structure lets one end grab oil while the other mixes with water, lifting away dirt without stripping skin or hair and leaving a soft finish. When blended with other gentle surfactants it also thickens and stabilises lather for a richer wash experience.
Although effective it is not as widely used as mainstream surfactants like cocamidopropyl betaine or sodium lauryl sulfate, yet it has carved out a niche in sulfate-free face washes, baby shampoos and sensitive-skin formulas where gentleness is key.
Current safety reviews show a very low risk of irritation or sensitisation when the ingredient is used as intended. It is considered safe for most users including those who are pregnant, breastfeeding, vegan or vegetarian. Still, everyone’s skin is different so it is smart to patch test any new product that features Sodium Olivamphoacetate before adding it to a daily routine.
