What Is Sodium Cocoyl Hydroxyethyl Beta-Alaninate?
Sodium Cocoyl Hydroxyethyl Beta-Alaninate is a mild surfactant made by joining coconut-derived fatty acids with a modified form of the amino acid beta alanine, then neutralizing the product with sodium hydroxide. The result is a water-soluble powder or liquid that carries a gentle cleansing charge.
The push for milder cleansers in the early 1990s led formulators to explore amino acid surfactants, and this ingredient quickly gained popularity thanks to its skin-friendly profile. Today it is produced in large batches using eco-minded manufacturing that starts with renewable coconut oil, making it a common choice for brands that spotlight sustainable sourcing.
You will most often see Sodium Cocoyl Hydroxyethyl Beta-Alaninate in facial cleansers, body washes, shampoos, baby care washes, micellar waters and shaving foams. Its ability to clean without stripping also makes it useful in sulfate-free bars and low-irritation toothpaste. Although primarily a cleanser it can be blended into masks or exfoliating gels to help them rinse away smoothly.
Sodium Cocoyl Hydroxyethyl Beta-Alaninate’s Cosmetic Benefits/Uses
This ingredient brings a short yet valuable list of functions to personal care formulas
- Cleansing: Acts as a surfactant that lifts away oil, sweat and product buildup while maintaining the skin’s natural moisture balance so the finished cleanser feels gentle rather than squeaky
- Foaming: Creates a creamy, stable lather that improves spreadability and gives users the satisfying sensation of a rich wash even in sulfate-free products
Who Can Use Sodium Cocoyl Hydroxyethyl Beta-Alaninate
This gentle surfactant suits most skin types, including sensitive, oily, combination and mature skin, because it cleans without stripping natural lipids. Extremely dry or eczema-prone skin can also tolerate it well since the molecule is mild and has a skin-friendly pH profile.
It is plant derived from coconut oil, so it is appropriate for vegans and vegetarians. No animal by-products are used in its standard manufacturing process.
Current research shows no specific risks for pregnant or breastfeeding women when the ingredient is used in rinse-off products. Still, this is not medical advice and anyone who is expecting or nursing should have a doctor review any skincare they are considering.
The ingredient does not make skin more sensitive to the sun, so there is no additional photosensitivity concern. It is also safe for color-treated hair and daily use.
Potential Side Effects/Adverse Reactions
Responses to topical Sodium Cocoyl Hydroxyethyl Beta-Alaninate vary from person to person. The following are potential side effects that can occur, although they are uncommon when the ingredient is properly formulated and used as directed.
- Mild transient eye irritation if the cleanser gets into the eyes
- Temporary skin tightness or dryness when used in a high-foaming formula on very dry skin
- Rare allergic contact dermatitis presenting as redness, itching or small bumps
- Slight stinging on broken or freshly shaved skin
If any of these effects occur discontinue use and consult a healthcare professional.
Comedogenic Rating
Rating: 0 / 5
Sodium Cocoyl Hydroxyethyl Beta-Alaninate is a water-soluble surfactant that does not linger on the skin because it is designed to be rinsed away. It has no oily or waxy residue that could block pores, and there is no data linking it to comedone formation even in higher use levels. For that reason it earns a solid zero on the comedogenic scale.
Suitable for acne-prone or breakout-prone skin.
Because it is usually part of a blend, the overall pore-friendliness of a finished cleanser will also depend on the other surfactants, oils and thickeners in the formula.
Summary
Sodium Cocoyl Hydroxyethyl Beta-Alaninate cleanses and foams. The coconut-derived fatty acid tail grabs onto excess sebum and dirt while the beta alanine head remains comfortable for skin, letting the ingredient surround grime and lift it away when you rinse. Its stable bubbles produce a creamy lather that feels luxurious even in sulfate-free products.
It has become a go-to choice for brands that want a mild, plant-based surfactant so you will spot it in everything from prestige face washes to budget shampoos. Although not as famous as traditional sulfates, its presence is steadily growing as consumers look for gentler alternatives.
Overall safety is high, with very low irritation and no established systemic concerns. As with any new skincare product it is wise to perform a quick patch test first to make sure your individual skin stays happy.
