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 C12-14 Hydroxyalkyl Hydroxyethyl Beta-Alanine.
- 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 synthetic surfactant derived from beta-alanine (an amino acid) and C12-14 fatty alcohols. It belongs to the family of amino-acid-based cleansers, known for their gentle, low-irritation profile.
How it works
It works by reducing the surface tension between water and oil, allowing impurities to be lifted away and rinsed off. Its molecular structure is large and mild, so it cleans without penetrating deeply into the skin or stripping natural oils.
Pros
Very gentle on skin
Its large molecular structure means it doesn't penetrate the skin barrier, making it ideal for sensitive or compromised skin.
Maintains moisture balance
Unlike many traditional surfactants, it cleans without stripping natural oils, helping your skin stay hydrated and comfortable.
Cons and cautions
Low foam production
It produces a creamy, low-lather experience, which may not satisfy those who associate foam with effective cleansing.
Limited standalone power
On its own, it may struggle to remove heavy, waterproof makeup or sunscreen, so it's often blended with other cleansers.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Anyone wanting to avoid harsh sulfates like SLS or SLES
Use caution if
- Those who prefer a high-foam, bubbly cleansing experience
