Myristic Acid
Myristic acid is a saturated fatty acid derived from coconut or palm sources, often used in surfactant and emulsifier systems. Cleansing bars and creams use it because it boosts lather, improves texture, and adds a rich, occlusive feel.

Our take
Is Myristic Acid a Good Ingredient?
It's effective for boosting cleanse and lather, but its high comedogenic rating (around 4) means it can congest pores, especially in acne-prone skin, which is why it rates Fair. It's best suited to rinse-off formats, since leave-ons raise breakout risk.
What it does
Skin Benefits
Helps lift away excess sebum and sunscreen residue for a thorough cleanse while leaving skin feeling soft, though those prone to breakouts may find it congesting due to its higher comedogenic potential.
Where you'll find it
Uses in Skincare & Cosmetics
Common in bar soaps, foaming face washes, and shaving soaps; also appears in cream cleansers for richer cleansing textures.
Before you use it
Safety
Generally safe in cosmetics, with low irritation risk for most users. Notable comedogenic risk for blemish-prone skin, particularly in leave-on products; patch test if sensitive. No widely recognized regulatory restrictions for typical use levels.
