Ingredient review
Ophiopogon Extract Stearate
INCI: Ophiopogon Japonicus Extract Stearate
A gentle, semi-synthetic emollient derived from a traditional Asian herb, offering mild skin conditioning with limited but promising research.
In plain English
Ophiopogon Extract Stearate is a lab-made ingredient that combines an extract from the mondo grass plant (Ophiopogon japonicus) with stearic acid, a fatty acid found in cocoa butter and shea butter. The result is a smooth, skin-softening agent that helps moisturize and condition the skin. It's often used in creams and serums to improve texture and provide a silky feel without being greasy. While the plant extract has a history in traditional medicine for soothing and hydrating, the stearate version is designed to be more stable and effective in skincare formulas.

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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A semi-synthetic compound created by reacting an extract of Ophiopogon japonicus (also known as mondo grass or dwarf lilyturf) with stearic acid. This process forms an ester that is more lipophilic (oil-loving) than the original extract, making it easier to incorporate into oil-based and emulsion products.
How it works
It works primarily as an emollient, meaning it fills in the gaps between skin cells to smooth and soften the skin's surface. The stearate portion helps the ingredient spread evenly and form a light, protective film that reduces water loss. The plant extract component may provide additional antioxidant and soothing benefits, though these are less pronounced in the ester form.
Pros
Gentle on skin
With low irritation and comedogenic risk, it's a safe choice for sensitive or acne-prone skin types.
Improves product feel
Adds a smooth, silky texture to creams and serums without leaving a heavy or greasy residue.
Cons and cautions
Limited research
Most studies focus on the raw plant extract, not the stearate ester, so its specific benefits are not well-documented.
Mild effects
It primarily acts as an emollient; don't expect dramatic anti-aging or hydration results from this ingredient alone.
Best for
- People with dry or dehydrated skin looking for a gentle emollient
- Those with sensitive skin who want a low-irritation moisturizing ingredient
Use caution if
- Individuals with known allergies to stearic acid or Ophiopogon japonicus (rare)
- Those seeking strong antioxidant or anti-aging effects from a single ingredient
Usage tips
Safety summary
Ophiopogon Extract Stearate is considered safe for topical use with a low risk of irritation or clogged pores. Allergic reactions are rare. As with any new ingredient, patch testing is recommended for those with very sensitive skin.
Research notes
Research on Ophiopogon japonicus extract shows antioxidant and anti-inflammatory potential, but studies on the stearate ester are minimal. Current evidence is emerging and mostly based on the plant's traditional use and preliminary lab data.
