In plain English

Acetyl Glyceryl Ricinoleate is a modified version of a fatty acid found in castor oil. It is used in skincare and makeup to help the skin feel smooth and soft. Unlike some heavy oils, it spreads easily and leaves a light, non-sticky feel, making it a popular choice for moisturizers and lip balms.

Quick decision guide

Useful, but context matters

Acetyl Glyceryl Ricinoleate is generally a lower-concern ingredient when the full formula suits your skin.

Plain-English read

Treat this as a practical screening step before you compare products that contain this ingredient.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Acetyl Glyceryl Ricinoleate.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A semi-synthetic ester created by reacting castor oil fatty acids with glycerin and acetic acid. It functions as an emollient and skin conditioning agent.

How it works

It forms a thin, breathable film on the skin's surface that helps reduce water loss and improve skin softness. Its molecular structure allows it to spread evenly and absorb quickly without leaving a heavy residue.

Pros

Lightweight feel

Unlike heavy oils, it absorbs quickly and leaves skin feeling soft without a greasy residue, making it ideal for daytime use.

Gentle on skin

It has a low irritation and comedogenic risk, so it is unlikely to clog pores or cause breakouts for most skin types.

Cons and cautions

Plant-derived source

It is derived from castor oil, which may not be suitable for those avoiding plant-based ingredients due to allergies or ethical preferences.

Limited research

Compared to more common emollients like glycerin or squalane, there is less published research on its long-term skin benefits and safety.

Best for

  • People with normal to dry skin looking for lightweight hydration
  • Those who prefer non-greasy moisturizers and lip products

Use caution if

  • Individuals with a known allergy to castor oil or its derivatives

Usage tips

Look for it in moisturizers and lip balms for a silky, non-sticky finish.
It works well in combination with humectants like glycerin for added hydration.

Safety summary

Acetyl Glyceryl Ricinoleate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. As with any ingredient, patch testing is recommended for those with sensitive skin or known allergies.

Research notes

While not as extensively studied as some common emollients, available safety assessments and cosmetic ingredient reviews support its use as a skin conditioning agent. Its properties are well understood through its chemical structure and similarity to other castor oil derivatives.

Common label clues

Typical concentration
1% to 10%
Regulatory status
Approved for use in cosmetics in the US, EU, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
Common uses
Moisturizers, Lip products, Makeup removers, Body lotions
Environmental note
Castor oil is a renewable plant resource, but its cultivation can involve water and land use considerations. The acetylation process is a standard chemical modification.

Good to know

  • It is often used in makeup removers because it helps dissolve makeup without stripping the skin.
  • The 'acetyl' modification makes it less greasy than plain castor oil.
