Propylene Glycol Ricinoleate

INCI: Propylene Glycol Ricinoleate

A gentle emollient that helps soften skin and improve product texture, with a low risk of irritation or clogged pores.

In plain English

Propylene Glycol Ricinoleate is a semi-synthetic ingredient made by combining propylene glycol with ricinoleic acid, a fatty acid from castor oil. In skincare, it acts as an emollient, meaning it helps soften and smooth the skin by forming a light, non-greasy film that reduces water loss. It also helps other ingredients spread evenly and gives products a pleasant, silky feel. Because it is mild and unlikely to clog pores, it is often used in moisturizers, cleansers, and makeup removers for sensitive or acne-prone skin.

Quick decision guide

Useful, but context matters

Propylene Glycol 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 Propylene Glycol 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 from propylene glycol and ricinoleic acid (derived from castor oil). It appears as a clear to slightly yellow liquid or soft solid and is used primarily as an emollient and skin-conditioning agent.

How it works

It sits on the skin's surface, forming a thin, breathable barrier that helps lock in moisture without feeling heavy or greasy. This barrier reduces transepidermal water loss (TEWL), which is the water that evaporates from your skin, keeping it hydrated and supple. It also improves the spreadability of other ingredients, making products feel smoother during application.

Pros

Gentle on sensitive skin

With low irritation and comedogenic ratings, it is suitable for most skin types, including those prone to breakouts or redness.

Improves product feel

It gives creams and lotions a silky, non-greasy texture that spreads easily, making your skincare routine more pleasant.

Cons and cautions

Limited hydrating power

As an emollient, it softens skin but does not actively attract water like humectants (e.g., glycerin), so it works best in combination with other hydrating ingredients.

Potential allergen for some

Although rare, castor oil derivatives can trigger allergic reactions in individuals with specific sensitivities, so patch testing is wise.

Best for

  • People with dry or dehydrated skin looking for a lightweight moisturizer
  • Those with sensitive or acne-prone skin who need a non-comedogenic emollient

Use caution if

  • Individuals with a known allergy to castor oil or ricinoleic acid derivatives

Usage tips

Use in moisturizers or serums after water-based products to lock in hydration.
Pair with humectants like hyaluronic acid or glycerin for best moisturizing results.
Apply to slightly damp skin to enhance absorption and barrier function.

Safety summary

Propylene Glycol Ricinoleate is considered safe for cosmetic use with low irritation and comedogenic potential. Rare allergic reactions may occur in individuals sensitive to castor oil derivatives. No significant safety concerns have been raised in regulatory reviews.

Research notes

Research on Propylene Glycol Ricinoleate specifically is limited, but it is structurally similar to other fatty acid esters that are well-studied as safe emollients. The Cosmetic Ingredient Review (CIR) panel has assessed related esters and found them safe for use in cosmetics at typical concentrations.

Common label clues

Typical concentration
Typically 1–5% in leave-on products, up to 10% in rinse-off formulas
Regulatory status
Approved for use in cosmetics in the US (FDA) and EU (CosIng) with no concentration restrictions, though typical use is under 10%.
Common uses
Moisturizers, Cleansers, Lip products, Makeup removers
Environmental note
Propylene glycol and castor oil are generally biodegradable, but the esterification process may involve synthetic steps. Castor oil is a renewable plant resource.

Good to know

  • Propylene Glycol Ricinoleate is often used in 'oil-free' formulations because it provides emollience without a heavy oil feel.
  • It is considered safe for use in cosmetics by major regulatory bodies, including the FDA and the European Commission.
