INCI: Myristic/Palmitic/Stearic/Ricinoleic/Eicosanedioic Glycerides

A gentle emollient blend that helps soften and smooth skin without heavy greasiness.

beautyskincareemollient

In plain English

This ingredient is a mixture of fats (glycerides) made from several fatty acids, including myristic, palmitic, stearic, ricinoleic, and eicosanedioic acids. In skincare, it works as an emollient, meaning it fills in the tiny gaps between skin cells to make your skin feel softer and smoother. It also helps other ingredients spread more evenly and can improve the texture of creams and lotions. Because it's a blend, it's generally well-tolerated and unlikely to clog pores.

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 complex mixture of glycerides (fat molecules) created by combining glycerol with a specific set of fatty acids. These fatty acids are commonly found in natural oils like palm oil, castor oil, and shea butter, but here they are synthesized or purified for consistent performance.

How it works

When applied to the skin, the glycerides form a thin, non-occlusive film that reduces water loss and improves skin softness. The different fatty acid chain lengths allow it to absorb at different rates, providing both immediate and longer-lasting moisturization without a heavy feel.

Pros

Gentle on skin

The blend of fatty acid glycerides is designed to be non-irritating and suitable for sensitive skin types, making it a safe choice for daily moisturizers.

Improves product feel

It helps creams and lotions spread smoothly and absorb quickly, so you get the moisturizing benefits without a sticky or greasy residue.

Cons and cautions

Sourcing concerns

Some of the fatty acids may be derived from palm oil, which has environmental and sustainability issues. Look for brands that use certified sustainable sources.

Limited research

While the individual fatty acids are well-studied, there is less published research specifically on this exact blend, so its unique benefits are based on formulation experience rather than clinical trials.

Best for

  • People with dry or normal skin looking for a lightweight moisturizer
  • Those with sensitive skin who tolerate simple emollients well

Use caution if

  • Individuals with a known allergy to any of the component fatty acids (rare)

Usage tips

Apply to slightly damp skin to enhance absorption and maximize softness.
Use in combination with humectants like glycerin for balanced hydration.

Safety summary

Generally recognized as safe for topical use. Low irritation and comedogenic risk. No significant safety concerns reported in cosmetic concentrations.

Research notes

Individual fatty acid glycerides are well-documented for emollient properties. The specific blend lacks extensive clinical trials but is widely used in commercial products with good tolerability.
