Glyceryl Diarachidate

INCI: Glyceryl Diarachidate

A gentle, non-greasy emollient that helps creams feel smooth and luxurious without clogging pores.

In plain English

Glyceryl Diarachidate is a synthetic wax made from glycerin and arachidic acid (a fatty acid found in peanut oil and other plant oils). In skincare, it acts as an emollient, meaning it softens and smooths the skin by filling in the tiny gaps between skin cells. It also helps thicken and stabilize creams and lotions, giving them a rich, velvety texture that spreads easily without feeling heavy or greasy. Because it is non-comedogenic (won't clog pores) and very low-irritation, it is a popular choice for sensitive skin formulas.

How reviews are scored

Quick decision guide

Useful, but context matters

Glyceryl Diarachidate 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.

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

Glyceryl Diarachidate is a diester of glycerin and arachidic acid, a long-chain saturated fatty acid. It is produced synthetically for consistent purity and performance, though arachidic acid can be sourced from natural oils like peanut or shea butter. It appears as a waxy solid at room temperature and is incorporated into oil-in-water emulsions to improve viscosity and skin feel.

How it works

In a cosmetic formula, Glyceryl Diarachidate sits at the interface between oil and water droplets, helping to stabilize the emulsion so the product doesn't separate. On the skin, it leaves a thin, non-occlusive film that reduces water loss (transepidermal water loss, or TEWL) without feeling sticky or suffocating. This film also gives a silky, smooth after-feel that makes moisturizers feel more luxurious.

Pros

Gentle on sensitive skin

Glyceryl Diarachidate has a very low irritation potential and is non-comedogenic, making it a safe choice for reactive or acne-prone skin types.

Improves product texture

It gives creams and lotions a smooth, velvety feel that spreads easily and doesn't leave a greasy residue, enhancing the user experience.

Cons and cautions

Synthetic origin

It is manufactured in a lab, which may be a turn-off for consumers seeking naturally derived or 'clean' ingredients.

Limited functional benefits

Its primary role is as a texture enhancer and stabilizer; it doesn't provide active skin benefits like hydration, brightening, or anti-aging.

Best for

Anyone with normal to dry skin looking for a gentle, non-greasy moisturizer
People with sensitive or acne-prone skin who want a low-comedogenic emollient

Use caution if

Those who strictly avoid synthetic ingredients in their skincare routine

Usage tips

Look for this ingredient in moisturizers and creams if you prefer a rich but non-greasy texture.

It works well in combination with humectants like glycerin or hyaluronic acid for balanced hydration.

Safety summary

Glyceryl Diarachidate is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, and is non-comedogenic. The Cosmetic Ingredient Review (CIR) panel has reviewed similar fatty acid esters and found them safe as used.

Research notes

While specific studies on Glyceryl Diarachidate are limited, the broader class of glyceryl fatty acid esters has been extensively evaluated for safety and efficacy as emollients and emulsion stabilizers. The CIR has deemed these ingredients safe in cosmetic formulations.

Common label clues

Typical concentration: 0.5% to 5%
Regulatory status: Approved for use in cosmetics by the FDA and the European Commission. It is listed on the CosIng database as a safe emollient and viscosity controlling agent.
Common uses: Moisturizers, Creams, Lotions, Lip products, Makeup
Environmental note: As a synthetic ingredient, its environmental impact depends on the manufacturing process. It is not known to be bioaccumulative or toxic to aquatic life at typical use concentrations.

Good to know

Glyceryl Diarachidate is often used alongside other fatty acid esters to fine-tune the feel of a product.
Despite its name, it does not contain peanut protein and is considered safe for people with peanut allergies (the arachidic acid is highly purified).
