INCI: ALUMINUM DILINOLEATE

A safe and effective thickener and stabilizer that improves product texture and shelf life, but offers no direct skin benefit.

In plain English

Aluminum dilinoleate is a synthetic ingredient that helps give creams and lotions a smooth, thick, and stable texture. It prevents the oil and water parts of a formula from separating, so your product stays consistent and doesn't go bad quickly. It doesn't actively moisturize or treat your skin, but it makes the product feel nicer to apply.

Quick decision guide

Useful, but context matters

Aluminum Dilinoleate 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 Aluminum Dilinoleate.
  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

Aluminum dilinoleate is a metal salt made by reacting aluminum with dilinoleic acid (a fatty acid derived from linoleic acid). It is a white to off-white powder used primarily as a thickening and stabilizing agent.

How it works

It works by forming a network of tiny particles that trap oil and water, increasing the viscosity (thickness) of the product. This network also helps keep the formula stable, preventing separation and extending shelf life.

Pros

Improves product feel

Creates a smooth, creamy texture that spreads easily and feels lightweight on the skin.

Boosts formula stability

Helps prevent oil and water from separating, so your product stays effective and doesn't spoil as quickly.

Cons and cautions

No skin benefit

It doesn't moisturize, soothe, or treat the skin—it's purely a texture and stability ingredient.

Synthetic origin

Made in a lab, which may be a turn-off for people who prefer natural or plant-based ingredients.

Best for

  • Anyone using creams, lotions, or makeup who wants a stable, pleasant texture
  • People with normal to oily skin who prefer a non-greasy feel

Use caution if

  • Those strictly avoiding synthetic or aluminum-based ingredients

Usage tips

Look for it in the ingredient list if you want a rich, stable cream that doesn't separate.
It's often used in combination with other thickeners for the best texture.

Safety summary

Aluminum dilinoleate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, and is not known to be toxic. However, it offers no direct skin benefit.

Research notes

Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that aluminum dilinoleate is safe for use in cosmetics. There is limited research on its long-term environmental impact.

Common label clues

Typical concentration
Typically 0.5% to 5%
Regulatory status
Approved for use in cosmetics in the EU, US, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed it and found it safe at typical concentrations.
Common uses
Creams, Lotions, Foundations, Lipsticks, Sunscreens
Environmental note
As a synthetic compound, its environmental impact is not well-studied, but it is not known to be bioaccumulative or toxic to aquatic life at low concentrations.

Good to know

  • Aluminum dilinoleate is not the same as aluminum salts used in antiperspirants—it's a different compound with a different purpose.
  • It is considered safe for use in cosmetics by major regulatory bodies.
