INCI: Hydrogenated Dilinoleyl Alcohol

A gentle, plant-based emollient that softens skin and improves product texture without clogging pores.

In plain English

Hydrogenated Dilinoleyl Alcohol is a fatty alcohol made from linoleic acid (a fatty acid found in plant oils). It's processed to be stable and non-greasy, so it works as a skin softener and helps other ingredients spread smoothly. Unlike some alcohols, it won't dry or irritate your skin.

Quick decision guide

Useful, but context matters

Hydrogenated Dilinoleyl Alcohol 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 Hydrogenated Dilinoleyl Alcohol.
  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 hydrogenated fatty alcohol derived from linoleic acid, typically sourced from plant oils like sunflower or safflower. It is a waxy solid at room temperature and is used to improve the feel and stability of cosmetic products.

How it works

It sits on the skin's surface to reduce water loss (like a gentle barrier) and gives products a silky, non-sticky feel. It also helps stabilize emulsions (mixtures of oil and water) so the product stays smooth and doesn't separate.

Pros

Gentle on skin

Hydrogenated Dilinoleyl Alcohol has a very low irritation risk, making it suitable for sensitive or reactive skin types.

Non-comedogenic

It has a low comedogenic rating, meaning it's unlikely to clog pores or cause breakouts for most people.

Cons and cautions

May feel heavy for oily skin

In high concentrations, it can leave a slightly waxy feel that some with very oily skin may not prefer.

Limited research

While safe and effective as an emollient, there are few studies on its long-term skin benefits beyond basic moisturization.

Best for

  • People with dry or normal skin looking for a gentle, non-irritating moisturizer
  • Anyone who prefers plant-derived, low-comedogenic ingredients

Use caution if

  • Those with extremely oily or acne-prone skin may prefer lighter emollients like squalane

Usage tips

Look for it in moisturizers and lip balms for a smooth, non-sticky finish.
If you have oily skin, try products where it's listed lower on the ingredient list to avoid a heavy feel.

Safety summary

Hydrogenated Dilinoleyl Alcohol is considered safe for cosmetic use with a low irritation and comedogenic risk. It is not associated with significant toxicity or allergic reactions in normal use.

Research notes

Research on this specific ingredient is limited, but it is chemically similar to other safe fatty alcohols. Its safety is supported by general cosmetic ingredient reviews and its widespread use in products.

Common label clues

Typical concentration
1–10%
Regulatory status
Approved for use in cosmetics in the EU, US, and other major markets. The Cosmetic Ingredient Review (CIR) panel has evaluated similar fatty alcohols as safe for topical use.
Common uses
Moisturizers, Lip products, Hair conditioners, Makeup
Environmental note
Derived from renewable plant sources, but the hydrogenation process may involve catalysts. Overall, it is considered more sustainable than petroleum-based emollients.

Good to know

  • This ingredient is often used in 'natural' or 'plant-based' formulations because it's derived from vegetable oils.
  • It's a fatty alcohol, not a drying alcohol like SD alcohol or denatured alcohol.
