Hydrogenated Mineral Oil

INCI: HYDROGENATED MINERAL OIL

A reliable, non-irritating occlusive that locks in moisture, but may feel heavy on oily or acne-prone skin.

beautyskincareocclusive

In plain English

Hydrogenated mineral oil is a thicker, more stable version of regular mineral oil. It sits on top of your skin like a protective blanket, preventing water from evaporating. This makes it great for very dry skin, but it can feel greasy and might clog pores for some people.

Quick decision guide

Useful, but context matters

Hydrogenated Mineral Oil 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 Mineral Oil.
  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 (saturated with hydrogen) derivative of mineral oil, turning it from a liquid into a semi-solid wax-like substance. It is a purified mixture of hydrocarbons derived from petroleum.

How it works

It forms a thin, non-porous film on the skin's surface that physically blocks water loss (transepidermal water loss or TEWL). This occlusion helps repair the skin barrier and keeps the skin hydrated.

Pros

Superior moisture lock

Creates a strong barrier that dramatically reduces water loss, making it ideal for dry or winter-damaged skin.

Gentle and non-irritating

Rarely causes stinging or allergic reactions, so it's a safe choice for sensitive or reactive skin types.

Cons and cautions

Heavy, greasy feel

The thick texture can feel uncomfortable on the skin, especially under makeup or in humid weather.

Potential for clogged pores

While comedogenic rating is low, some users with acne-prone skin report breakouts from heavy occlusives like this.

Best for

  • People with very dry or dehydrated skin
  • Those with a compromised skin barrier (e.g., eczema, irritation)

Use caution if

  • Individuals with oily or acne-prone skin who find occlusives too heavy

Usage tips

Apply to damp skin to trap extra moisture.
Use only a pea-sized amount for the face to avoid a heavy layer.
Layer over a water-based serum or moisturizer for best hydration.
Avoid using on active acne or broken skin unless directed by a dermatologist.

Safety summary

Hydrogenated mineral oil is considered safe for cosmetic use with a very low irritation profile. The main concerns are cosmetic (texture, pore-clogging potential) rather than health-related. It is non-comedogenic for most people but may not suit very oily skin.

Research notes

Research confirms its effectiveness as an occlusive agent, significantly reducing TEWL. Safety reviews by the Cosmetic Ingredient Review (CIR) panel have deemed it safe for use in cosmetics. No strong evidence links cosmetic-grade mineral oil to cancer or other serious health issues.

Common label clues

Typical concentration
1% to 30% depending on formulation
Regulatory status
Approved for cosmetic use globally, including by the FDA (US) and EU CosIng database. Considered safe at typical concentrations.
Common uses
Moisturizers, Lip balms, Baby oils, Ointments
Environmental note
Derived from petroleum, a non-renewable resource. However, it is a highly refined byproduct and does not contribute to deforestation like some plant oils.

Good to know

  • Hydrogenation makes mineral oil more stable and less likely to spread into a thin layer than liquid mineral oil.
  • It is often used in lip balms and ointments because it stays put and doesn't melt easily.
