Ingredient review
Zinc Linoleate Hydroxide
INCI: ZINC LINOLEATE HYDROXIDE
A gentle zinc-based ingredient that helps condition skin and provide mild oil control without drying.
In plain English
Zinc Linoleate Hydroxide is a combination of zinc and linoleic acid (an omega-6 fatty acid found in many plant oils). In skincare, it works as a skin conditioner, helping to keep the skin feeling smooth and soft. It also has mild astringent properties, meaning it can help tighten pores and reduce excess oil on the skin's surface. Unlike some stronger astringents, it is generally non-irritating and non-drying, making it suitable for many skin types, including sensitive 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 Zinc Linoleate Hydroxide.
- 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
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic compound formed by reacting zinc with linoleic acid, resulting in a powder that is used in cosmetics for its conditioning and oil-controlling benefits.
How it works
When applied to the skin, Zinc Linoleate Hydroxide forms a thin film that helps retain moisture and smooth the skin's surface. The zinc component provides mild astringent and soothing effects, while the linoleic acid supports the skin's natural barrier function. This combination helps reduce the appearance of pores and control shine without stripping the skin of its natural oils.
Pros
Gentle oil control
Provides a mild astringent effect that helps reduce excess oil and shine without the drying or irritation often caused by stronger ingredients like alcohol or witch hazel.
Skin conditioning
The linoleic acid component supports the skin's natural barrier, helping to keep skin soft and smooth while the zinc soothes.
Cons and cautions
Limited research
There is less published research on this specific compound compared to more common ingredients like niacinamide or salicylic acid, so its full range of benefits is not as well-documented.
Mild effect
For those with very oily or acne-prone skin, this ingredient may not be strong enough on its own to control breakouts or significant shine.
Best for
- People with oily or combination skin looking for gentle oil control
- Those with sensitive skin who want a mild astringent without irritation
Use caution if
- Individuals with very dry or dehydrated skin may find it slightly tightening
Usage tips
Safety summary
Zinc Linoleate Hydroxide is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. As with any ingredient, patch testing is recommended for those with very sensitive skin.
Research notes
Research on Zinc Linoleate Hydroxide specifically is limited, but studies on zinc salts and linoleic acid individually support their roles in skin conditioning and mild astringency. The combination is generally regarded as safe and effective based on cosmetic ingredient safety assessments.
Common label clues
- Typical concentration
- 0.5% to 2%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets as a skin-conditioning agent. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Moisturizers, Serums, Cleansers, Sunscreens
- Environmental note
- Zinc compounds can accumulate in aquatic environments if not properly filtered during manufacturing, but at typical cosmetic concentrations the environmental impact is considered low.
Good to know
- Zinc Linoleate Hydroxide is often used in formulations for sensitive or reactive skin due to its low irritation potential.
- It is not the same as zinc oxide (a mineral sunscreen) or zinc PCA (another zinc salt used for acne).
