Ingredient review
Hydrogenated Laneth-5
INCI: Hydrogenated Laneth-5
Hydrogenated Laneth-5 is a gentle, lanolin-derived emollient that helps soften skin and stabilize mixtures of oil and water, but it may not suit those with lanolin allergies.
In plain English
Hydrogenated Laneth-5 is a modified version of lanolin, a natural oil from sheep's wool. It's processed to be less sticky and more stable, so it works well in creams and lotions to make skin feel smooth and soft. Think of it as a helper ingredient that blends oils and water together while also moisturizing your skin.

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
Hydrogenated Laneth-5 is a semi-synthetic ingredient made by chemically modifying lanolin (a waxy substance from sheep's wool) through a process called hydrogenation. This makes it more stable, less likely to cause irritation, and easier to use in modern skincare formulas.
How it works
In a cosmetic product, Hydrogenated Laneth-5 acts as both an emollient and an emulsifier. As an emollient, it fills in the tiny gaps between skin cells, making the skin feel smoother and softer. As an emulsifier, it helps oil and water mix together so the product stays creamy and doesn't separate.
Pros
Gentle emollient
Hydrogenated Laneth-5 softens skin without the heavy, sticky feel of raw lanolin, making it comfortable for daily use in moisturizers.
Formula stabilizer
It helps keep oil and water mixed together, so your cream or lotion stays smooth and doesn't separate over time.
Cons and cautions
Not for lanolin allergies
Because it's derived from lanolin, people with wool or lanolin sensitivities may experience redness or irritation.
Not vegan-friendly
This ingredient comes from sheep's wool, so it's not suitable for vegan or strict vegetarian skincare routines.
Best for
- People with dry or normal skin looking for a gentle emollient
- Anyone using creams or lotions who wants a stable, non-greasy texture
Use caution if
- Individuals with known lanolin allergies or sensitivities
- Those seeking vegan or cruelty-free skincare options
Usage tips
Safety summary
Hydrogenated Laneth-5 is considered safe for most people when used in cosmetics. The hydrogenation process reduces the risk of irritation compared to raw lanolin, but individuals with known lanolin allergies should avoid it. No significant toxicity or carcinogenicity concerns have been reported in cosmetic use.
Research notes
Research on Hydrogenated Laneth-5 is limited, but it is generally recognized as safe by cosmetic ingredient review panels. Studies on lanolin derivatives show they are effective emollients with low irritation potential, though individual sensitivity varies.
Common label clues
- Typical concentration
- Typically 0.5% to 5% of the formula
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) with no specific concentration restrictions, but formulators typically use it at low levels.
- Common uses
- Moisturizers, Creams, Lotions, Lip products
- Environmental note
- Lanolin is a byproduct of the wool industry, so its use may raise concerns for those avoiding animal-derived ingredients, but it is a renewable resource.
Good to know
- Hydrogenation makes lanolin less likely to cause allergic reactions, but it's not completely risk-free for sensitive individuals.
- This ingredient is often found in rich creams and lip balms where a smooth, non-greasy feel is desired.
