Ingredient review
PEG-50 Hydrogenated Tallow Amine
INCI: PEG-50 Hydrogenated Tallow Amine
A synthetic emulsifier that helps mix oil and water, but may be irritating for sensitive skin and has moderate comedogenic potential.
In plain English
PEG-50 Hydrogenated Tallow Amine is a man-made ingredient that helps oil and water blend together in products like shampoos and cleansers. It is made from hydrogenated tallow (a processed animal fat) combined with polyethylene glycol (PEG). While it works well as a cleanser and emulsifier, it can be drying or irritating for some skin types, especially if used in high concentrations or left on the skin.

Quick decision guide
Useful, but context matters
PEG-50 Hydrogenated Tallow Amine can be useful, but watch for some irritation potential and possible clogging concerns.
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 PEG-50 Hydrogenated Tallow Amine.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
Clogging risk
moderateMay be fine for many users but deserves caution if you are breakout-prone.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic surfactant and emulsifier created by reacting hydrogenated tallow (a processed animal fat) with polyethylene glycol (PEG). It belongs to a class of ingredients called ethoxylated amines, which help reduce surface tension between oil and water.
How it works
In a cosmetic product, PEG-50 Hydrogenated Tallow Amine acts as a surfactant, meaning it helps water and oil mix together. It also has mild conditioning properties, which is why it is sometimes used in hair products to reduce static and improve manageability. In cleansers, it helps lift dirt and oil from the skin or hair so they can be rinsed away.
Pros
Effective emulsifier
Helps create stable, well-mixed formulas so products don't separate, improving the user experience.
Mild conditioning
Provides light conditioning in hair products, reducing frizz and making hair easier to comb without heavy buildup.
Cons and cautions
Potential irritation
Can cause stinging, redness, or dryness for sensitive skin, especially in high concentrations or leave-on products.
Moderate comedogenic risk
May clog pores for some people, potentially leading to breakouts, so it is not ideal for acne-prone skin.
Best for
- People with normal to oily skin looking for effective cleansing
- Those using rinse-off products like shampoos or body washes
Use caution if
- Individuals with sensitive, dry, or acne-prone skin
- Vegans or those avoiding animal-derived ingredients
Usage tips
Safety summary
Generally considered safe for use in rinse-off cosmetics at typical concentrations. However, it may cause irritation for sensitive individuals and has a moderate comedogenic rating. Those with acne-prone or reactive skin should approach with caution. The ingredient is not recommended for leave-on products due to potential irritation and pore-clogging risk.
Research notes
Limited direct research on PEG-50 Hydrogenated Tallow Amine specifically. Studies on similar ethoxylated amines indicate they can be mild irritants, especially at higher concentrations. The Cosmetic Ingredient Review (CIR) panel has reviewed related PEG tallow amines and found them safe for rinse-off use with concentration limits, but no specific review for this exact ingredient was identified.
Common label clues
- Typical concentration
- Usually 0.5% to 5% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The EU restricts the use of certain ethoxylated amines due to potential impurity concerns, but PEG-50 Hydrogenated Tallow Amine is not specifically banned.
- Common uses
- Cleansers, Shampoos, Conditioners, Hair dyes
- Environmental note
- Derived from animal fat (tallow), which is a byproduct of the meat industry. The PEG manufacturing process may involve ethylene oxide, which is energy-intensive and has environmental considerations.
Good to know
- PEG-50 Hydrogenated Tallow Amine is not commonly found in natural or 'clean' beauty products due to its synthetic origin and animal-derived source.
- The number '50' refers to the average number of ethylene oxide units in the PEG chain, which affects its water solubility and mildness.
