Ingredient review
Sodium Carboxymethyl Tallow Polypropylamine
INCI: SODIUM CARBOXYMETHYL TALLOW POLYPROPYLAMINE
A semi-synthetic surfactant and conditioner from tallow that can improve feel and foam but may be too heavy or irritating for sensitive or acne-prone skin.
In plain English
This ingredient is a modified fat from animal tallow (usually beef) that has been chemically altered to work as a mild cleanser and softener. In shampoos and body washes, it helps create a creamy lather and leaves hair or skin feeling smoother. However, because it is derived from animal fat, it can be heavy and may clog pores or cause irritation for some people.

Quick decision guide
Useful, but context matters
Sodium Carboxymethyl Tallow Polypropylamine 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 Sodium Carboxymethyl Tallow Polypropylamine.
- 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 conditioning agent made by reacting tallow (rendered animal fat) with propylamine and carboxymethyl groups. It is used to improve foam quality and provide a soft, conditioned feel.
How it works
It reduces the surface tension between water and oils, helping to lift dirt and excess sebum. Its conditioning portion deposits a thin film on hair or skin, reducing friction and static, which makes hair easier to comb and skin feel smoother.
Pros
Creamy lather
Creates a rich, stable foam that feels luxurious in shampoos and body washes, improving the sensory experience.
Conditioning effect
Leaves hair and skin feeling softer and less dry compared to harsher surfactants, reducing the need for separate conditioners.
Cons and cautions
Potential pore clogging
Because it is derived from tallow, it can leave a heavy residue that may clog pores and trigger breakouts in acne-prone individuals.
Animal-derived source
Not suitable for vegans or those who prefer plant-based ingredients, and may raise ethical concerns about animal by-products.
Best for
- Those with normal to dry hair looking for extra conditioning
- People who tolerate mild animal-derived ingredients and want a creamy lather
Use caution if
- Vegans and those avoiding animal-derived ingredients
- Acne-prone or oily skin types due to potential pore-clogging
Usage tips
Safety summary
Generally considered safe for most people when used in rinse-off products at typical concentrations. However, it may cause mild irritation or clog pores in sensitive or acne-prone individuals. Not suitable for vegans.
Research notes
Limited peer-reviewed studies specifically on this ingredient. Safety is inferred from its structural similarity to other tallow-based surfactants and conditioning agents, which have been reviewed by cosmetic safety panels (e.g., CIR) as safe for use in cosmetics.
Common label clues
- Typical concentration
- 0.5–5%
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) within typical concentrations. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Shampoos, Conditioners, Body washes, Bar soaps
- Environmental note
- Tallow is a by-product of the meat industry, so its use can be seen as reducing waste. However, animal agriculture has a higher environmental footprint than plant-based alternatives.
Good to know
- Tallow-derived ingredients are common in traditional bar soaps and some drugstore shampoos.
- This ingredient is rarely used alone; it is typically part of a surfactant blend.
