PEG-130 Glyceryl Tallowate

INCI: PEG-130 Glyceryl Tallowate

PEG-130 Glyceryl Tallowate is a reliable emulsifier that helps mix oil and water, but its animal-derived origin and PEG processing may raise concerns for some users.

In plain English

This ingredient is a helper that keeps oil and water from separating in your lotions and cleansers. It's made by attaching a polyethylene glycol (PEG) chain to a fat from animal tallow. While it's effective and generally gentle, the use of animal fat and the potential for trace impurities from PEG processing are things to consider.

Quick decision guide

Useful, but context matters

PEG-130 Glyceryl Tallowate 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 PEG-130 Glyceryl Tallowate.
  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

PEG-130 Glyceryl Tallowate is a semi-synthetic emulsifier created by reacting tallow (rendered animal fat) with polyethylene glycol (PEG). The '130' indicates the average number of ethylene oxide units in the PEG chain, which determines its water-loving properties. It is a waxy solid at room temperature and is used to stabilize oil-in-water emulsions.

How it works

In a cosmetic product, this ingredient sits at the boundary between oil and water droplets. Its tallowate part is oil-loving (lipophilic) and embeds into oil droplets, while the long PEG chain is water-loving (hydrophilic) and extends into the water phase. This creates a stable barrier that prevents the two phases from separating, giving your product a smooth, uniform texture.

Pros

Effective emulsifier

It reliably blends oil and water, giving products a smooth, consistent feel that doesn't separate over time.

Low irritation potential

Most skin types tolerate it well, making it a common choice for gentle cleansers and moisturizers.

Cons and cautions

Animal-derived source

It comes from tallow, so it's not suitable for vegans or those who prefer plant-based ingredients.

PEG processing concerns

The manufacturing process can create trace impurities like 1,4-dioxane, though reputable brands purify their ingredients to safe levels.

Best for

  • People who use conventional lotions, creams, or cleansers and want a stable, effective formula
  • Those with normal to dry skin looking for a gentle emulsifier

Use caution if

  • Vegans and those avoiding animal-derived ingredients
  • Individuals concerned about PEG processing and potential trace contaminants

Usage tips

Check the full ingredient list if you follow a vegan or plant-based routine, as this ingredient is animal-derived.
Look for products from brands that test for and limit 1,4-dioxane if you are concerned about PEG processing.

Safety summary

PEG-130 Glyceryl Tallowate is considered safe for use in cosmetics at typical concentrations. The main concerns are its animal origin and the potential for trace impurities from PEG manufacturing, which are regulated and minimized in quality products.

Research notes

Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that PEG compounds are safe when formulated to meet purity standards. No specific studies on PEG-130 Glyceryl Tallowate were found, but its safety profile is inferred from similar PEGylated emulsifiers.

Common label clues

Typical concentration
0.5% to 5%
Regulatory status
Approved for use in cosmetics in the US (FDA) and EU (CosIng) with no specific concentration restrictions, though manufacturers are expected to minimize impurities like 1,4-dioxane.
Common uses
Cleansers, Lotions, Creams
Environmental note
Tallow is a byproduct of the meat industry, so its use can be seen as reducing waste. However, the PEG portion is derived from petroleum, and the ingredient may not be readily biodegradable in aquatic environments.

Good to know

  • The '130' in the name refers to the PEG chain length, which affects how water-loving the molecule is.
  • This ingredient is often used in rinse-off products like cleansers and body washes, where its emulsifying power helps remove oils and dirt.
