INCI: Acetylated Lard Glyceride

A semi-synthetic emollient that softens skin but may clog pores for some, and is not suitable for vegan or certain religious lifestyles.

In plain English

Acetylated Lard Glyceride is a modified fat made from lard (pig fat). In cosmetics, it helps soften and smooth the skin by forming a light, non-greasy film that reduces water loss. Because it comes from an animal source, it is not vegan or suitable for some religious practices. It can be comedogenic for acne-prone skin, so it's best for dry or normal skin types.

Quick decision guide

Useful, but context matters

Acetylated Lard Glyceride can be useful, but watch for possible clogging concerns.

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 Acetylated Lard Glyceride.
  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

moderate

May be fine for many users but deserves caution if you are breakout-prone.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A semi-synthetic ingredient created by reacting lard (rendered pig fat) with acetic acid, resulting in a modified glyceride that is more stable and less greasy than plain lard.

How it works

It sits on the skin's surface as an emollient, filling in gaps between skin cells to create a smoother feel and reduce transepidermal water loss (TEWL, or moisture escaping from the skin). Its acetylated structure makes it lighter and less occlusive than unmodified lard.

Pros

Lightweight emollient

Provides softness without the heavy, greasy feel of traditional lard, making it pleasant in creams and lotions.

Improves product texture

Helps other ingredients spread evenly and gives a silky after-feel, enhancing the user experience.

Cons and cautions

Animal-derived

Sourced from pig fat, so it is not vegan and may conflict with kosher or halal dietary or lifestyle choices.

Moderate comedogenic risk

May clog pores in acne-prone individuals, potentially leading to breakouts if used on oily or congested skin.

Best for

  • People with dry or normal skin looking for a lightweight emollient
  • Those who are comfortable using animal-derived ingredients

Use caution if

  • Vegans and those following kosher or halal practices
  • Acne-prone or oily skin types (moderate comedogenic risk)

Usage tips

Patch test on a small area before widespread use, especially if you have acne-prone skin.
Pair with non-comedogenic ingredients if you have combination skin to reduce pore-clogging risk.
Check product labels if you follow a vegan or religiously observant lifestyle, as this ingredient is not always clearly labeled as animal-derived.

Safety summary

Acetylated Lard Glyceride is generally recognized as safe for cosmetic use. The main concerns are ethical (animal origin) and potential comedogenicity for acne-prone skin. Irritation is rare.

Research notes

The Cosmetic Ingredient Review (CIR) panel has evaluated acetylated lard glyceride and found it safe in current usage practices. No significant human or animal studies show toxicity at cosmetic concentrations.

Common label clues

Typical concentration
Typically 1–10% in leave-on products; higher in wash-off products
Regulatory status
Approved for use in cosmetics in the US (FDA) and EU (CosIng) with no specific restrictions at typical concentrations.
Common uses
Moisturizers, Lip products, Bar soaps, Hair conditioners
Environmental note
Lard is a byproduct of the meat industry, so its use may be considered more sustainable than virgin plant oils by some, but it still relies on animal agriculture.

Good to know

  • Acetylated Lard Glyceride is considered safe by the Cosmetic Ingredient Review (CIR) panel at typical use levels.
  • It is often used in bar soaps to improve lather creaminess and skin feel.
  • The acetylation process reduces the strong odor associated with raw lard.
