Ingredient review
PPG-3 Myristyl Ether Macadamiate
INCI: PPG-3 MYRISTYL ETHER MACADAMIATE
A lightweight, non-greasy emollient that gives skin a silky finish and is generally well-tolerated.
In plain English
PPG-3 Myristyl Ether Macadamiate is a semi-synthetic ingredient made by combining a fatty alcohol (myristyl alcohol) with macadamia oil, then adding a small propylene glycol chain. The result is a lightweight oil that spreads easily on skin, feels silky, and helps lock in moisture without leaving a heavy or sticky residue. It is often used as a silicone alternative in 'clean' beauty formulas.

Quick decision guide
Useful, but context matters
PPG-3 Myristyl Ether Macadamiate 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.
- Step 1Start with the score, then check the irritation and clogging risk before judging PPG-3 Myristyl Ether Macadamiate.
- 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
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
A semi-synthetic ester created from macadamia oil and myristyl alcohol, modified with a short PPG (polypropylene glycol) chain to improve spreadability and skin feel.
How it works
It sits on the skin's surface, forming a thin, breathable film that reduces water loss (transepidermal water loss, or TEWL) while imparting a smooth, velvety texture. Its molecular structure allows it to glide on easily, making it a popular silicone replacer.
Pros
Silky, lightweight feel
It spreads easily and leaves skin feeling smooth and velvety, not sticky or heavy.
Good moisturizer helper
By forming a thin barrier on skin, it helps reduce moisture loss, keeping skin hydrated longer.
Cons and cautions
Semi-synthetic origin
It is chemically modified, so it may not appeal to those seeking 100% natural ingredients.
Limited long-term data
While generally considered safe, there is less published research on this specific ingredient compared to more common emollients.
Best for
- Anyone seeking a lightweight, non-greasy moisturizer
- People who prefer silicone-free formulas
Use caution if
- Those with extremely sensitive skin should patch-test first due to the PPG component
Usage tips
Safety summary
PPG-3 Myristyl Ether Macadamiate is considered safe for topical use at typical concentrations. It has low irritation and comedogenic potential, though individuals with very sensitive skin should patch-test.
Research notes
Safety assessments rely on analogy to similar PPG ethers and esters, which have a long history of safe use. Direct clinical studies on this specific ingredient are sparse, but no significant safety concerns have been reported.
Common label clues
- Typical concentration
- 1–5%
- Regulatory status
- Approved for cosmetic use in the EU, US, and other major markets. No specific restrictions.
- Common uses
- Moisturizers, Serums, Hair conditioners, Lip products
- Environmental note
- Macadamia oil is a renewable resource, but the PPG modification involves synthetic processing. Biodegradability data is limited.
Good to know
- It is often found in 'clean beauty' products as a silicone alternative.
- The PPG chain is short, so it is less likely to cause irritation than longer PPG chains.
