Polyglyceryl-6 Myristyl Ether

INCI: POLYGLYCERYL-6 MYRISTYL ETHER

A mild, non-irritating emulsifier that helps create stable, lightweight creams and lotions without stripping the skin.

In plain English

Polyglyceryl-6 Myristyl Ether is an emulsifier — think of it as a friendly bridge that helps water and oil mix together in your moisturizer or cleanser. It is made from glycerin (a natural humectant) and myristyl alcohol (derived from plant fats), so it is considered gentle and unlikely to clog pores or cause irritation. Because it is non-ionic (neutral charge), it works well with many other ingredients and can create silky, spreadable textures that feel light on the skin.

Quick decision guide

Easy yes for most routines

Polyglyceryl-6 Myristyl Ether 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 Polyglyceryl-6 Myristyl Ether.
  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

A non-ionic emulsifier created by reacting polyglycerin (a chain of glycerin units) with myristyl alcohol (a fatty alcohol from plant sources like coconut or palm). It belongs to the polyglyceryl ester family, known for being milder than traditional emulsifiers.

How it works

In a formula, it reduces the surface tension between oil and water, allowing them to form a stable, uniform mixture. This prevents the product from separating and gives it a smooth, creamy texture. It also has mild skin-conditioning properties, helping to soften and smooth the skin's surface.

Pros

Gentle on skin

Polyglyceryl-6 Myristyl Ether has a very low irritation score, making it a safe choice for sensitive, eczema-prone, or easily irritated skin types.

Lightweight texture

Unlike some waxy emulsifiers, it creates a silky, non-greasy feel that absorbs quickly, ideal for daytime moisturizers and gel-creams.

Cons and cautions

Potential palm sourcing

Myristyl alcohol is often derived from palm oil, which can be associated with deforestation if not sustainably sourced. Look for RSPO-certified products if this concerns you.

Less studied than classics

Compared to emulsifiers like glyceryl stearate, there is less published research on polyglyceryl-6 myristyl ether's long-term skin effects, though existing data supports its safety.

Best for

  • People with sensitive or reactive skin looking for a gentle emulsifier
  • Anyone who prefers lightweight, non-greasy moisturizers and lotions

Use caution if

  • Those with a known allergy to polyglycerin or myristyl alcohol (rare)

Usage tips

Store products containing this emulsifier in a cool, dry place to maintain emulsion stability.
If you have very dry skin, pair it with richer oils or butters in your routine, as it is lightweight and may not provide enough occlusion alone.

Safety summary

Polyglyceryl-6 Myristyl Ether is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for sensitive skin. No significant safety concerns have been reported in regulatory or dermatological literature.

Research notes

Research on polyglyceryl-6 myristyl ether is limited but consistent with the broader safety profile of polyglyceryl esters, which are well-tolerated and non-irritating. Most evidence comes from ingredient safety databases and formulation studies rather than clinical trials.

Common label clues

Typical concentration
0.5% to 5%
Regulatory status
Approved for use in cosmetics in the EU, US, and most major markets. It is listed in the CosIng database and generally recognized as safe when used as directed.
Common uses
Moisturizers, Cleansers, Serums, Sunscreens
Environmental note
Sourcing of myristyl alcohol may involve palm oil; choosing products with RSPO-certified palm or alternative plant sources can reduce environmental impact.

Good to know

  • Polyglyceryl-6 Myristyl Ether is often used in 'natural' or 'clean' beauty formulations because it is derived from plant-based glycerin and fatty alcohols.
  • It is considered a 'non-ionic' emulsifier, meaning it does not carry a charge, which helps it work well with both acidic and alkaline ingredients.
