Myristyl Glucoside

INCI: Myristyl Glucoside

A mild, non-stripping surfactant that effectively cleanses while being gentle enough for sensitive and dry skin types.

In plain English

Myristyl Glucoside is a cleansing ingredient made from myristyl alcohol (a fatty alcohol) and glucose (a sugar). It belongs to a class of surfactants known as alkyl glucosides, which are known for being very gentle on the skin. Unlike harsher detergents like sodium lauryl sulfate, this ingredient cleanses without stripping away the skin's natural moisture barrier, making it a popular choice for sensitive skin formulas. It helps create a light foam that rinses away dirt, oil, and makeup, leaving skin feeling clean but not tight or dry.

Quick decision guide

Easy yes for most routines

Myristyl Glucoside 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 Myristyl Glucoside.
  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

Myristyl Glucoside is a non-ionic surfactant produced by reacting myristyl alcohol (derived from coconut or palm oil) with glucose (from corn or other plant starches). It is part of the alkyl glucoside family, which are known for their mildness and biodegradability.

How it works

As a surfactant, Myristyl Glucoside works by reducing the surface tension between water and oil, allowing them to mix. This helps lift dirt, sebum, and makeup from the skin so they can be rinsed away with water. Because it is non-ionic, it does not carry a charge and is less likely to irritate or disrupt the skin's protective barrier compared to ionic surfactants.

Pros

Extremely gentle on skin

Myristyl Glucoside is one of the mildest surfactants available, making it ideal for daily use on sensitive or compromised skin without causing dryness or irritation.

Environmentally friendly profile

It is biodegradable and typically derived from plant-based sources, which appeals to eco-conscious consumers looking for sustainable beauty ingredients.

Cons and cautions

Limited cleansing power alone

For heavy makeup or waterproof products, Myristyl Glucoside may need to be paired with other surfactants or oils to achieve thorough removal, which can complicate formulas.

Potential palm oil sourcing

The myristyl alcohol used may come from palm oil, which has environmental concerns unless sourced from certified sustainable plantations.

Best for

  • People with sensitive, dry, or easily irritated skin
  • Those looking for a sulfate-free cleanser

Use caution if

  • Individuals with a known allergy to coconut-derived ingredients (rare)

Usage tips

Use in rinse-off products like cleansers and body washes for best results; it is not typically used in leave-on products.
If you have very oily skin, look for a cleanser that combines Myristyl Glucoside with a slightly stronger surfactant for a deeper clean.

Safety summary

Myristyl Glucoside is considered very safe for topical use. It has a low irritation and comedogenic risk, making it suitable for sensitive and acne-prone skin. No significant safety concerns have been reported in cosmetic use.

Research notes

Alkyl glucosides, including Myristyl Glucoside, have been studied for their mildness and low skin irritation potential. Research supports their use as gentle alternatives to traditional anionic surfactants, with good biodegradability and skin compatibility.

Common label clues

Typical concentration
1–10% in rinse-off products
Regulatory status
Approved for use in cosmetics in the EU, US, and many other regions. The Cosmetic Ingredient Review (CIR) panel has deemed alkyl glucosides safe as used in rinse-off products.
Common uses
Facial cleansers, Body washes, Shampoos, Makeup removers
Environmental note
Myristyl Glucoside is biodegradable and typically derived from renewable plant sources. However, if the myristyl alcohol comes from palm oil, look for RSPO-certified sources to ensure sustainable practices.

Good to know

  • Myristyl Glucoside is often found in 'sulfate-free' and 'gentle' cleansers alongside other alkyl glucosides.
  • It is considered safe for use in cosmetics by major regulatory bodies, including the Cosmetic Ingredient Review (CIR) panel.
