Glycol Butylene Glycol Montanate

INCI: Glycol/Butylene Glycol Montanate

A gentle wax ester that gives products a smooth, non-greasy feel and helps stabilize formulas.

In plain English

This ingredient is a wax-like substance made from montan wax, a natural fossil wax. It's processed to be more stable and mixable with other ingredients. In skincare and makeup, it helps create a smooth, creamy texture and can make products feel silky without being oily. It also helps keep the product from separating or melting in warm conditions.

Quick decision guide

Useful, but context matters

Glycol Butylene Glycol Montanate 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 Glycol Butylene Glycol Montanate.
  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 semi-synthetic wax ester created by reacting montan wax with glycols and butylene glycol. Montan wax is a natural fossil wax mined from certain types of lignite (brown coal). The resulting ingredient is a hard, brittle wax that melts at a relatively high temperature.

How it works

When added to a cosmetic formula, it acts as an emollient by forming a thin, smooth film on the skin that helps soften and condition. It also increases the viscosity (thickness) of the product, helping to stabilize emulsions and prevent oil and water from separating. In stick products like lipsticks, it provides structure and helps the product hold its shape.

Pros

Non-greasy feel

Provides a smooth, silky texture without leaving a heavy or oily residue, making it ideal for lip products and lightweight creams.

Good stabilizer

Helps keep emulsions from separating and improves the heat stability of stick products, so your lipstick won't melt in your bag.

Cons and cautions

Fossil-derived

Montan wax is a non-renewable fossil resource, which may be a concern for environmentally conscious consumers.

Limited research

There is not a large body of modern research on this specific ingredient's long-term effects on skin, though it has a history of safe use.

Best for

  • Anyone looking for a non-greasy emollient in lip products or creams
  • People who prefer products with a smooth, silky texture

Use caution if

  • Those with very sensitive skin who react to wax-based ingredients
  • Individuals seeking exclusively plant-based or vegan ingredients (montan wax is a fossil wax)

Usage tips

Use in lip balms and lipsticks for a smooth, non-tacky finish.
Combine with other waxes like candelilla or carnauba to adjust hardness and melting point.
Start with a low concentration (around 1%) and adjust based on desired texture.

Safety summary

Glycol/Butylene Glycol Montanate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential. However, as with any ingredient, individuals with very sensitive skin should patch test first.

Research notes

There is limited published research specifically on this ingredient. Its safety is supported by its long history of use in cosmetics and its similarity to other well-studied wax esters. The Cosmetic Ingredient Review (CIR) has not published a specific monograph for this ingredient, but related wax esters are generally considered safe.

Common label clues

Typical concentration
0.5% to 5%
Regulatory status
Generally recognized as safe for use in cosmetics in the US and EU when used as intended. No specific restrictions beyond standard cosmetic ingredient regulations.
Common uses
Lipsticks, Lip balms, Creams, Lotions, Stick products
Environmental note
Montan wax is a fossil resource, meaning it is non-renewable. Its extraction involves mining, which has environmental impacts. Some consumers may prefer plant-based wax alternatives.

Good to know

  • Montan wax is sometimes called 'lignite wax' because it comes from brown coal.
  • This ingredient is often used in combination with other waxes and oils to achieve the right consistency.
