Evidence level

moderate

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

What it is

Glyceryl Dimyristate/Hydrogenated Rosinate is a semi-synthetic ester. It is created by combining glycerin, myristic acid (a fatty acid often from plant sources), and hydrogenated rosin (a modified tree resin). This combination results in a versatile ingredient that acts as an emollient, film former, and viscosity controller.

How it works

In a cosmetic product, this ingredient works in a few ways. As an emollient, it softens and smooths the skin by filling in gaps between skin cells. As a film former, it leaves a thin, flexible layer on the skin or lips, helping other ingredients stay in place and improving water resistance. It also helps control the thickness or 'body' of a product, making it easier to apply and more stable.

Pros

Improves product feel

Creates a smooth, silky texture that makes makeup and skincare easier to apply and more comfortable to wear.

Boosts wear time

Helps lipsticks and foundations stay in place longer, reducing the need for frequent touch-ups.

Cons and cautions

Semi-synthetic origin

While derived from natural sources, it undergoes chemical modification, which may not suit those seeking fully natural formulations.

Limited independent research

Most safety data comes from manufacturer studies; long-term independent research on skin is not extensive.

Best for

Anyone looking for long-lasting lip products
People who prefer smooth, creamy foundations and creams

Use caution if

Those strictly avoiding any synthetic or semi-synthetic ingredients
Individuals with known allergies to tree resin derivatives (rare)

Usage tips

Look for this ingredient in lip products for better staying power.

In creams and lotions, it can help create a richer, more luxurious feel without greasiness.

Safety summary

Glyceryl Dimyristate/Hydrogenated Rosinate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. However, as with any ingredient, patch testing is recommended for those with sensitive skin or allergies.

Research notes

Safety assessments by the Cosmetic Ingredient Review (CIR) panel and manufacturer data support its use as a safe cosmetic ingredient. Independent studies are limited, but existing evidence points to low toxicity and skin irritation.

Common label clues

Typical concentration: 0.5% to 5%
Regulatory status: Approved for use in cosmetics in the US (FDA) and EU (CosIng). Generally recognized as safe when used as directed.
Common uses: Lipsticks, Lip balms, Foundations, Creams, Lotions, Sunscreens
Environmental note: The myristic acid component is often derived from coconut or palm oil. Choosing products with sustainably sourced palm oil can reduce environmental impact.

Good to know

Hydrogenated rosin is a modified tree resin, often from pine trees, used to improve film-forming properties.
This ingredient is often used in combination with other emollients to balance texture and feel.
