🌱 What is Glycerol Monostearate (GMS)?

Glycerol Monostearate, also known as GMS, is a waxy, white, odorless compound derived from glycerin and stearic acid. It is primarily used in cosmetic and food formulations as:

• An emulsifier – helps oil and water mix

• A thickener – gives body and creaminess to formulas

• A stabilizer – prevents ingredients from separating over time

• A skin-conditioning agent – adds a soft, smooth finish

In skincare, GMS plays a pivotal role in texture, stability, and feel—making your creams not just effective, but also delightful to apply.

✅ Why Use GMS in Facial Cream and Lotion Formulation?

Imagine formulating a beautiful cream with rich oils and hydrating ingredients, only to find it separates after a week, or feels sticky, or leaves a waxy residue. Not ideal, right?

That’s where GMS steps in. It works behind the scenes to:

• Create a stable emulsion between oil and water

• Provide a luxurious, non-greasy feel

• Enhance skin absorption of actives

• Improve product shelf life and consistency

If you’re building a facial cream that’s meant to look professional, feel silky, and work effectively, GMS is an absolute must.

🌟 Top Benefits of GMS in Skincare Products

1. 🧴 Acts as a Powerful Emulsifier

GMS is one of the most commonly used emulsifiers in cosmetics. It helps bind oil and water phases, creating a uniform, smooth emulsion that doesn’t split or separate.

This makes your product:

• More stable

• Easier to store

• Professional in appearance and consistency

2. 💧 Improves Moisture Retention

GMS has humectant properties, meaning it attracts moisture to the skin. It helps:

• Maintain hydration

• Prevent dryness and flaking

• Keep skin feeling plump and nourished

3. 🌿 Gives a Smooth, Silky Texture

Thanks to its thickening abilities, GMS adds a lightweight creamy consistency to your product. It absorbs well into the skin and doesn’t leave behind a heavy or greasy residue.

Perfect for both:

• Day creams

• Lightweight moisturizers

4. 🔐 Stabilizes and Extends Product Shelf Life

GMS helps improve the stability of your formulation by:

• Preventing ingredient separation

• Reducing chances of spoilage

• Enhancing preservative performance

This means your product lasts longer without compromising performance or safety.

5. 🧬 Enhances Delivery of Active Ingredients

When blended correctly, GMS improves the spreadability and absorption of other ingredients, allowing actives like Vitamin C, Niacinamide, or Hyaluronic Acid to penetrate more effectively into the skin.

🧴 How to Use GMS in Cream or Lotion Formulations

✅ Recommended Usage Rate:

Note: Start with lower concentrations for lightweight products like facial moisturizers and increase for thicker formulations like body butters.

✅ How to Incorporate GMS:

• Add to the oil phase of your formulation

• Heat to melt (around 65–70°C)

• Blend with water phase to emulsify

• Cool and add heat-sensitive ingredients

📌 GMS works best with other emulsifiers or co-emulsifiers (like Cetyl Alcohol or Stearic Acid) for improved stability.

✅ Compatible Skincare Ingredients:
