Description
Glyceryl Stearate – Co-emulsifier, Consistency Agent, Structural Emollient
Glyceryl Stearate also known as Glycemul, is a high-performance co-emulsifier of 100% plant origin that functions as a non-ionic lipophilic co-emulsifier, texturizing agent, and consistency factor for Oil-in-Water (O/W) and Water-in-Oil (W/O) emulsions. Since it is not a standalone emulsifier, it is used only in combination with other emulsifiers, providing emulsions with a rich structure, a glossy white appearance, and high stability.
When combined with a high-HLB emulsifier, it participates in the formation of a lamellar liquid crystal gel network in the external water phase. This three-dimensional network mechanically traps oil droplets and immobilizes free water, significantly increasing the dynamic viscosity of the emulsion and preventing phase separation caused by creaming or coalescence. By reducing lipid crystal size, glyceryl stearate prevents the glassy or grainy texture typical of dense creams, ensuring a smooth, homogeneous, and creamy texture over time.
From a dermatological perspective, as a biomimetic substance, glyceryl stearate transiently integrates into the lipid matrix of the stratum corneum. Its application helps restore the integrity of the hydrolipidic barrier, reducing transepidermal water loss (TEWL) without exerting an occlusive effect.
Ingredients (INCI): Glyceryl Stearate.
Technical Characteristics
- Ingredient Type: Non-ionic lipophilic monoester, non-self-emulsifying type (non-SE).
- Appearance: Granulated powder, cream-white color, neutral odor.
- HLB Value: ~3.8 (strongly lipophilic character).
- Solubility: Soluble in oils and esters upon heating.
- Indicative Dosage: 1% - 10%
Main Properties
- Stabilizer and Co-emulsifier: Strengthens the bond between phases in O/W emulsions and optimizes the performance of the primary emulsifier.
- Consistency Factor: Increases cream density and body, allowing viscosity adjustment of the oil phase.
- Appearance Enhancer: Imparts a clean, optically pleasing opacity with a glossy finish to emulsions.
- Sensory Modifier: Alleviates the overly watery or excessively greasy feel of certain formulas, leaving a velvety, non-greasy film. Ensures smooth, soft-touch creams with a superior sensory profile.
Applications
- Moisturizing, nourishing, and anti-aging facial day and night creams for all skin types.
- Body lotions, body butters, fluid emulsions, and body milks.
- Hair conditioners, hair masks, and conditioning treatments.
- Creamy makeup products, deodorants, self-tanners.
- Baby skin care products, hygiene products.
- Sun care products and after-sun emulsions.
Formulation Guide
- Procedure: Glyceryl Stearate is added to the oil phase of emulsions and requires heating to 65°C - 70°C.
- Need for an Emulsifier: Because its HLB value is low, it cannot form a stable O/W emulsion on its own. It must always be combined with a strong hydrophilic emulsifier (high HLB).
- Formulations: Can be used in non-ionic, anionic, or cationic O/W emulsions, as well as in W/O emulsions; can be used as a binder in anhydrous applications such as lipsticks and balms.
- Recommended Usage Dosage: 1% - 10%. Used at 1% - 5% as a secondary agent in fluid creams and lotions, and up to 5% - 10% in dense creams or balms.
- pH Stability: Optimal within the pH range of 4.5 – 9.0.
Frequently Asked Questions (FAQ)
What is the difference between Glyceryl Stearate and Glyceryl Stearate SE?
The difference lies in self-emulsifying capacity. The plain version consists exclusively of a lipophilic monoester and contains no active hydrophilic components. The "SE" (Self-Emulsifying) version - available in our range under the name Bella Emulsifier - contains a small percentage of integrated surfactant, allowing it to emulsify water and oil mixtures on its own without additional emulsifiers.
Why did my cream separate a few hours after cooling, even though I used glyceryl stearate?
This happens if Glyceryl Stearate was used as the sole emulsifying agent. Due to its low HLB, it lacks the force needed to keep oil droplets dispersed within a large water phase. Without being paired with a high-HLB emulsifier, the phases will separate rapidly. Ensure you use a correctly paired, stable emulsification system.
Safety in Use and Storage
Safety Profile: Safe, non-irritating, biodegradable raw material. Exhibits high dermatological compatibility and is tolerated even by sensitive skin at recommended dosages.
Precautions: For external cosmetic use only.
Storage: Keep in a tightly closed container, in a dry, cool place (below 25°C).

T
Guter Emulgator, ich habe verschiedene Emulgatoren bestellt und bin mit den meisten zufrieden.
A
I'm trying to see what I get, I like to experiment. And I want to get light creams that spread well
A
A good co-emulsifier, which helps the stability of the emulsions (helps a lot in body butters to reduce the greasy feeling, on the skin and beyond) it acts as a lubricant, leaving the skin soft and velvety. It can NOT be replaced with Bella, even if they have similar INCI, they are NOT the same thing. They each work differently.
C
I often use it in combination with an emulsifier , sometimes also with beeswax ,for the preparation of face and décolleté creams .It gives elegant, silky textures and helps moisturize the skin.
L
I use it in quite a large amount , along with a small amount of Olliva and Stearic Acid , for super light creams . I don't feel that film like with other emulsifiers, I think it's great for oily skin.
K
Jeg synes egentlig ikke jeg har bemærket den store emulgerende effekt af glycemul, men den giver en god tekstur i det færdige produkt, og det har jo også betydning.
R
I am very satisfied with this co-emulsifier. I use it in face creams, it gives a silky and velvety feel to the skin, my customers are much happier with the cream than when I use it in the formulation,
L
Works great for face cream. It has a less oily effect when applied to the skin. Ideally combines oil and water!!!
N
I really liked the texture and stability of the creams obtained using this emulsifier. I highly recommend!
C
The Glycemul is A wonderful co emulsifer for oily skin and mix skin. It s perfect in cosmetics for stability for all emulsions and it s not oily ! For the moment I use it in mask with clay, spiruline, vegetable oils and others ingredients. My skin is very well moistured. Thank you
C
I use glycerin stearate in shampoo. When glyceryl stearate is added to shampoos, the hair becomes softer and more beautiful after application. I recommend for all products where you want to achieve greater hydration.
D
I have used this product in the preparation of body butters and was pleased with the result. I recommend.
L
In some formulas it reduces the feeling of oiliness on the skin, it is suitable for all skin types, it can also be used in formulas for the eye area or for sensitive skin
D
It is an indispensable emulsifier in my products. I use it especially for hand cream because it absorbs quickly.
F
The creams are absorbed quickly into the skin.The skin stays moisturized for a longer duration, In masks, it is very good.
I
I use it to increase the stability of emulsions and to get nice textures. It gives good results. Recommendation.
