Primary Functions

1. Emulsification:

• Helps create stable oil-in-water (O/W) emulsions by blending oil and water phases.

• Prevents separation of the oil and water components over time.

2. Stabilization:

• Provides stability to emulsions, ensuring a smooth, uniform texture.

• Reduces the risk of phase separation in lotions, creams, and other emulsified products.

3. Skin Conditioning:

• Acts as a mild emollient, leaving the skin soft and smooth.

• Reduces the greasy feel of formulations by improving spreadability.

4. Thickening Agent:

• Adds viscosity to formulations, resulting in a creamier and more luxurious texture.

Common Applications

1. Moisturizers and Lotions:

• Used to create lightweight and hydrating formulations for daily skincare.

2. Creams:

• Found in thicker formulations like anti-aging creams, night creams, or body creams.

3. Sunscreens:

• Stabilizes emulsions and improves the spreadability of sunscreens.

4. Hair Care Products:

• Used in conditioners and hair masks to enhance texture and consistency.

5. Makeup Products:

• Included in foundations, primers, and BB creams for a smooth and uniform application.

Benefits in Formulations

• Ease of Use: Readily disperses in heated oil or water phases, making it simple to incorporate into formulations.

• Versatility: Compatible with a wide range of oils, butters, and active ingredients.

• Skin-Friendly: Non-irritating and suitable for sensitive skin.

• Cost-Effective: Offers excellent performance at relatively low usage levels (typically 2–5%).

Typical Usage Levels

• 2–5% of the total formulation, depending on the desired stability and texture.

Storage: Protected from direct light and humidity at a temperature of 50°-77°F (10°-25°C)
