Introduction

Quaternium-18 Hectorite is a commonly used ingredient in the cosmetics industry known for its gelling, thickening, and stabilizing properties. This mineral-derived compound is a modified clay that enhances the texture and application of a variety of cosmetic products, thereby improving consumer experiences.

Properties of Quaternium-18 Hectorite

Quaternium-18 Hectorite is a clay-based compound that is modified with quaternary ammonium. It is characterized by its ability to swell in water, create stable suspensions, and increase viscosity. Its unique properties include:

• Viscosity range: 2,000 to 10,000 cP (centipoise)
• Swelling capacity: High, with a water absorption index of 500%
• Thixotropic behavior: Exhibits shear-thinning properties critical for formulation stability
• Cation exchange capacity: 1.0 to 1.5 meq/g

Uses in Cosmetics

Quaternium-18 Hectorite is incorporated into a range of cosmetic products for its thickening and stabilizing abilities. It is particularly beneficial in the following applications:

• Facial creams and lotions: Enhances texture and aids in the suspension of active ingredients.
• Foundations and concealers: Provides smooth application while preventing the settling of pigments.
• Hair care products: Improves the consistency of shampoos and conditioners, ensuring even distribution.
• Eye makeup: Stabilizes mascaras and eyeliners while maintaining product efficacy and wearability.

Hemings Company Solutions

Hemings Company has developed a range of cosmetic solutions incorporating Quaternium-18 Hectorite designed to optimize product performance. Their innovative formulations include:
