Product Overview
Disteardimonium Hectorite (CAS 94891-31-3) is an organically modified hectorite clay used as a cosmetic rheological additive. It delivers consistent thixotropic thickening in medium-to-low polarity systems, including mineral oil, vegetable oil, isododecane, and silicone oils. Unlike unmodified bentonite, it requires a polar activator to develop its full viscosity-building network - this activation step is what separates a stable gel from a settling dispersion.
This grade meets cosmetic specifications with purity ≥99%, moisture ≤3.0%, and microbial content ≤100 cfu/g. Heavy metals (Pb, As, Hg, Cd) are controlled below the China Cosmetic Safety Technical Standard 2015. The natural origin index is 100% (ISO 16128), and the product is non-animal origin - suitable for vegan and clean-label formulas. It shares the same INCI name and CAS number as BENTONE® 38VCG, making it a practical replacement in existing formulations without reformulation. For a step-by-step evaluation framework, see our BENTONE® 38VCG Alternative Guide for Formulators.
Alfa Chemical supplies this product from Zhengzhou, Henan, in 1 kg to 25 kg quantities with batch-specific COA and SDS. Activation guidance with propylene carbonate is available for first trials.

Market Insight
The global Disteardimonium Hectorite market was valued at approximately US$ 62.3 million in 2025 and is projected to reach US$ 99.7 million by 2034, growing at a CAGR of 5.2%. Growth is driven by the expanding clean beauty market, where formulators seek mineral-based rheology modifiers that meet ISO 16128 natural origin standards without compromising on suspension and thickening performance.
The waterless rheology modifiers segment, which includes organoclays, is growing at an even faster pace - a 9.3% CAGR from 2026 to 2036 - as anhydrous formulations gain traction in color cosmetics and sunscreen. Disteardimonium Hectorite sits at the center of this trend, offering a non-animal, naturally derived alternative to traditional thickeners.
Key Properties
Before activating this organoclay in your formulation, check these six properties against your oil phase polarity, target viscosity, and processing equipment. Each affects suspension stability, pigment orientation, or regulatory compliance.
High Thixotropic Thickening
Builds viscosity that recovers after shear. Typical dosage 3–5% in medium-polarity oils. Strong viscosity build in toluene dispersion tests at 2% solids.
Pigment Orientation Control
Prevents color streaking in foundation, lipstick, and mascara. Ensures uniform color payoff by aligning pigment platelets during drying.
Heat & Storage Stability
Prevents phase separation during transport and prolonged storage. Stable at 45°C for 4 weeks in accelerated testing - suitable for summer shipping.
Non-Animal Origin
Mineral-based. Natural Origin Index 100% per ISO 16128. Suitable for vegan and cruelty-free cosmetic lines.
Low Microbial Content
≤100 cfu/g. Helps reduce preservative demand in the final formula. Heavy metals comply with China Cosmetic Safety Technical Standard 2015.
Activator Compatibility
Propylene carbonate recommended at 15–35% based on clay weight. Disperse at 1,000–2,000 rpm for 10–15 minutes until a homogeneous gel forms.
