When it comes to formulating home and personal care products, two things are always key: sustainability and performance. HARKE UK & Ireland is proud to spotlight not one, but two suspension agents from Syensqo that deliver on both fronts. Rheozan® BLC and Rheozan® BLC W are designed to enhance formulation aesthetics, stability, and eco-credentials across home and personal care.
So whether you’re looking to suspend fragrance capsules in concentrated laundry detergents, add visual cues to dishwash liquids, or keep exfoliating beads suspended in facial cleansers, these ingredients open the door to cleaner, more creative formulations.
Rheozan® BLC for Home Care
What is Rheozan® BLC?
Rheozan® BLC is a natural and readily biodegradable suspension aid, designed specifically for home care formulations. This ready-to-use liquid polymer is derived from bacterial cellulose produced through a controlled biosynthesis process. Once incorporated into aqueous formulations, its ultra-fine cellulose fibres form a 3D entangled network that delivers superior suspension without affecting flow viscosity.

Benefits of Rheozan® BLC
- Superior Suspension: Maintains stable suspension at low loading (~500 ppm), perfect for fragrance capsules in detergents or particles in spray emulsions.
- Formulation Flexibility: Works across a broad pH range, enzyme-compatible, and easy to use in liquid form with low-energy mixing.
- Eco-Friendly: Readily biodegradable and microplastic-free, aligning with EU sustainability regulations, making it a forward-thinking choice for brands committed to environmental responsibility.
Key Applications
- Laundry Detergents
- Hand Dish Wash
- Toilet Bowl Cleaners
- Laundry Sanitizers
Rheozan® BLC W for Personal Care
What is Rheozan® BLC W?
Rheozan® BLC W brings the same powerful suspension technology to personal care. Produced through biosynthesis using bacterial fermentation of starch, this COSMOS-approved rheology agent consists of ultra-fine cellulose fibres that create a 3D entangled network in aqueous surfactant formulations. The result is exceptional suspension of actives, particles, and other insoluble ingredients – without altering viscosity or compromising skin feel.

Benefits of Rheozan® BLC W
- Powerful Yet Gentle: Delivers high suspension power at low usage levels, with minimal impact on foam or skin feel.
- Eco-Conscious Choice: 100% natural, microplastic-free, COSMOS-approved and readily biodegradable. Its circular design supports water quality and marine life.
- Formulation Versatility: Stable across a wide pH range and suitable for both leave-on and rinse-off formulations, it is ideal to replace synthetic acrylates/copolymers.
Key Applications
- Shampoos
- Body washes
- Liquid hand soaps
- Facial cleansers
