Lotte HECELLOSE B-30K Hydroxyethyl Cellulose – Frequently Asked Questions (FAQ)

Q1: What is the primary functional role of Lotte HECELLOSE B-30K in aqueous formulations?

A: Lotte HECELLOSE B-30K functions primarily as a non-ionic water-soluble thickener and rheology modifier. It imparts pseudoplastic flow behavior, improves suspension stability, and enhances film-forming capability without significantly affecting pH or ionic strength sensitivity.

Q2: How does Lotte HECELLOSE B-30K compare to other hydroxyethyl cellulose grades in terms of viscosity performance?

A: As a medium-viscosity grade, B-30K offers balanced thickening efficiency and ease of incorporation—higher than low-MW grades but more manageable than ultra-high-viscosity HECs. Its solution viscosity develops rapidly upon hydration and remains stable across a broad pH range (typically 3–11).

Q3: Is Lotte HECELLOSE B-30K compatible with common preservatives and surfactants used in personal care products?

A: Yes, B-30K demonstrates good compatibility with a wide range of anionic, non-ionic, and amphoteric surfactants, as well as commonly used preservative systems—including parabens, isothiazolinones, and formaldehyde donors—without causing phase separation or viscosity loss under typical formulation conditions.

Q4: What are the recommended handling and dispersion practices to avoid clumping during incorporation?

A: To ensure efficient dispersion, it is recommended to pre-mix B-30K with a water-miscible liquid (e.g., glycerin or propylene glycol) or dry-blend with other powdered ingredients before gradual addition to the aqueous phase under moderate shear. Avoid direct addition of dry powder into static water.

Q5: Can Lotte HECELLOSE B-30K be used in applications requiring freeze-thaw stability?

A: While B-30K solutions exhibit reasonable resilience to mild freeze-thaw cycles, long-term or repeated freezing may lead to partial viscosity loss or microgel formation. For demanding freeze-thaw environments, formulation optimization—such as co-use with compatible stabilizers—is advisable.
