THE STORY OF FINECHEMO DSTB
Finechemo DSTB: The Classic pH Buffer & Emulsifier Aid
Finechemo DSTB (Sodium Tetraborate) is a multifunctional mineral ingredient used in cosmetics as a pH adjuster, stabilizer, and emulsification helper. Historically used in creams, lotions, bath salts, and personal-care cleansing products, it supports product stability, texture, and mild preservative action in alkaline systems.
Naturally Mined Mineral, Refined for Industrial & Cosmetic Purity
Finechemo DSTB is sourced from natural deposits (most famously in California, Turkey, China) and processed through dissolving, crystallization, and filtration to produce high-purity disodium tetraborate decahydrate or pentahydrate. TRCkem supplies cosmetic and technical grades depending on formulation needs
Stabilize. Buffer. Support Emulsions.
Functional roles in cosmetic & personal-care formulations:
âś… Helps control pH and maintain alkaline stability
âś… Works as aco-emulsifier with fatty acids (e.g., beeswax + borax classic cream system)
âś… Provides softening & water-conditioning effects in bath and cleansing formulas
âś… Offers mild antimicrobial support in high-pH formulas
Traditionally found in: cold creams, cleansing milks, emulsified ointments, bath salts, and soap bars.
Regulated Use – Allowed in Limited Categories OnlyA
Typical usage level:0.1–3%depending on type of emulsion or cleansing system.
Finechemo DSTB is restricted in many regions due to classification as a “reprotoxic” substance at high doses →not permitted in leave-on EU cosmetics, but still used in certain rinse-off and non-skin-contact formulations.
pH range: works best in systems pH 7–9.
Must be stored dry, sealed, away from moisture.
Always check regional regulatory status before use (EU, FDA, ASEAN may vary by category).
