    Butylene Glycol CAS 107-88-0

    Butylene Glycol (CAS 107-88-0), chemically identified as 1,3-butanediol, is a high-purity aliphatic diol functioning as a superior humectant and solvent in cosmetic skin care formulation and topical pharmaceutical vehicles. This clear, odorless, and viscous liquid, widely technically recognized for its antimicrobial properties, acts to decrease viscosity and prevent the drying out of products, serving as a safer, less irritating alternative to Propylene Glycol in hypoallergenic serums, sheet masks, and herbal extracts. We provide bulk supply of this cosmetic grade ingredient with competitive factory pricing to ensure formulation safety for personal care brands. Our production process guarantees strict control over residual ketones, making MSDS, TDS, COA available alongside customized specifications to meet global cosmetic compliance standards.

    Applications

    1. Cosmetics & Personal Care

    • Humectant and moisturizing agent in lotions, creams, serums, masks and cleansers
    • Solvent and carrier for preservatives, actives and fragrances
    • Viscosity modifier and freeze-thaw stabilizer in water-based formulations
    • Helps improve skin feel and reduces tackiness of high-glycerin systems

    2. Home & Industrial Cleaners

    • Solvent and coupling agent in water-based cleaners and detergents
    • Improves stability and clarity of surfactant systems

    3. Industrial & Chemical Uses

    • Intermediate in the synthesis of plasticizers, resins and specialty chemicals
    • Auxiliary solvent in ink, coating and adhesive formulations

    4. Flavor & Food-Related Uses

    • Listed as a flavoring substance and solvent in some flavor applications (subject to local food regulations and purity requirements).

    For detailed application discussion or formulation advice, please email info@industrochem.com with your end-use and target specifications.

    Storage Conditions

    • Store in a cool, dry, well-ventilated warehouse, away from direct sunlight and heat sources.
    • Recommended storage temperature: 5–30 °C.
    • Keep containers tightly closed; product is hygroscopic and can absorb moisture from air.
    • Keep away from strong oxidizing agents, acid chlorides, acid anhydrides and strong reducing agents.

    Under proper storage conditions, shelf life is typically 12–24 months in original unopened packaging.

    Safety Precautions

    • Generally considered to have low acute toxicity; however, direct contact may cause mild eye or skin irritation.
    • Avoid breathing mists; use local exhaust ventilation in large-scale operations.
    • Wear safety goggles, protective gloves and protective clothing during handling.
    • In case of eye contact: rinse cautiously with water for several minutes; seek medical attention if irritation persists.
    • In case of skin contact: wash with soap and water.
    • Spills: contain and absorb with inert material (sand, diatomite), then collect in suitable containers for disposal.
    • Although the flash point is relatively high, Butylene Glycol is still a combustible organic liquid – keep away from open flames, hot surfaces and sources of ignition.

    FAQ - Technical & Supply Chain

    • Q:

      How does the solvent capability of Butylene Glycol (CAS 107-88-0) enhance the efficacy of botanical extraction processes?

      A: Due to its unique polarity profile, this diol effectively penetrates plant cellular structures to dissolve and extract a wider range of active phytochemicals than water alone, while simultaneously acting as a carrier that prevents the extracted actives from precipitating out of the final solution.
    • Q:

      In terms of formulation preservation, what secondary benefit does this humectant provide beyond hydration?

      A: When incorporated at concentrations generally above 5%, Butylene Glycol exhibits significant bacteriostatic activity; this property allows formulators to reduce the dosage of traditional, potentially irritating preservatives (like parabens or phenoxyethanol) while maintaining the product's microbiological stability.
