Description

1,3-Butanediol-1-Monooctanoate is a high-purity monoester derivative of 1,3-butanediol and octanoic acid, valued for its role as a versatile intermediate and functional ingredient. Its balanced hydrophobic-lipophilic character makes it an effective solubilizer, emollient, and carrier in advanced formulations. This compound is essential for manufacturers in the personal care, cosmetics, and specialty chemical industries seeking performance-enhancing additives.

Application

• Cosmetic & Personal Care Formulations: Acts as a non-greasy emollient, skin-conditioning agent, and solvent for active ingredients in creams, lotions, and sunscreens.
• Pharmaceutical Excipient: Serves as a solubilizing agent and penetration enhancer in topical drug delivery systems.
• Polymer & Resin Modifier: Used as a plasticizer or co-monomer to modify the flexibility and processing characteristics of specialty polymers.
• Lubricant & Functional Fluid Additive: Imparts lubricity and stability as an additive in synthetic lubricants and industrial fluids.
• Chemical Synthesis Intermediate: A key building block for the synthesis of more complex esters, surfactants, and specialty chemicals.
• Food-Grade Applications (potential): With appropriate certification, can function as a carrier or solvent for flavors and food additives.

Quality Control

Our 1,3-Butanediol-1-Monooctanoate is manufactured under a strict quality management system. Each batch is analyzed to ensure it meets stringent specifications for identity, purity, and composition. Certificates of Analysis (COA) documenting key parameters such as assay, acid value, and moisture content are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture. Keep away from strong acids and incompatible organic solvents.
