Dimethyloctynediol

Updated: 2026-09-11

Overview

Dimethyloctynediol is a synthetic organic compound primarily used in the cosmetics and personal care industry. It functions as a surfactant and viscosity regulator, enhancing the texture and stability of formulations. Its mild antimicrobial properties also make it a useful additive in products requiring preservation. The compound is often found in shampoos, conditioners, and skincare products due to its ability to improve product performance without causing significant irritation. Its versatility and safety profile have made it a popular choice among formulators.

Physical and Chemical Properties

Dimethyloctynediol appears as a white crystalline powder with a molecular weight of 142.20 g/mol. It is soluble in both water and organic solvents like ethanol, making it easy to incorporate into various formulations. The compound has a melting point of approximately 90-92°C, which is typical for similar diol compounds. Its surfactant properties stem from its molecular structure, which allows it to reduce surface tension between liquids. This property is particularly valuable in emulsifying and stabilizing cosmetic products. Additionally, its mild antimicrobial activity helps extend the shelf life of formulations.

Main Applications

The primary use of dimethyloctynediol is in the cosmetics and personal care industry. It is commonly added to shampoos, conditioners, and lotions to improve viscosity and texture. Its surfactant properties help create stable emulsions, ensuring even distribution of ingredients. Beyond cosmetics, dimethyloctynediol is also used in industrial applications where mild surfactants or viscosity modifiers are needed. Its safety and effectiveness make it a versatile ingredient in various formulations, though its use outside personal care is less common.

Safety and Storage

Dimethyloctynediol is generally considered safe for use in cosmetics, but it may cause mild skin irritation in sensitive individuals. Proper handling, including the use of gloves and eye protection, is recommended to minimize exposure. Storage should be in a cool, dry place, away from direct sunlight to maintain stability. Regulatory guidelines vary by region, so it's important to ensure compliance with local standards when formulating products containing this compound. Its low toxicity profile makes it suitable for use in products intended for direct skin contact.

B2B Procurement Guide

When procuring dimethyloctynediol, buyers should verify the purity and quality of the product. Reputable suppliers will provide certificates of analysis (CoA) to confirm compliance with industry standards. Pricing can vary based on quantity and supplier, so obtaining multiple quotes is advisable. Bulk purchases may offer cost savings, but storage capacity and shelf life should be considered. Buyers should also check for any regulatory restrictions or documentation requirements in their target markets to avoid delays or compliance issues.
