1,2-Butylene Glycol is a multifunctional cosmetic ingredient used in skincare, haircare, personal-care and cosmetic formulations. It is also known as 1,2-Butanediol, Butane-1,2-diol and 1,2-Dihydroxybutane.
1,2-Butylene Glycol has the molecular formula C₄H₁₀O₂, a molecular weight of approximately 90.12 g/mol, and CAS Number 584-03-2. It is generally supplied as a clear, colorless to light-yellow liquid.
In cosmetic formulations, 1,2-Butylene Glycol can provide multiple functions, including humectancy, solvent activity, skin conditioning and viscosity control. These properties make it useful in formulations where moisture support, ingredient solubilisation and formulation texture are important.
1,2-Butylene Glycol is a four-carbon aliphatic diol containing two hydroxyl groups positioned at the 1 and 2 positions of the carbon chain.
Its systematic chemical name is Butane-1,2-diol. The term 1,2-Butylene Glycol identifies the positions of the hydroxyl groups and distinguishes this ingredient from other butanediol isomers.
It is important to distinguish 1,2-Butylene Glycol from 1,3-Butylene Glycol. Although both have the same molecular formula and molecular weight, they have different molecular structures and different CAS numbers:
Accurate chemical identification is therefore important for procurement, formulation, technical documentation and SEO product-page accuracy.

1,2-Butylene Glycol can function as a humectant in cosmetic formulations. It can contribute to moisture retention and is therefore suitable for hydration-focused skincare and personal-care products.
1,2-Butylene Glycol can function as a solvent or co-solvent for compatible cosmetic ingredients. This property can assist formulators in incorporating selected ingredients into aqueous and mixed-phase formulations.
1,2-Butylene Glycol can contribute to the conditioning characteristics and sensory profile of finished cosmetic products. It can be used in formulations designed for comfortable skin application.
1,2-Butylene Glycol can contribute to controlling the flow and viscosity characteristics of cosmetic formulations. Its use can help formulators achieve the desired texture and application profile.
The multifunctional nature of 1,2-Butylene Glycol makes it useful as a supporting ingredient in different cosmetic formulation systems, including aqueous products, gels and emulsions.
1,2-Butylene Glycol can be considered for:
Its humectant and solvent properties make it suitable for formulations where hydration and ingredient incorporation are important.
Potential applications include:
1,2-Butylene Glycol can be used in selected facial cleansers, body washes and other personal-care cleansing formulations.
Potential applications include:
It can also be considered for various personal-care formulations where a multifunctional glycol with humectant, solvent and viscosity-support properties is required.
1,2-Butylene Glycol is generally handled as a liquid cosmetic ingredient. Reference data describes it as a clear, colorless to light-yellow liquid, with water compatibility suitable for formulation use.
The appropriate concentration should be determined according to the intended product function, formulation type, ingredient compatibility and applicable cosmetic requirements.
Formulators should evaluate compatibility with surfactants, emulsifiers, fragrances, botanical ingredients, cosmetic actives and other solvents present in the finished formulation.
Special attention should be given to chemical identity during procurement because 1,2-Butylene Glycol and 1,3-Butylene Glycol are different compounds.
Storage and handling should follow the applicable product specification, SDS and supplier documentation.
