| Catalog Number | CI-HC-0208 |
| Product Name | Butylene Glycol (CAS 107-88-0) |
| CAS | 107-88-0 |
| Structure |  |
| Description | Butylene Glycol is a chemical compound with the molecular formula C4H10O2. It is a colorless, odorless, and viscous liquid that is commonly used as a solvent, humectant, and skin conditioning agent in various cosmetic and personal care products. Butylene Glycol helps to enhance the effectiveness of other ingredients in a product, while also helping to keep the product from drying out. It also has hydrating properties that help to keep skin moisturized and soft. In addition, Butylene Glycol is used as a preservative and a viscosity regulator in many products, including lotions, creams, and hair care products. |
| Appearance | clear, odorless, and slightly viscous liquid |
| Application | 1. As a skin-conditioning agent: Butylene glycol is commonly used in skincare and cosmetic products as a humectant, which helps to retain moisture and improve skin texture. 2. As a solvent: Butylene glycol is a versatile solvent that can be used to dissolve a wide range of compounds in both water-based and oil-based formulations. 3. As a viscosity modifier: Butylene glycol can be used to adjust the viscosity of formulations, making them thicker or thinner as required. 4. As a preservative: Butylene glycol has antimicrobial properties and can help to extend the shelf life of products by preventing the growth of bacteria and other microorganisms. 5. As a surfactant: Butylene glycol can be used as a surfactant to help emulsify and disperse oils and other hydrophobic substances in water-based formulas. 6. As a flavor or fragrance enhancer: Butylene glycol is commonly used in food and beverage applications as a flavor enhancer, and in personal care products as a fragrance enhancer. |

The surface morphology of cosmetic films composed of amphiphilic random copolymers (methoxy polyethylene glycol-23 methacrylate/glyceryl diisostearate methacrylate copolymer, MPM-GDM) and solvents was studied. The surface morphology was adjusted by changing the solvent composition of 1,3-butylene glycol (1,3-BG) (a good solvent for MPM-GDM) and glycerol (a poor solvent for MPM-GDM), thereby improving the functionality and feel of the cosmetic films.
Preparation procedure of mixtures for films
· For two or three-component mixtures, MPM-GDM and various solvents (water, methanol, ethanol, 2-propanol, 1-butanol, ethylene glycol, 1,3-BG, 1,4-BG, and glycerin) were mixed in a glass test tube using a vortex mixer or spatula for mixing viscous samples. The mixtures were then left to stand at 40°C for 2-7 days before cooling to room temperature.
· In the case of four or five-component mixtures, xanthan gum was mixed with solvents (1,3-BG and glycerin) in a glass test tube at room temperature. MPM-GDM was later added to the mixture, which was then heated above 40°C and stirred manually. Water was added, and the mixture was stirred with a magnetic stirrer for several hours before cooling to room temperature. The weight ratio of MPM-GDM to xanthan gum was either 1:0.05 or 1:0.01, with the total amount of solvents (excluding water) kept constant while varying the weight fraction.

In order to address the safety issues of paraben preservatives in cosmetics, this work evaluated the preservative effect of 1,3-butanediol, 1,2-hexanediol and 1,2-pentanediol as alternative paraben preservative systems.
Evaluation methods and results
· The effectiveness of 1,3-butylene glycol as a preservative in cosmetic creams was assessed by conducting a M-3 challenge test with concentrations ranging from 5% to 25%. Similar evaluations were also conducted on alkane diols such as 1,2-hexanediol and 1,2-pentanediol. The results of the study showed that 1,3-butylene glycol exhibited effective preservative properties against a variety of microbial strains (including S. aureus, E. coli, P. aeruginosa, C. albicans, and A. niger) at a concentration of 25%.
· Additionally, combinations of 0.3% phenoxyethanol and 0.1% ethylhexylglycerin were tested, as well as the efficacy of alkane diols like 1,2-hexanediol and 1,2-pentanediol as potential alternatives to phenoxyethanol. The results indicated that both 1,2-hexanediol and 1,2-pentanediol at a concentration of 1% exhibited preservative efficacy.
In conclusion, the combination of 25% 1,3-butylene glycol and 0.1% ethylhexylglycerin, as well as 1% 1,2-hexanediol and 1% 1,2-pentanediol, demonstrated the most effective preservative efficacy among all the compositions tested in the study.
