Butylene glycol: the unsung hero of cosmetics
In the world of cosmetics, butylene glycol (1,3-BG) is an unassuming but highly effective ingredient found in a wide variety of skincare and beauty products. This article highlights the many benefits of butylene glycol, particularly in its role as a multifunctional ingredient in the cosmetics industry.
Introduction
Butylene glycol, chemically known as 1,3-butanediol, is a colorless, odorless liquid valued in both water- and oil-based formulations for its excellent solution properties and ability to penetrate the skin barrier. Its versatility makes it a prized ingredient in cosmetic and personal care products.
What is butylene glycol?
Butylene glycol belongs to the family of glycols that are commonly used in the cosmetics industry to moisturize, improve texture, and act as a solvent for other ingredients. It is particularly known for its ability to effectively transport active ingredients into the skin and improve their absorption.
Benefits of butylene glycol in cosmetic products
- Moisturizing properties
One of the most outstanding properties of butylene glycol is its ability to bind and retain moisture in the skin. Studies have shown that butylene glycol retains moisture in the skin better and longer than other glycols, making it an ideal ingredient for moisturizing products.
- Improving texture
Butylene glycol gives many skin care products a silky, non-greasy texture. It helps products spread evenly over the skin without leaving a sticky feeling, which is especially appreciated in face creams and lotions.
- Solvent for active ingredients
As a solvent, it plays a crucial role in dissolving active ingredients and distributing them evenly throughout a product. It is particularly effective at dissolving plant extracts and vitamins used in skin care formulations, making it one of the most commonly used solvents.
- Antimicrobial properties
Butylene glycol not only improves skin moisture and texture, but also has antimicrobial properties. It helps to increase the effectiveness of preservatives in aqueous formulations by improving their solubility and distributing the antimicrobial effect throughout the product.
- Enhanced skin penetration
Another important benefit is its ability to increase the penetration of other active ingredients through the skin. This is particularly important for products designed to reach deeper layers of the skin for maximum effectiveness.
Environmentally friendly and safe
In addition to being effective, butylene glycol is also safe and environmentally friendly. It is completely biodegradable and well tolerated by skin, making it an excellent choice for formulations where safety and environmental awareness are top priorities.
Conclusion
Butylene glycol is an invaluable ingredient in the world of cosmetics. Its ability to moisturize, improve penetration into the skin and act as a solvent for other key ingredients makes it an essential component of many skincare products. Its safety and environmental compatibility enhance its importance in sustainable product lines.
Butylene glycol is an example of how innovative science and careful formulation can work together to create products that are both effective and safe for consumers and the environment.
That is why we also use butylene glycol in product development for our customers, because it is now also available in 100% green, sustainable types. Please ask us for more information or development of outstanding serum textures.
