Butylene glycol is a small organic alcohol commonly used as a humectant in skincare and cosmetic products. It is derived from petroleum and is often used as a substitute for propylene glycol due to its better skin penetration abilities. Butylene glycol has hydrating properties that help to attract and retain moisture in the skin, making it an effective ingredient in moisturizers and serums.

• Hydration: Butylene glycol is a humectant, meaning it attracts and retains moisture in the skin, helping to keep it hydrated.

• Enhanced product penetration: Due to its small molecular size, butylene glycol can penetrate the skin more easily than other ingredients, allowing for enhanced delivery of other beneficial ingredients in skincare products.

• Non-irritating: Butylene glycol is considered to be non-irritating and suitable for all skin types, including sensitive skin.

• Texture enhancer: Butylene glycol can help to improve the texture of skincare products, making them smoother and easier to apply.

• Stabilizer: Butylene glycol is often used as a stabilizer in skincare and cosmetic formulations, helping to maintain the effectiveness of other ingredients in the product.

Overall, butylene glycol is a versatile and effective ingredient commonly used in skincare and cosmetic products to enhance hydration, improve product texture, and facilitate better penetration of other beneficial ingredients.
