A1: The recommended usage level varies by product type:

• Moisturizers and creams: 1-10%
• Serums and lotions: 2-8%
• Shampoos and conditioners: 0.5-5%
• Perfumes and fragrances: 1-15%
• Makeup products: 1-5%
  The exact concentration depends on the specific formulation and desired moisturizing effect.

A2: Yes, 1,3-butylene glycol is considered safe for use in cosmetics at the recommended usage levels. It has been approved by regulatory authorities worldwide including the FDA and EU Cosmetics Regulation. It is non-irritating and non-sensitizing to most skin types.

A3: Standard grade 1,3-butanediol is produced from petroleum-based raw materials, while COSMOS approved bio-based grade is derived from renewable plant-based resources. Both grades have the same chemical properties and performance, but the bio-based version meets the requirements for organic and natural cosmetic certifications.

A4: Yes, 1,3-butylene glycol is highly compatible with other humectants such as glycerin, hyaluronic acid and propylene glycol. Combining different humectants can provide synergistic moisturizing effects and improve overall formulation performance.

A5: 1,3-butylene glycol has similar moisturizing properties to propylene glycol but is generally considered gentler on the skin and less likely to cause irritation. It also has a less greasy feel and better odor profile, making it a preferred choice for many high-end cosmetic formulations.

A6: 1,3-butylene glycol has a shelf life of 24 months when stored in tightly sealed original containers at temperatures between 5-30℃. It should be stored in a cool, dry and well-ventilated area away from direct sunlight, heat sources and incompatible materials.
