a type of polypropylene glycol that’s widely used in cosmetics for its multifunctional properties

PPG-9 is a type of polypropylene glycol that’s widely used in cosmetics for its multifunctional properties. Here’s an overview of its role in cosmetic formulations:

What Is PPG-9?

• Chemical Nature: PPG-9 is a polypropylene glycol where the “9” refers to the average number of propylene oxide units in the polymer chain. This lower molecular weight version is especially prized for its balance of water and oil solubility.
• Versatility: Its chemical structure allows it to interact well with both aqueous and lipid phases, making it an adaptable ingredient in various formulations.

Key Functions in Cosmetics

• Humectant:
  PPG-9 helps attract and retain moisture in the skin. By drawing water from the environment, it helps keep skin hydrated, which is essential for maintaining skin barrier function.

• Solvent:
  It acts as a solvent for many active ingredients and additives, ensuring that ingredients mix uniformly in formulations like lotions, creams, and gels.

• Skin Conditioning:
  PPG-9 can improve the texture of cosmetic products, contributing to a smooth, non-greasy feel on the skin. This enhances the overall sensory experience for the user.

• Emollient:
  Its emollient properties aid in softening and smoothing the skin, making it a common component in moisturizers and creams.

Applications in Cosmetic Products

• Moisturizers and Creams:
  Used to boost hydration and improve product texture, leading to a more pleasant application and better skin feel.

• Hair Care Products:
  Incorporated in shampoos and conditioners, it helps to create formulations that are less drying and more manageable.

• Cleansers and Makeup Removers:
  Its solvent properties help dissolve oils and other substances, enhancing cleansing efficacy.

• Sunscreens and Other Topicals:
  Improves the spreadability of formulations, ensuring even application of active ingredients.

Usage: Mix in serum, lotion or cream.

Mixing method: Can be mixed in several steps.

Usage rate: 1-20% (do not use more than 50%)

Product characteristics: Clear liquid, similar to oil.

Solubility: Soluble in water.

Storage: Can be stored at room temperature, but close the bottle tightly and keep away from sunlight or heat. The product has a shelf life of at least 2 years.
