Hair Coat Serum Formula Review

This formula is suitable for use as a hair coat serum designed to protect against heat from styling and nourish the hair.

• Usability and Texture: The combination of silicones like Cyclopentasiloxane, Silicone Shine Max15™, and Dimethicone, along with natural oils such as Olive CLEAR (Hydrogenated Olive Oil), Argan Oil, and Jojoba Oil, is well-suited for a hair serum. The high percentage of volatile and low-viscosity silicones will provide a lightweight feel, good slip, and shine. Based on these ingredients, the serum should not be sticky. The Olive CLEAR (Hydrogenated Olive Oil) is also described as light and non-greasy, further contributing to a pleasant texture.

• Mixing Method: This is an anhydrous formula (contains no water). You can mix the ingredients together using hand mixing until they are uniformly combined. A mixer is not necessary but can be used if preferred. Heat is not required as all ingredients are liquid oils or silicones at room temperature.

• Shelf Life: The formula includes Mild Preserve Eco at 1%, which is within the recommended usage rate for general cosmetics. This preservative, combined with the stability of the silicones and hydrogenated oils, suggests a good shelf life. With proper storage (tightly sealed, away from direct sunlight and heat), you can expect the serum to last for approximately 2 years. However, for commercial production, it is always recommended to perform a microbial challenge test to confirm the exact shelf life for your specific formulation and production conditions.

This serum should effectively provide shine, conditioning, heat protection, and nourishment to the hair.
