Formulation Guidelines for Seaweed Extract, Peptide, Glycerin, and Cucumber Extract

Creating a formulation with seaweed extract, peptides, glycerin, and cucumber extract involves combining water-soluble ingredients. The exact percentages can vary depending on the desired product type (e.g., serum, lotion, cream) and the specific grade or type of each ingredient used.

Here are general guidelines for the typical usage rates of these ingredients in cosmetic formulations:

• Seaweed Extract: Typically used at 1-10%. Products like Sea Kelp Extract are often used at 1-3% for skin/hair care, though up to 10% is possible. Wakame Extract (Brown Sea Weed) is recommended at 1-3%. Note that some extracts like Wakame are sensitive to heat above 40°C, while Sea Kelp can withstand up to 60°C.
• Peptide: The usage rate depends heavily on the specific peptide. For example, Pep®-IDP2 (Decapeptide-4) is typically used at 1-5%, Pep®-Neo (Acetyl Tetrapeptide-2) at 2-10%, and Pep-Even™ (Tetrapeptide-30) at 0.5-5.0%. Always check the recommended usage rate for the specific peptide you choose. Peptides are generally heat-sensitive and should be added in the cool-down phase.
• Glycerin: A common humectant, Glycerin (USP/Food Grade) is typically used at 1-10% in formulations, although it can be used at higher concentrations. It is water-soluble and can usually be added to the water phase.
• Cucumber Extract: Cucumber Extract (France) is typically used at 3-5%. It should be mixed in water and kept below 50°C.

General Formulation Tips:

• These ingredients are primarily water-soluble. You would typically incorporate them into the water phase of your formulation or add them during the cool-down phase if they are heat-sensitive.
• You will need a base for your formulation (e.g., a serum base, lotion base, or ingredients to create an emulsion) and likely a preservative to ensure stability and safety.
• Always refer to the specific supplier's recommended usage rate and mixing instructions for each ingredient you purchase.

This combination of ingredients can create a product focused on hydration, soothing, and anti-aging benefits.
