PepOil™ Acetyl Tetrapeptide-5 is an oil-compatible liquid concentrate of Acetyl Tetrapeptide-5 for eye-area formulas, especially under-eye puffiness, visible eye bags, dark-circle support concepts and fine-line care.

Acetyl Tetrapeptide-5 is a short cosmetic peptide commonly associated with anti-edema, anti-glycation and periorbital decongesting concepts. The strongest human-use data available publicly is limited and mostly supplier-originated, but the peptide is widely used in eye contour creams and serums where formulators want a targeted peptide for fluid-retention appearance around the lower eyelid.

This product is supplied as an oil-soluble 5000ppm active concentrate. The oil-compatible format lets formulators place the peptide into anhydrous oil gels, facial oils, balm-serums and oil phases where a conventional water-soluble peptide solution is not suitable.

Product Description: Use this ingredient when an eye product needs a peptide positioned for lower-eyelid puffiness and early aging support but the formula architecture is oil based or low-water. The delivered-active target is the important design point: because this product contains 5000ppm Acetyl Tetrapeptide-5, a 2–10% ingredient level delivers approximately 100–500ppm active peptide in the finished formula. A typical 5% use level delivers approximately 250ppm active peptide.

Usage: Eye creams, under-eye serums, facial oils, oil gels, balm-serums and W/O or emulsion systems designed for puffiness, visible eye-bag and anti-aging positioning.

Mixing method:

- Add during the final oil phase or cool-down stage. Keep product temperature below 40°C after addition.

- For oil gels or balm-serums, pre-blend into the liquid oil portion before adding delicate fragrance or heat-sensitive actives.

- Avoid strong oxidizing/reducing systems, high pH, prolonged heating and repeated freeze-thaw exposure. Run compatibility and stability checks in the final package.

Usage rate: 2–10% of this 5000ppm concentrate (delivers approximately 100–500ppm active Acetyl Tetrapeptide-5). Typical: 5% → approximately 250ppm active.

Product characteristics: Clear to yellow liquid concentrate.

Solubility: Clearly dissolves in polar cosmetic oils and polar esters. For non-polar oils, pre-blend with a small amount of Oil Blender™ (Polyglyceryl-3 Diisostearate) until the concentrate becomes clear, then add to the oil phase. Not intended for direct addition to a purely aqueous phase.

Storage: keep tightly closed, protected from light and heat. Store cool when possible.
