Myristoyl-Lys-Leu-Ala-Lys-Lys-NH2 · CAS 959610-30-1

The peptide

Myristoyl Pentapeptide-17

Myristoyl Pentapeptide-17 is a synthetic myristoylated pentapeptide. PubChem CID 127264611 records the sequence as myristoyl-Lys-Leu-Ala-Lys-Lys-NH2, five amino-acid residues, molecular formula C41H81N9O6, molecular weight 796.1 g/mol, and CAS 959610-30-1.

Formulate Labs supplies it as a cosmetic raw material for finished topical products, in 35% glycerin/water or Sea Kelp Bioferment, at 0.1% or a 1% lab concentrate. It is not a hair-growth drug. Match the five-residue sequence on the lot certificate of analysis. A six-residue sequence is a different compound.

Why formulators reach for it

A peptide with a long cosmetic-science track record.

Recorded pentapeptide identity

PubChem CID 127264611 lists myristoyl-Lys-Leu-Ala-Lys-Lys-NH2, five amino acids, CAS 959610-30-1, formula C41H81N9O6, 796.1 g/mol.

Supplied as a suspension

Aqueous glycerin/water or Sea Kelp Bioferment, at 0.1% or a 1% lab concentrate.

Cosmetic raw material

For leave-on cosmetic formulas. Do not make hair-growth drug claims. Finished-product claims have to be substantiated by the brand.

Confirm the lot

Match the five-residue sequence and CAS 959610-30-1 on the certificate of analysis. A six-residue sequence is a different peptide.

This product, Myristoyl Pentapeptide-17 (INCI), is a raw material for cosmetic formulation and is not a branded finished cosmetic product or a specific trade-name active.

Published research

Peer-reviewed literature for due diligence.

Myristoyl Pentapeptide-17 is myristoyl-Lys-Leu-Ala-Lys-Lys-NH2, PubChem CID 127264611, CAS 959610-30-1, 796.1 g/mol. It is a cosmetic raw material. Do not treat supplier lash-serum marketing as an independent clinical finding for this suspension. These are independent, third-party papers we link for formulators evaluating mechanism, tolerability, and published panel data. We did not conduct this research and do not guarantee replication in your finished formula.

Formulation guide

Built for chemists who sweat the details.

Typical use rate

1%–10% of the 0.1% (1X) suspension (industry recommended); 0.1%–1% of the 1% (10X) lab concentrate for the same in-formula peptide level of approximately 0.001% – 0.01%

Solubility

Water-soluble peptide, supplied already dissolved in a glycerin / water or Sea Kelp Bioferment aqueous carrier. Add to the water phase.

pH compatibility

Keep the finished formula in the acidic range (approximately 4.0–6.0). This suspension sits in the selected preservative window.

Add at

Cool-down, at or below 40 °C. Protect from direct light; the peptide is light-sensitive.

Mixing

Incorporate into the water phase with gentle mixing. High shear is not required.

Avoid

Strong oxidisers, sulfuric or phosphoric acids, acetic anhydride, sustained heat above 45 °C, prolonged pH above 7.0, and prolonged direct sunlight.

Pairs well with

Lash- and brow-serum vehicles, humectants, complementary cosmetic peptides, and Sea Kelp Bioferment when a marine carrier is desired.

Self-preserving

Yes - 2% Linatural MBS-4. Boost preservation per your finished-formula needs

Documentation

Compliance & safety

The fine print, in plain English.

What it’s for

Cosmetic raw material - leave-on hair-care formulations (scalp serums, hair tonics, leave-on hair lotions, density-positioned conditioning treatments) at the use rates above; also acceptable in rinse-off cosmetic products and skincare formats where a peptide-based "supports the look of fuller hair" / scalp-comfort positioning is intended. Not a finished consumer product; not for ingestion, injection, or unsupervised topical use outside a formulated finished product.

Claims guidance

Cosmetic structure / function language only (e.g. supports the appearance of fuller-looking lashes, supports thicker-looking brows, conditions lashes). Avoid lash-growth drug language (“grows lashes”, “lash growth treatment”, “Latisse alternative”). Do not make therapeutic claims. The peptide is studied in cosmetic in-vitro and panel work; downstream finished-product claims must be substantiated by the brand.

Storage

Store between 2-25 °C in original sealed container away from direct light.
Cold storage extends shelf life by ~50% relative to room temperature.
Once opened, use within the period stated on the COA.

Regulatory

INCI: Myristoyl Pentapeptide-17 (per ICID and PCPC dictionary).
Not classified as hazardous based on currently available information per OSHA HazCom 2012 / GHS.
Compatible with FDA cosmetic regulations and EU 1223/2009 for the intended use.
SDS section 16 disclaimer applies; see the per-recipe SDS for the full classification.

Sensitivity

Myristoyl Pentapeptide-17 is generally well-tolerated in cosmetic use at the rates above; the supplier’s HET-CAM and AMES studies on the peptide indicate non-irritating and non-mutagenic behavior at industry-standard concentrations. The peptide is light-sensitive: store and ship in opaque containers, and avoid prolonged exposure to direct sunlight in finished formulations. Avoid prolonged contact with strong oxidisers, sulfuric or phosphoric acids, acetic anhydride, sustained heat above 45 °C, and prolonged exposure to pH > 7.0 - any of these can hydrolyze the peptide and reduce in-formula activity. Patch-test finished formulations per standard cosmetic protocol.
