Basic Properties
rhode peptide liptint is a synthetic peptide blend, typically comprising palmitoyl tripeptide-1, palmitoyl tetrapeptide-7, and additional moisturizing factors. It appears as a fine, off-white to light beige powder with a characteristic peptide odor. The molecular weight ranges between 800–1500 Da, ensuring optimal skin penetration and bioavailability.
Purity & Solubility
Standard bulk lots offer a minimum purity of 98% as verified by HPLC analysis. The compound is freely soluble in water and ethanol, with a solubility of ≥50 mg/mL at 25°C. This high solubility facilitates seamless incorporation into water-based lip tint formulations without the need for complex emulsification steps.
Storage & Stability
For long-term stability, store rhode peptide liptint in a cool, dry environment at 2–8°C, protected from light and moisture. Under these conditions, the product maintains ≥95% potency for 24 months. Avoid repeated freeze-thaw cycles to prevent peptide degradation.
- Purity: ≥98% (HPLC, single peak)
- Appearance: Off-white to light beige powder
- Solubility: ≥50 mg/mL in water, freely soluble in ethanol
- pH Range: 5.0–7.0 (1% aqueous solution)

Industry data from a 2023 cosmetic raw material survey indicates that 87% of peptide-based lip products require a minimum purity of 98% to achieve consistent clinical outcomes, with rhode peptide liptint meeting this benchmark across all tested batches.
Manufacturing & Quality Control
Rigorous manufacturing protocols and quality control measures ensure that every batch of rhode peptide liptint meets the highest industry standards.
Production Process
The synthesis employs solid-phase peptide synthesis (SPPS) using Fmoc chemistry, followed by cleavage, precipitation, and lyophilization. Each step is monitored via in-process HPLC to track purity and yield. Post-synthesis, the product undergoes reversed-phase preparative HPLC to achieve the target purity of ≥98%.
Purification & Third-Party Testing
After purification, the peptide is subjected to comprehensive quality control, including mass spectrometry (MS) for molecular weight confirmation, amino acid analysis for sequence fidelity, and residual solvent testing per USP <467>. Independent third-party laboratories verify all certificates of analysis (CoA) before release.

Frequently Asked Questions
Q1: What is the recommended concentration of rhode peptide liptint in lip tint formulations?
The typical usage level is 0.5–2.0% w/w, depending on the desired intensity of peptide benefits. For standard hydration and texture improvement, 1.0% is a common starting point. Higher concentrations may be used in premium or serum-type products.
Q2: How should I verify the purity of rhode peptide liptint upon receipt?
Request a certificate of analysis (CoA) from the supplier that includes an HPLC chromatogram showing a single peak at the expected retention time. You can also perform in-house HPLC analysis using a C18 column and a water/acetonitrile gradient with 0.1% TFA to confirm purity.
Q3: Can rhode peptide liptint be used in anhydrous lip products?
Yes, but it requires pre-dispersion in a compatible solvent such as ethanol or propylene glycol before incorporation into anhydrous bases. The peptide is not directly soluble in oils, so proper dispersion is critical for uniform distribution.
