Yinherb Lab High Quality Oligopeptide P11-4 powder CAS. 593266-60-5 99% Purity Min

Generic Name: Oligopeptide P11-4 powder

INCI name: Oligopeptide 104

CAS Number: 1415456-99-3

Molecular Formula: C₇₂H₉₉N₂₀O₂₂

Molecular Weight: 1595.67 Da (exact calculated value)

Chemical Classification: Synthetic sugar derivative (xylose-based tetrahydropyran ring derivative)

Amino Squence: Ac - Gln - Gln - Arg - Phe - Glu - Trp - Glu - Phe - Glu - Gln - Gln - NH₂ (abbreviated as Ac - QQRFEWEFEQQ - NH₂)

Appearance: It is a white to off-white solid powder.

Solubility: It has a solubility of 16.67 mg/mL in DMSO, and ultrasonic treatment can assist in dissolving it. The quality of products on the market is relatively stable, with a common purity specification of 98.02%.

Stability: Excellent stability within the pH range of 3.0–8.0 (compatible with most skincare formulations), heat-resistant (no decomposition under short-term heating at ≤80℃), non-oxidizable, and well-compatible with other active skincare ingredients (e.g., vitamin C, hyaluronic acid).

Purity Requirement: Common specifications include 98% and 99%, and some high-end products can even reach 99.67% purity. The total impurity content is generally ≤2.0%, and the largest single impurity is ≤1.0%, which meets the strict requirements of pharmaceutical research.

What is Oligopeptide P11-4 powder?

Oligopeptide P11-4 Powder (CAS 593266-60-5, ≥98% HPLC) is a synthetic pH-sensitive self-assembling peptide composed of 11 amino acids. Developed for biomimetic enamel regeneration, it selectively forms a 3D hydrogel matrix in acidic oral environments, acting as a scaffold for hydroxyapatite nucleation and growth. It effectively repairs demineralized enamel, reduces dental sensitivity, and prevents plaque formation. Ideal for high-end oral care products and professional dental treatments, it offers a safe, non-invasive alternative to fluoride and abrasive agents.

Core Features

pH-responsive self-assembling peptide with enamel-targeted biomineralization activity;

forms protective 3D matrix only at acidic pH (caries/plaque sites);

high affinity to tooth mineral, guiding natural-like hydroxyapatite growth;

non-invasive, no fluoride or abrasives;

biocompatible, low immunogenicity;

stable in formulation, compatible with common oral care ingredients.

Oligopeptide P11-4 powder Mechanism of Action and Additional Efficacy

Mechanism	Description
pH-Responsive Self-Assembly	Low pH triggers folding into β-sheet 3D hydrogel matrix
Hydroxyapatite Nucleation	Matrix provides Ca²⁺ binding sites, mimicking tooth mineral lattice
Enamel Remineralization	Guides new hydroxyapatite crystal growth, repairing demineralized enamel
Plaque & Sensitivity Control	Blocks bacterial adhesion; occludes dentinal tubules, reducing sensitivity
Biomimetic Mineralization	Matches natural enamel regeneration pathway, no harsh abrasives

Oligopeptide P11-4 powder Application

Enamel regeneration and early caries treatment: It is one of its core applications. For early caries lesions that have not yet damaged the deep tooth tissue, the powder can be used as an active ingredient to prepare relevant preparations. These preparations can promote the remineralization of decayed tooth surfaces and reverse early tooth demineralization. Meanwhile, it can help regenerate damaged enamel, improving the hardness and integrity of teeth.

Relief of dentin hypersensitivity: Dentin hypersensitivity is often caused by the exposure of dentin tubules. The hydrogel-like structure formed by the self-assembly of this peptide powder can block the exposed dentin tubules. This reduces the stimulation of external substances on the dental nerve, thereby alleviating the sensitive symptoms such as soreness caused by cold, heat, acid, and sweetness.

Oral acid protection and care products: It can be added to oral care products such as toothpaste, mouthwash, and dental gels as an active ingredient. It can form a protective film on the tooth surface, enhance the tooth's resistance to acid erosion, and prevent enamel demineralization caused by acidic substances in food or beverages.
