Dipalmitoyl Hydroxyproline (DPHP)-CAS 41672-81-5
Dipalmitoyl Hydroxyproline (DPHP) is a premium functional anti-aging cosmetic raw material modified by lipophilic grafting. As an upgraded derivative of hydroxyproline, it combines the moisturizing and collagen-repairing properties of amino acids with the excellent skin-fitting and penetrating advantages of lipophilic groups. It can efficiently penetrate the stratum corneum, stimulate the proliferation and collagen synthesis of dermal fibroblasts, inhibit collagen degradation, and significantly improve skin elasticity and firmness. With stable physical and chemical properties, good formula compatibility and no skin irritation, it is a core raw material for high-end anti-aging and firming skin care formulas, widely recognized and applied in the global cosmetic industry.
Key Benefits
• Excellent Transdermal Penetration: Lipophilic modified structure greatly improves skin absorption capacity, solving the defect of low bioavailability of ordinary hydroxyproline ingredients.
• Efficient Anti-Aging & Firming: Activates dermal fibroblasts, boosts endogenous collagen synthesis, reduces fine lines and sagging, and lifts skin firmness significantly.
• Long-Lasting Moisturizing Effect: Possesses excellent water-locking and moisturizing properties, improves skin hydration, relieves dry and rough skin, and repairs skin barrier.
• Good Formula Compatibility: Stable in oil-water dual formulas, compatible with most cosmetic raw materials such as peptides, hyaluronic acid and plant extracts, no adverse reaction.
• Global Safety Compliance: Complies with international cosmetic safety standards, non-toxic, non-irritating, safe for long-term facial and body skin use.
• Stable Batch Quality: High-purity refined process, low impurity content, stable efficacy in different batches, convenient for industrial mass formula production.
Applications
• Anti-Aging Skin Care Products: Core ingredient for anti-wrinkle essence, anti-aging cream, firming lotion and rejuvenating skin care products, improving skin aging problems fundamentally.
• Firming & Lifting Cosmetics: Applied in facial firming serum, neck cream, body tightening lotion to improve facial sagging and body skin relaxation.
• Moisturizing & Repairing Products: Added in high-end moisturizing cream, barrier repair lotion and sensitive skin care products for long-term moisturizing and skin conditioning.
