NanoActive DMC

Advanced Delivery System by PuriPharm Co. Ltd.

Liposomal Dimethylmethoxy Chromanol. The ultimate dual-scavenger shield against Reactive Oxygen Species (ROS) and Reactive Nitrogen Species (RNS), engineered for maximum bioavailability.

1. Redefining Antioxidant Protection

Dimethylmethoxy Chromanol is widely recognized as one of the most potent synthetic analogs of γ-tocopherol. Unlike traditional antioxidants that only target Oxygen free radicals, DMC is a unique dual-scavenger, effectively neutralizing both ROS and RNS, preventing lipid peroxidation and protein damage.

However, incorporating DMC into cosmetic formulations presents challenges due to its solubility and stability issues. PuriPharm’s NanoActive technology solves this by encapsulating DMC within nanometric liposomal vesicles. This structural mimicry of the stratum corneum ensures superior stability, profound epidermal penetration, and sustained release of the active molecule.

Key Advantages:

  • Dual Scavenging: Neutralizes both ROS and RNS, offering 360° cellular protection.
  • Liposomal Delivery: Nano-scale vesicles ensure deep penetration and prolonged efficacy.
  • Photo-aging Defense: Prevents UV-induced DNA damage and premature skin aging.
  • Formulation Friendly: Water-soluble liposomes easily integrate into aqueous phases.

2. The Science Behind the Shield

A targeted approach to cellular defense and delivery.

① ROS & RNS Quenching

Environmental stressors (pollution, UV) trigger ROS (like Superoxide) and RNS (like Peroxynitrite). DMC acts as an electron donor, rapidly stabilizing these radicals before they can initiate cascading lipid peroxidation in cell membranes.

② Phospholipid Bilayer Integration

PuriPharm encapsulates DMC in a flexible, biocompatible phospholipid bilayer. This liposome protects the fragile DMC molecule from premature oxidation within the cosmetic formula, dramatically increasing shelf-life.

③ Targeted Release

Due to their nanometric size (< 100nm) and biomimetic nature, the liposomes fuse with the stratum corneum, releasing DMC directly into the deeper epidermal layers where cellular protection is most critical.

3. Technical Specifications

Designed for cosmetic formulators seeking uncompromising quality, stability, and ease of use in advanced skincare architectures.

4. Applications

  • Anti-Aging Serums: Prevent structural protein degradation.
  • Anti-Pollution Creams: Shield against urban environmental stress.
  • Suncare & After-Sun: Mitigate UV-induced oxidative cascade.
  • Brightening Essences: Prevent oxidation-triggered melanogenesis.

NanoActive Sulfur

Introduction

Sulfur is a yellow nonmetal widely distributed throughout the earth and has long been used as an effective treatment for various skin disorders. Its activity depends on the interaction between sulfur particles and keratinocytes: the smaller the particles, the larger the contact area and the better the efficacy. Bio-derived sulfur formed by the bacterial oxidation of sulfides into elemental sulfur shows better spreadability on the skin and higher activity.

NanoActive Sulfur, developed through a nano-delivery system, effectively regulates sebum secretion and helps treat acne and dandruff, while also providing strong antibacterial and anti-inflammatory activity.

Sebum Regulation

Excessive sebum secretion accumulates in follicles, enlarges pores, causes follicular blockage, and may even trigger inflammation.

NanoActive Sulfur effectively removes excess surface oil and helps soften the epidermis. It can also dissolve keratin and relieve skin imbalance caused by overactive oil secretion. In addition, it helps improve acne, pimples, and seborrheic dermatitis associated with overactive sebaceous glands.

Keratolytic Effect

Cystine is a major component of the stratum corneum. At low concentrations, sulfur promotes normal keratinization through its keratoplastic activity. At high concentrations, the same reaction produces a keratolytic effect because hydrogen sulfide disrupts keratin, and sufficient accumulation can dissolve the stratum corneum.

Therefore, NanoActive Sulfur is recommended for cosmetic formulations designed to regulate sebum secretion.

Antibacterial Action

The antibacterial action of sulfur depends on its conversion into pentathionic acid (H₂S₅O₆), a compound toxic to fungi. Hydrogen sulfide may also contribute to this activity. Through the action of skin bacteria and keratin-forming cells, sulfur can be converted into pentathionic acid. In addition, sulfur’s keratolytic activity may help separate fungi from the stratum corneum.

Therefore, NanoActive Sulfur is recommended for cosmetic formulations with purifying and preservative functions.

Pentathionic Acid Activity

Anti-inflammatory Action

Glutathione (GSH) is the most important cellular antioxidant. It exists in the reduced thiol form (GSH) and the oxidized disulfide form (GSSG), and undergoes thiol-disulfide exchange catalyzed by thiol transferases. Severe oxidative stress depletes intracellular GSH.

NanoActive Sulfur can promote GSH synthesis while reducing pro-inflammatory cytokines such as IL-1, IL-6, and TNF-α, delivering a strong anti-inflammatory effect.

Inflammatory Factor Reduction

Inflammatory Factor Reduction

The protein expression levels of TNF-α, IL-1β, and IL-6 were measured by ELISA.

Compared with the control group, NanoActive Sulfur reduced the expression of TNF-α, IL-1β, and IL-6 in a dose-dependent manner.

Challenges in Sulfur Applications

Advantages of NanoActive Sulfur

NanoActive Sulfur has a unique chemical structure (linear and hydrophilic), making it easier to formulate, easier to combine with other ingredients, and easier to absorb.

Nano-delivery System

NanoActive Sulfur developed with a nano-delivery system (NDS) has a particle size below 30 nm. It completely solves sulfur solubility issues by stably encapsulating sulfur inside nano-carriers, greatly improving absorption efficiency and bioavailability.

Puri-Xyl THE 3D HYDRATION EXPERT

The Challenge: Dehydrated Skin

Signs of Imbalance

Environmental stress and aging disrupt the skin’s natural water balance, leading to:

  • Visual Dryness:Flaking and dullness.
  • Physical Discomfort:Tightness and roughness.
  • Structural Weakness:Compromised barrier function.

The Goal: To restore equilibrium between water reserves and water loss.

Introducing Puri-Xyl

Natural Sugar Technology:

Puri-Xylis auniquecomplex of natural sugars derived fromWheat andCorn. It represents a green chemistry approach to skin hydration.

INCI Name: Xylitylglucoside,Anhydroxylitol, Xylitol

Key Attributes: Preservative-free,Allergen-free, Non-GMO.

Green Synthesis & Structure

TheHydraconcept: 3D Hydration

Mechanism 1: Dermal Reserves

Mechanism 2: Barrier Function

Ceramide Synthesis: A healthy barrier relies on the “mortar” holding cells together. Puri-Xylsignificantly stimulates the synthesis ofCeramides 1 & 2.

The Result: This creates an “Anti-Dehydration Shield,” physically preventing water from evaporating and protecting against external aggressors.

Mechanism 3: Water Circulation

Aquaporins (AQP3): Puri-Xylupregulates Aquaporin-3, the dedicated water channels in cell membranes. This ensures active transport of water and glycerol from the dermis to the epidermis.

Tight Junctions: By reinforcing tight junctions, Puri-Xylensures that water flow is controlled and distributed evenly throughout the epidermal layers, maximizing hydration efficacy.
