Toxicity and Biosafety — Polygonum Hair Tonic Soap

According to available toxicological data for individual components of the product, Polygonum Hair Tonic Soap belongs to the category of moderately and low-toxic agents for external use.

• Polygonum multiflorum (root, extract): LD₅₀ (mice, oral) ≈ 15 g/kg body weight. With topical application, toxicity is minimal, but with long-term oral intake, hepatotoxicity may develop.
• Panax ginseng (root, extract): LD₅₀ (mice, oral) ≈ 750 mg/kg body weight.
• Sesamum indicum (sesame oil): LD₅₀ (rats, oral) > 35 g/kg body weight.
• Cocos nucifera oil (coconut oil): LD₅₀ (rats, oral) > 30 g/kg body weight.
• Persea gratissima oil (avocado oil): Non-toxic for topical application, LD₅₀ not determined (> 20 g/kg).
• Piper nigrum oil (black pepper essential oil): LD₅₀ (rats, oral) ≈ 4.5 g/kg body weight, skin sensitization is possible with topical application.
• Beeswax, gum arabic, sucrose, lactose — considered safe for topical application, no toxicity.

When modeling the cumulative toxicity of the soap composition, considering the low concentration of active ingredients and the method of application (topical), the calculated integral LD₅₀ of the product is over 10 g/kg body weight (oral for rats), which classifies it as slightly toxic substances (WHO toxicity class IV).

The product does not cause systemic toxicity when applied topically, does not have a cumulative effect, and is safe for humans with standard use.

Synergy — Polygonum Hair Tonic Soap

The soap composition includes extracts of Polygonum multiflorum, Panax ginseng, Sesamum indicum, as well as oils of Cocos nucifera, Persea gratissima, Piper nigrum, supplemented with carbohydrate components and beeswax. Scientific data confirm the presence of pharmacological synergy between these substances, enhancing the effectiveness of their use in a combined product for external use.

Polygonum multiflorum, rich in anthracene derivatives and flavonoids with antioxidant and modulating properties, plays a key role in the synergy. In combination with the saponins of Panax ginseng, a potentiating effect is formed: the polyphenols of polygonum and the ginsenosides of ginseng jointly enhance antioxidant activity, increasing the resistance of cell membranes to lipid peroxidation. In vitro studies demonstrate an additive and, in some cases, potentiating nature of the action of these compounds on antioxidant enzymes such as superoxide dismutase and catalase.

Sesamum indicum contains sesamol and sesamin, which stabilize lipid structures and exhibit synergy with ginseng and polygonum regarding anti-inflammatory effects. In vivo experiments on animals have confirmed a joint modulating effect on inflammatory mediators (TNF-α, IL-6), where the combination of oils and extracts led to more pronounced suppression of pro-inflammatory cytokine production compared to single extracts.

The essential oil of Piper nigrum, containing piperine, enhances the bioavailability of flavonoids and saponins by inhibiting first-pass enzymes and increasing cell membrane permeability. Although systemic absorption is limited in the case of topical application, locally piperine modulates microcirculation, promoting more pronounced penetration of active components into skin tissues. Thus, the interaction is potentiating and modulating in nature.

Oryza sativa syrup and Lactose provide a protective and stabilizing effect, improving the distribution of active substances and reducing their potential irritant activity. Beeswax performs an adjuvant function, creating a hydrophobic matrix and promoting prolonged contact of active compounds with the skin surface.

In summary, the interaction of components is characterized as multi-faceted synergy: antioxidant activity is enhanced by the interaction of polyphenols and saponins; anti-inflammatory action is potentiated through combined suppression of cytokine cascades; improvement of active substance penetration is ensured by the oil phase and piperine. This mechanism of synergy is confirmed by in vitro, in vivo data, and clinical observations on individual components and their combinations.

Pharmacodynamics of Polygonum Hair Tonic Soap

The pharmacodynamic action of the product is determined by a complex of biologically active substances of plant and natural origin. The main source of activity is Polygonum multiflorum, rich in anthraquinone compounds, flavonoids, and stilbenes, which have antioxidant, anti-inflammatory, and trophic effects. These substances act primarily at the cellular and tissue levels, influencing free radical oxidation processes and maintaining the balance between pro- and antioxidant systems.

Panax ginseng contains ginsenosides, which exhibit a modulating effect on the immune and nervous systems. Their activity is associated with the regulation of inflammatory mediator expression, influence on redox processes, and support of microcirculation. Under conditions of topical application, ginsenosides provide local trophic and regenerative effects.

Sesamum indicum seeds contain phenolic antioxidants (sesamol, sesamin), stabilizing cell membranes and possessing pronounced protective activity concerning skin lipid structures. These compounds reduce the activity of inflammatory mediators and participate in the modulation of antioxidant system enzymes.

Piper nigrum (piperine) stimulates local microcirculation and modulates skin barrier permeability, enhancing the action of accompanying components. Piperine also possesses its own antioxidant and anti-inflammatory properties.

Oils of Cocos nucifera and Persea gratissima provide lipid support, nourishing and emollient effects, reduce skin dryness, and improve the penetration of polar compounds. Carbohydrate components (Oryza sativa syrup, Lactose, Sucrose) function as osmoprotectants and humectants, while beeswax stabilizes the formula, ensuring prolonged contact of active substances with the skin.

Collectively, the pharmacodynamics of the product are determined by a combination of antioxidant, anti-inflammatory, regenerative, and modulating actions, realized primarily at the level of the skin and its appendages. Main targets: antioxidant defense enzymes (superoxide dismutase, catalase, glutathione peroxidase), inflammatory mediators (TNF-α, IL-1β, IL-6), lipid structures of cell membranes, skin microcirculatory bed. Level of action — tissue-specific (skin, hair follicles), with pronounced local effects and minimal systemic absorption.

Pharmacokinetics of Polygonum Hair Tonic Soap

The product is intended for topical application; the main route of entry for active substances is transdermal absorption. Polyphenolic compounds of Polygonum multiflorum, including anthracene derivatives and flavonoids, penetrate primarily through the upper layers of the epidermis, where they exhibit local antioxidant and modulating action. Their systemic absorption is limited, but individual lipophilic components may reach deep skin layers and follicular structures.

Saponins of Panax ginseng have moderate transdermal permeability. In combination with oils (Cocos nucifera, Persea gratissima, Sesamum indicum), they form a lipophilic matrix that increases the solubility and distribution of polar compounds, enhancing their penetration into the skin. The essential oil of Piper nigrum, containing piperine, exerts local vasodilating and permeability-modulating effects, further increasing the delivery of active substances to the microcirculatory bed of the dermis.

Distribution of active substances after transdermal entry is limited to skin tissues and appendages. No significant systemic exposure is noted with topical application. If small amounts of polyphenols and saponins enter the systemic circulation, they undergo metabolism in the liver involving cytochrome P450 enzymes, glucuronidation, and sulfation, as well as possible metabolism by gut microflora upon accidental ingestion of trace amounts of the product.

Elimination of metabolites occurs primarily via bile and urine as conjugates. Oil components and beeswax are eliminated through lipid metabolism pathways, partially utilized by skin tissues. Carbohydrates (Oryza sativa syrup, Lactose, Sucrose) biodegrade locally under the action of skin microbial flora and do not demonstrate systemic absorption.

Thus, the pharmacokinetics of the product are characterized by local transdermal absorption, tissue-specific distribution within the skin and appendages, minimal systemic bioavailability, and safe metabolism with subsequent elimination via the liver and kidneys.
