BioSyn-Bisabolol establishes a robust safety standard characterized by a purity level of ≥98% and a single (-)-α levorotatory configuration, which ensures the complete absence of irritating Oxide B impurities commonly found in synthetic alternatives.

Laboratory evaluations using 2D and 3D cell models confirm that a minimal concentration of 3μg/ml yields high inhibition rates for pro-inflammatory markers, specifically 80% for NO, 76% for IL-6, and 77% for TNF-α.

Furthermore, its Natural Index of 1 and REACH registration support its use in high-tolerance formulas by effectively reducing transepidermal water loss (TEWL) and blocking reactive oxygen species (ROS), thereby safeguarding the skin barrier without causing sensitization or irritation.

Non-Irritating

Purity and Configuration

In skin care, whether bisabolol causes irritation primarily depends on its purity and molecular structure.

BioSyn-Bisabolol has significant differences from common chemical synthetic products on the market.

Impurities generated during the chemical synthesis process are often the culprits behind skin discomfort.

BioSyn is produced through bio-fermentation technology, resulting in a molecular configuration identical to the shrub extracts found in nature.

Due to its extremely high purity and absence of oxide residues, it is very friendly to the skin barrier and does not cause additional burden.

Pro-inflammatory Marker Inhibition

To verify its non-irritating and soothing effects, the technical team conducted multiple assessments on 2D and 3D cell models.

At extremely low concentrations (3μg/ml), this ingredient performs excellently in inhibiting inflammatory reactions.

• Nitric Oxide (NO) Inhibition Rate: Reaches 80%. NO is an important marker of      early inflammation; a high inhibition rate means it can quickly control      stinging sensations.

• Interleukin-6 (IL-6) Inhibition Rate: Reaches 76%. Reducing the production of this      substance can effectively alleviate skin redness, swelling, and burning.

• Tumor Necrosis Factor (TNF-α) Inhibition Rate: Reaches 77%. This is crucial for maintaining      the long-term stability of the skin.

These digital indicators demonstrate that it not only generates no irritation itself but also actively inhibits skin inflammation induced by the external environment (such as UV rays and chemicals).

International Standards and Compliance Evaluation

The development of BioSyn-Bisabolol strictly adheres to the rigorous requirements of the international cosmetics industry.

1. REACH Registration: Complies      with the EU Registration, Evaluation, Authorization, and Restriction of      Chemicals regulation, ensuring safety for human health and the environment      throughout its lifecycle.

2. Natural Ingredient Certification: The Natural Index is equal to 1, which means it belongs to      pure natural source ingredients, complying with international standards      such as ISO 16128.

3. Industry Awards: Due to its      sustainability and excellent safety assessment results, the raw material      received award recognition from in-cosmetics Asia in      2023.

Barrier Protection and Free Radical Scavenging

In addition to direct anti-inflammatory data, it also performs well in protecting the skin surface from oxidative stress.

• Neutrophil Inhibition: It can      interfere with the "respiratory burst" process of neutrophils.      Simply put, it blocks the massive release of reactive oxygen species (ROS)      in the body, thereby preventing oxidative damage to healthy cells.

• Reduce Transepidermal Water Loss (TEWL): While improving the penetration efficiency of other      ingredients, it does not damage the skin's natural moisturizing barrier;      instead, it helps maintain skin moisture content and reduces itching      caused by dryness.

Non-Sensitizing Evidence

BioSyn-Bisabolol has a purity higher than 98%, and its composition is a single (-)-α-bisabolol configuration.

Experimental data shows that at a concentration of 0.1%, the inhibition rates of IL-1α and PGE2 in the EpiKutis® 3D epidermal model are 72% and 62%, respectively.

In 2D cell testing, the inhibition rates for inflammatory mediators IL-6 and TNF-α reached 76% and 77%.

The ingredient is completely free of sensitizing impurities Bisabolol Oxide A and B, meeting PCPC and CosIng safety standards, and is suitable for sensitive skin and baby care products.

Chemical Composition and Impurity Control

The safety of BioSyn-Bisabolol is built upon precise control of its molecular structure.

Through biosynthesis technology, this ingredient excludes common by-products found in traditional processes.

Inflammatory Mediator Inhibition

When subjected to external pressure (such as UV rays or chemical irritation), the skin produces inflammatory mediators.

BioSyn-Bisabolol reduces the probability of skin redness or stinging by regulating relevant pathways.

• Cytokine Blocking: In 2D cell      experiments, for LPS-induced inflammatory responses, BioSyn-Bisabolol's      inhibition rate for IL-6 was 76%, for TNF-α was 77%, and for nitric oxide      (NO) reached 80%.

• 3D Model Validation: UVB      damage tests were performed using the EpiKutis® 3D human epidermal model.      At a dose concentration of 0.1%, the expression of IL-1α decreased by 72%      and Interleukin-6 (IL-6) decreased by 59%.

• Prostaglandin Regulation: In      the same test environment, the inhibition rate of PGE2 (the main mediator      causing pain and erythema) reached 62%, proving its performance in      alleviating skin stress reactions.

Action Pathways and Molecular Mechanisms

The non-sensitizing nature of BioSyn-Bisabolol is not just physical non-irritation, but also reflected in its regulation of internal skin signaling pathways.

The ingredient reduces the production of pro-inflammatory substances at the transcriptional level by inhibiting the activation of NF-kB (Nuclear Factor kappa-light-chain-enhancer of activated B cells) and AP-1 (Activator Protein-1).

Simultaneously, it can down-regulate the expression of iNOS (inducible Nitric Oxide Synthase) and COX-2 (Cyclooxygenase-2).
