Biocidal products are chemical substances that destroy microorganisms, reduce their harmful effects or control them. These products are widely used in many areas such as disinfectants, antiseptics, surface cleaners and the like. However, determining the possible effects of biocidal products on human health is extremely important. Biocidal skin irritation analyses are critical safety tests that evaluate whether the products cause any irritation or harmful effects when applied to the skin. Biocidal skin irritation analyses are a test process that aims to evaluate irritative reactions such as redness, burning and swelling that may occur in the short and long term after the direct application of biocidal products to the skin. These analyses are performed to ensure that the products can be used without harming human health.
Skin irritation test for biocides is an in vitro non-animal test designed to differentiate chemicals and mixtures that may cause moderate skin irritation.
According to the Biocidal Products Regulation (BPR), biocidal products are substances that have a chemical or biological effect on harmful organisms, killing, removing or inhibiting their growth. These products can be used alone or in combination with other products.
Biocidal products play an important role in preventing epidemics and ensuring hygiene. They help maintain the hygiene chain in food businesses. Another benefit of biocidal products is that they protect materials and surfaces from biological damage. They also provide environmentally friendly solutions with correct and conscious use.
Biocidal products are divided into different categories according to their effects and areas of use. Some of these types are as follows:
Disinfectants and General Biocidal Products: They are used to provide hygiene in homes, hospitals and food processing facilities. Hand disinfectants, surface cleaners, antiseptic solutions are some of the products in this category.
Preservatives: Preservatives are used to prevent products from spoiling. Wood preservatives, paint preservatives, cosmetic preservatives are some of them.
Biocidal Products for Pests: These products are used to control insects, rodents and pests. They are produced in the form of insect sprays, rat poisons, mosquito repellents.
Water Treatment Products: They are used to purify pool or drinking water from harmful microorganisms. Pool chlorines, water disinfectants are products in this category.
In Vitro Skin Irritation Test is performed in our laboratory using the OECD Test Guideline 439 in vitro Skin Irritation test method.
Irritation refers to the evaluation of the irritating effect of a product or chemical on the skin. Skin irritation usually manifests itself with symptoms such as redness, swelling or tenderness. Irritation tests are of great importance, especially for evaluating the safety of substances used in cosmetics, cleaning, biocidal products and medical devices.
Symptoms of skin irritation may vary from person to person. In addition, the degree and form of irritation and irritation of biocidal products that have come into contact with the skin may even be related to the person's last meal. Some foods may trigger irritation on the skin more. Some of the symptoms of skin irritation are as follows:
Reactions such as redness, swelling, inflammation or abrasion may be observed on the skin.
Biocidal products classified as cosmetic products, disinfectants, preservatives and pest control products require irritation tests because they are applied to surfaces that people come into contact with or directly to the skin.
Irritation test procedures are generally based on exposing a reconstructed human epidermis (RhE) model to a pure test chemical and then determining cell viability.
In Vitro Skin Irritation analysis is a modern test method that evaluates the risk of irritation using cell-based methods without the use of live animals. This analysis offers an effective solution from both ethical and scientific perspectives. In Vitro Skin Irritation analysis is a laboratory-based process used to determine the skin irritation potential and is especially preferred for irritation testing in biocidal products.
OECD 439 is an international guide for In Vitro Skin Irritation tests. This guideline defines the standards used to evaluate the skin irritation potential of chemical and biocidal products. The OECD 439 guideline includes the necessary protocols to obtain reliable and reproducible results. When performing irritation testing in biocidal products, it is particularly necessary to comply with the OECD 439 methodology.
Irritation testing in biocidal products is of critical importance to protect human health and ensure the safe use of products. These tests are performed to determine whether biocidal products have an irritating effect on the skin. In particular, In Vitro Skin Irritation tests, carried out in accordance with the OECD 439 guideline, are one of the most reliable methods of irritation testing processes for biocidal products.
In Vitro Skin Irritation analyses conducted within the scope of OECD 439 include the following steps:
Preparation of Test Sample: Proper preparation of the biocidal product or chemical to be tested.
Use of Three-Dimensional Skin Model: Testing is performed on three-dimensional skin models with properties similar to human skin.
Cell Viability with MTT Analysis: Irritation potential is determined by measuring the survival rate of cells.
Interpretation of Results: Test results are evaluated according to the criteria of the OECD 439 guideline.
In Vitro Skin Irritation tests reduce ethical concerns as they are an alternative to live animal experiments.
Analyses conducted in accordance with OECD 439 guidelines provide fast and reliable results in a short time.
Irritation testing in biocidal products helps products meet legal requirements before they are put on the market.
Irritation (In Vitro Skin Irritation) analysis is of great importance in irritation testing processes in biocidal products. These tests, conducted in accordance with the OECD 439 directive, both protect human health and ensure that products comply with legal standards. Irritation is a critical parameter in safety assessments and In Vitro Skin Irritation methods are the most effective tools of this process.
