Soap Analysis

What is Soap? What are the Types?

Soap, the most basic cleaning material, is defined as the NA and K salts of long-chain organic fatty acids. Soaps have a cleansing effect due to the hydrophobic properties of the hydrophobic part they contain to envelop oil/dirt particles.

Soap, which is found in homes, schools, public places, is a cleaning product that we need in every moment of our daily life. Soap is generally used as a cleanser, as well as in the production of creams, sprays, lotions, cosmetics and medicines. Due to its frequent use and direct contact with our skin, some testing processes are applied to soap from the production stage until it reaches the consumer.

• Solid Soap (Bar Soap): Soaps produced by traditional methods and usually made from olive oil or animal fats. It is widely used for cleaning hands.
• Liquid Soap: Liquid soaps made with caustic potash (KOH) facilitate hygienic use and offer skin-friendly options.
• Antibacterial Soap: It contains active substances that kill bacteria and germs. It is especially preferred in the health sector and public areas.
• Natural Soap: They are environmentally friendly soaps produced entirely with vegetable oils and essences and do not contain chemical additives.

What are Nanolab's Services in Soap Analysis?

• Total Alkali Content Determination (BS 1715-2.1, ISO 684): To control pH balance and skin compatibility by determining the total amount of alkali in the soap.
• Total Free Alkalinity Determination: Measuring the alkalinity remaining free in the soap formulation is important to reduce the likelihood of the product causing skin irritation.
• Free Fatty Acid Amount: It provides information on quality and shelf life by determining the amount of free fatty acids in the soap.
• Determination of Non-Saponifiable, Saponified and Saponifiable Substances: The effectiveness of the formulation is evaluated by determining the proportion of non-saponifiable substances in the product.
• Determination of Soluble / Soluble Substance Amount in Ethanol (Alcohol): Tests the purity of the content by examining the solubility of the substances in the composition of the soap in alcohol.
• Determination of Resin Acids: The presence of resin acids in soap is used as a quality indicator, especially in the analysis of products with natural ingredients.
• Determination of Chloride (TS 54 ISO 457, TS 5155): Measuring the amount of chloride in soap allows inorganic components to be controlled.
• Determination of Inorganic Salts (TS 9676): Determines the inorganic salt content in the soap and optimizes the hardness and usage performance of the product.
• Free Caustic Alkali Determination (NaOH/KOH): Measures the amount of caustic alkali released in the soap to check for residues that may cause skin irritation.
• Determination of the Amount of Water Insoluble Matter (TS 54): It is made to determine the amount of foreign or fillers insoluble in water in soap. High insoluble matter content may reduce the quality of the soap.
• Moisture and Volatile Matter Determination (ISO 672): Determines the amount of water and other volatile compounds in soap. It is important because it has an impact on the shelf life, hardness and performance of the soap.

In our TURKAK accredited laboratories serving in many parts of Turkey, "Soap Analysis" procedures are carried out on the basis of international standards, test methods and relevant legal regulations.
