Hair Dye Testing Labs in Chennai - TNTH

The Bureau of Indian Standards (BIS) has set specific standards for testing hair dyes. The relevant standards for oxidation hair dyes in liquid, gel, and cream forms are covered under IS 8481:20051. This standard specifically covers hair dyes based on para-phenylenediamine (PPD)/ aryl amine.

  • The BIS has also prescribed standards for other types of hair dyes.
  • IS 10350:2019: Specification for powder hair dyes
  • IS 15205:2005: Specification for oxidation hair dyes (emulsion type)

It’s important to note that the manufacturer is at liberty to describe their ‘Hair Dye’ product as ‘Hair Colour’ or ‘Hair Colorant’, since ‘Hair Dye’, ‘Hair Colour’, and ‘Hair Colourant’ are synonyms

What is Animal Feed testing ?

Animal feed testing labs in Chennai analyze samples of animal feed to assess their nutritional composition, quality, and safety. Here's an overview of the process involved in animal feed testing: Sample Collection: The first step is to collect representative samples of the animal feed to be tested. Samples should be collected following proper sampling procedures to ensure accuracy and reliability. Preparation of Samples: Once collected, the samples may need to be prepared or homogenized to ensure uniformity and consistency. This may involve grinding, mixing, or sub-sampling the feed samples as needed. Selection of Testing Parameters: Depending on the specific requirements and objectives of the testing, various parameters may be analyzed, including: Nutritional Composition: This includes testing for moisture content, protein content, fat content, fiber content, carbohydrate content, and mineral content. Contaminants : Testing may be conducted to detect contaminants such as afla...

What are the symptoms of vitamin A deficiency?

Vitamin A deficiency can lead to a range of symptoms, and its severity can vary. Vitamin A is crucial for various bodily functions, including vision, immune system function, and skin health. Here are some common symptoms of vitamin A deficiency: Night Blindness: One of the earliest and most characteristic signs of vitamin A deficiency is difficulty seeing in low-light conditions or night blindness. This occurs because vitamin A is essential for the synthesis of rhodopsin, a pigment in the eyes that helps with low-light vision. Dry Eyes and Xerophthalmia: Insufficient vitamin A can lead to dryness of the conjunctiva and cornea, causing a condition known as xerophthalmia. In severe cases, it can lead to corneal ulcers and blindness. Skin Changes: Vitamin A plays a role in maintaining healthy skin, and its deficiency can result in various skin issues. Dry, rough skin, as well as the development of follicular hyperkeratosis (thickening of hair follicles), may occur. Impaired Immune Functio...

The Attenuated Total Reflectance (ATR) technique is used in FT-IR spectroscopy

Attenuated Total Reflectance (ATR) is a powerful measurement technique used in FT-IR spectroscopy. Let’s explore its applications and how it works: 1. Identification of Chemical Compounds:  ATR-FTIR spectroscopy helps identify chemical compounds by analyzing their unique infrared absorption patterns.  It’s particularly useful for characterizing organic and inorganic materials. 2. Studying Molecular Structures:  ATR provides insights into molecular structures, including functional groups and bonding arrangements. Researchers use it to investigate polymers, proteins, and other complex molecules. 3. Surface Properties Examination:  ATR allows surface analysis without extensive sample preparation.  It’s valuable for studying thin films, coatings, and interfaces. 4. Analyzing Polymers:  Polymer characterization benefits from ATR due to its ability to analyze solid samples directly. Researchers study polymer composition, additives, and degradation. 5. Biomolecule...
