Vitamin B5 or pantothenic acid is an essential nutrient for humans. It is involved in the synthesis of coenzyme A (CoA), an important molecule in metabolic processes. It is also involved in the synthesis of many important substances, including fatty acids. Pantothenic acid is not synthesized in the human body and must be obtained from the diet. It is found in nearly all foods to some extent, with the highest amounts in whole grains, legumes, eggs, meat, and avocados.
Its name derives from the Greek "Παντοθένη," which means "everywhere," as it is widely distributed in foods.
The industrial synthesis process of pantothenic acid can be divided into several steps:
- Preparation of starting material: The starting compound for synthesis is beta-alanine. This can be obtained from natural sources, such as uric acid, or chemically synthesized.
- Formation of intermediate: Beta-alanine is converted into an intermediate called 4-phosphopantothenate. This reaction requires the addition of phosphate groups to beta-alanine.
- Conversion to pantothenate: The 4-phosphopantothenate intermediate is further transformed into pantothenate through a dephosphorylation process. This reaction involves the removal of phosphate groups from the intermediate.
- Purification: The obtained pantothenate is purified to remove any impurities present in the final product. This can be done using techniques such as filtration, crystallization, or chromatography.
- Formulation and packaging: Once purified, pantothenic acid can be formulated into various products, such as food or pharmaceutical supplements. Subsequently, it is packaged in suitable containers for distribution and sale.
What it is for and where
Medicine
Pantothenic acid helps growth, regenerates the skin and helps supply energy to the body. It performs important functions in the adrenal glands and in the nervous system.
Vitamin B5 is found in lentils, peas, cereals, soy, peanuts while in animals it is found in meat, eggs, liver, milk.
The cases of deficiency of this vitamin are very rare and coincide with strong states of malnutrition.
It is widely used in the healthcare sector and in cosmetic products.
Vitamin B5 has been used, with some success, in the treatment of light acne (1), useful as a prevention of skin infections from pathogenic agents (2) and an adjunct in the treatment of hair loss (3).
Cosmetics
Antistatic agent. Static electricity build-up has a direct influence on products and causes electrostatic adsorption. The antistatic ingredient reduces static build-up and surface resistivity on the surface of the skin and hair.
Hair conditioning agent. A significant number of ingredients with specific and targeted purposes may co-exist in hair shampoo formulations: cleansers, conditioners, thickeners, matting agents, sequestering agents, fragrances, preservatives, special additives. However, the indispensable ingredients are the cleansers and conditioners as they are necessary and sufficient for hair cleansing and manageability. The others act as commercial and non-essential auxiliaries such as: appearance, fragrance, colouring, etc. Hair conditioning agents have the task of increasing shine, manageability and volume, and reducing static electricity, especially after treatments such as colouring, ironing, waving, drying and brushing. They are, in practice, dispersants that may contain cationic surfactants, thickeners, emollients, polymers. The typology of hair conditioning agents includes: intensive conditioners, instant conditioners, thickening conditioners, drying conditioners. They can perform their task generally accompanied by other different ingredients.
Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.
