Vitamin B5 (Pantothenic acid) is a precursor of the coenzymes involved in more than 100 different metabolic pathways including energy metabolism of carbohydrates, proteins, and lipids, and the synthesis of lipids, neurotransmitters, steroid hormones, porphyrins, and hemoglobin. It is referred to as the “anti-stress” vitamin due to its ability to enhance the activity of the immune system and improve the body’s ability to withstand stressful conditions.
Pantothenic Acid/Yeast Polypeptide is a protein complexed Vitamin B5, an effective ingredient in hair and skin care applications. It is often found in hair care products because of the belief that it makes hair more manageable, softer, and shinier.
Yeast and mushrooms are excellent sources of pantothenic acid. Vitamin B5 is complexed with low molecular weight yeast proteins or polypeptides to form Pantothenic Acid/Yeast Polypeptide, resulting in a water-dispersible complex. It is a cream to light brown powder with a slight characteristic odor.
The solubility and protein complexation are of prime importance for the utilization of the vitamin: absorption is greatly increased, infiltration into the dermal structures is facilitated, and toxicity or irritation potential is almost completely eliminated.
