Niacinamide Bulk Powder

What is Niacinamide?

Niacinamide Bulk Powder, also known as nicotinamide or vitamin B3, is an amide compound of niacin (nicotinic acid) and an important member of the B vitamin family. It is a white crystalline powder, a water-soluble vitamin, and has wide applications in the pharmaceutical and cosmetic fields. As one of the precursors of nicotinamide adenine dinucleotide (NAD+), nicotinamide participates in key physiological processes in the human body, such as cell metabolism, energy production, and DNA repair. It can be used as a dietary supplement to increase NAD+ levels and also as a clinical treatment drug in dermatology. Niacinamide and niacin are collectively known as vitamin PP, and both have similar physiological activities in the human body, promoting cell metabolism and preventing and treating rough skin. However, it is worth noting that nicotinamide does not have the vasodilatory effect of niacin, and therefore does not cause adverse reactions such as facial flushing, making it more advantageous in cosmetics and oral supplements.YTBIO's 98%+ high-purity niacinamide, with its standard purity, stable properties, and excellent water solubility, provides a reliable raw material guarantee for oral nutritional supplements and functional skincare products. YTBIO niacinamide strictly adheres to international quality systems and holds full certifications including cGMP, FSSC22000, BRC, HACCP, HALAL, KOSHER, ISO9001, and ISO22000, ensuring the high safety and efficacy stability of every batch of products.

CERTIFICATE OF ANALYSIS：

The mechanism of action of nicotinamide

Niacinamide powder is well-known for its whitening effect. Unlike the common whitening mechanism that inhibits tyrosinase, nicotinamide mainly inhibits the transfer of melanosomes from melanocytes to keratinocytes. In othr words, it cuts off the transfer path of melanin. Achieve whitening effect. In addition, it can accelerate the metabolism of melanin keratin and enhance its whitening effect; it can also maintain skin moisture, promote microcirculation in the dermis, and strengthen the skin barrier.

Niacinamide for skin care

In 1974, Girish, Parsad, Mathur and others in the UK first discovered that combining nicotinamide and sunscreen into a cream system could absorb ultraviolet rays to prevent tanning and sunburn. Since then, many scientific research institutions have begun to pay attention to its application in the field of cosmetics. At first, nicotinamide was gradually promoted as a whitening ingredient. Later studies found that nicotinamide also has anti-aging, pore shrinking, and acne removal effects.

01 Anti-glycation, improve skin tone

The whitening mechanism of nicotinamide includes three aspects: inhibiting the formation of melanin granules, inhibiting the transmission of melanin to keratinocytes, accelerating the transfer of melanin in keratinocytes to the stratum corneum, and promoting the shedding of the stratum corneum. At the same time, nicotinamide also has the effect of anti-glycation. During the aging process of skin, the contents of NADH (reduced coenzyme I) and NADPH (reduced coenzyme II) gradually decrease, and both control the entire process of intracellular synthesis and decomposition. High levels of NADPH exert a powerful antioxidant effect and prevent the spontaneous glycosylation reaction of proteins and sugars. The glycated proteins produced by the glycosylation reaction will be deposited in the dermis, causing the skin to appear yellowish-brown.

As the precursor of NADH and NADPH, Pure niacinamide powder can play a role by regulating the balance of their levels in the body; nicotinamide can significantly increase the content of NADPH to exert an anti-glycation effect, thereby diluting the yellow color of protein glycation and brightening skin color.

02 Strengthen skin barrier and fight aging

Ceramide is an important component of the skin barrier. Niacinamide enhances the skin barrier function by increasing the ceramide content in the stratum corneum, reducing transepidermal water loss and improving skin resistance. In addition, nicotinamide can also promote the synthesis of proteins in the epidermis, so nicotinamide is also widely used in anti-aging skin care products. Long-term use of skin care products containing nicotinamide can improve skin texture and significantly reduce fine lines and wrinkles.

03 Balance oil secretion and shrink pores

A considerable number of enlarged pores are caused by excessive secretion of oil in the skin. Pure niacinamide powder can significantly inhibit the production of sebum and make the secretion of sebum more appropriate and even. As oil secretion decreases, the pores, the channels through which the skin excretes sebum, will also slowly shrink, achieving the effect of shrinking pores.

04 Anti-inflammatory and anti-acne

Research shows that gel containing 4% nicotinamide is as effective in treating acne as 1% clindamycin gel. At present, the anti-inflammatory mechanism of nicotinamide is not clear. It may achieve anti-inflammatory effects by inhibiting the release of histamine from mast cells, inhibiting leukocyte chemotaxis and secretion of inflammatory mediators, blocking histamine receptors, and inhibiting the transfer of lymphocytes. effect.

Precautions for Niacinamide

01 Skin irritation of nicotinamide

Although niacinamide is very powerful, it is often criticized for its irritation. When using high-concentration nicotinamide products, many people will experience skin intolerance and allergic reactions such as redness, swelling, itching, and stinging. The concentration of nicotinamide is below 2%, and the absorption rate increases with the amount added. It is linear. When the concentration reaches 2%, the absorption rate will not increase linearly. However, as the concentration of nicotinamide added increases, the effect is better, but the irritation will also increase. When choosing niacinamide products, you should start with low concentrations. If your skin can tolerate it, then gradually choose higher concentration niacinamide products. Before using high-concentration niacinamide, first use moisturizing lotion to moisturize the skin and adjust the skin to the best condition to slow down the penetration of niacinamide into the skin and reduce irritation.

02 Niacinamide cannot be mixed with ingredients whose pH value is acid

The cause of niacinamide intolerance is mostly due to niacin. Niacinamide has the best stability in solutions with a pH value of 6. In solutions with a pH value higher or lower than 6, it will be hydrolyzed to form niacin. Niacin will increase the rate of adverse skin reactions, so it contains nicotinamide. Formulated products generally control the pH value between 5 and 7 to reduce the formation of niacin. Therefore, niacinamide products are not suitable to be mixed with other acid products. If mixed, the pH value of the skin will change, and niacinamide will release a large amount of niacin, causing irritation to the skin.

Niacinamide: Multi-Industry Applications and Addition Recommendations

Nutritional Supplements

As a high-quality dietary supplement ingredient, Niacinamide Bulk Powder provides an essential source of vitamin B3 for food and health products. It supports human energy metabolism, maintains skin health, and can be widely used in multivitamin tablets, functional beverages, and fortified foods.
