Red cell ketone: No sun exposure, no tanning—and a beauty-boosting formula

In the ever-evolving landscape of beauty chemistry, consumers are increasingly seeking safer, more natural alternatives to achieve sun-kissed skin without UV exposure. One such compound that has gained attention in recent years is the red blood cell ketone DHB supplement, known by CAS numbers 533-50-6 and 40031-31-0. Derived naturally, this ketone offers a unique mechanism for skin pigmentation, making it an essential ingredient in modern self-tanning products.

While DHA (dihydroxyacetone) remains the most well-known active ingredient in sunless tanning products, DHB red cell ketone supplements complement DHA by enhancing color depth, longevity, and overall aesthetic appeal. Unlike traditional tanning methods or synthetic chemicals, DHB works through a gentle, non-toxic reaction with proteins on the skin’s surface—reminiscent of the Maillard reaction—resulting in a natural-looking tan that’s even, streak-free, and free from any orange undertones.

What is red blood cell ketone? Learn about its chemical identity.

Red blood cell ketone DHB supplement, also known as rubycellin, is a four-carbon ketose sugar that occurs naturally in certain fruits, such as raspberries and cranberries. It is typically produced via fermentation using non-pathogenic bacteria, ensuring a safe, high-purity product suitable for cosmetic applications.

For CAS numbers 533-50-6 or CAS: 40031-31-0, erythritone is a water-soluble, non-reducing sugar that reacts slowly with free amino acids in the outermost layer of the skin—particularly those found in epidermal keratin.

Unlike other tanning agents, erythrulose doesn’t penetrate deeply into the skin, nor does it cause irritation or photochemical reactions. Instead, it triggers a controlled browning reaction—similar to the Maillard reaction—that gradually imparts a golden hue to the skin’s surface.

How do red blood cell ketones work in self-tanning products?

The mechanism behind red blood cell ketone-induced skin discoloration involves the slow interaction between its carbonyl groups and primary amines present in skin proteins. This reaction generates melanoidins—brown-colored polymers that mimic the appearance of natural melanin, all without involving any UV radiation or hormonal stimulation.

Compared to DHA, which reacts relatively quickly and reaches its peak within 2–4 hours, erythritone develops more gradually, often taking up to 24–48 hours to deliver its full effect. This slower reaction results in a more natural, streak-free tan—especially when combined with DHA.

Due to its mild nature and low reactivity, red cell ketone is highly suitable for:

Sensitive skin formula

Gradually self-tanning

Facial Tanning Cream

Colored moisturizers and BB creams

Our company provides high-purity erythrocyte ketone (CAS No. 533-50-6) for cosmetic manufacturing, ensuring consistency and safety across various skin types and formulations.

Why are red cell ketones combined with DHA in the self-powder product?

Although DHA is the only active ingredient used for sunless tanning, it can sometimes lead to unwanted results—such as uneven application, an orange tint, or rapid fading. By incorporating erythrulose into the formula, manufacturers can minimize these issues while enhancing both the depth and longevity of the tan.

Here's how combining DHA with erythrulose can enhance sunless tanning results:

More natural color development: Red cell ketones impart a warmer, redder tone, counteracting the grayish or pale yellow hues that sometimes accompany DHA.

Extended wear time: The dual-power mechanism slows down color fading, significantly prolonging the lifespan of the brownish hue.

Improved consistency: The slower development of red cell ketones ensures a smoother, more even application.

As a result, many advanced self-tanners now feature optimized ratios of both DHA and erythrulose, delivering users a more refined, salon-quality finish.

The Application of Red Blood Cell Ketones Beyond the Skin

Although best known for its role in cosmetic tanning products, chrysoeriol is also showing promise in other niche areas:

Hair coloring and keratin treatments

Its ability to react with keratin makes chalcone a promising candidate for temporary hair colorants, particularly in formulations designed for gray coverage or subtle color effects. When applied topically, it interacts with the amino groups in hair proteins, creating soft, natural-looking shade variations—without the need for harsh dyes or ammonia.

Skincare and Anti-Aging Formulas

Preliminary research suggests that erythroketone, thanks to its moisturizing properties and ability to stabilize skin proteins, may offer both hydration and antioxidant benefits. These characteristics make it an appealing ingredient for anti-aging creams, serums, and barrier-repair formulations.
