Erythrulose is a natural keto sugar commonly found in plants such as raspberry. It is produced by fermenting Gluconobacter, a type of aerobic bacterium. This substance is typically used as a skincare tanning ingredient.
When applied, the substance will react with keratin protein’s amino acids found in the skin epidermis. The skin gradually changes its color due to the non-toxic reaction. This gives the skin a sun tan appearance.
Compared to DHA, the erythrulose effect gradually takes 3 to 10 days. It is also more chemically stable and less skin drying. However, you can use erythrulose with any DHA formulation.

Erythrulose gives natural and gradual tanning of skin. It cross-links amino acids present on the surface of the skin to give a tan effect. This is a controlled process that does not lead to patchiness and gives an even and uniform tone.
Skin stays moisturized as erythrulose doesn’t rob the skin of its valuable moisture. Its gentleness makes it ideal for sensitive cosmetic ingredients in all product lines. This uniformity makes your brand capable of performing consistently in all product lines.

There are many reasons why many top brands in the cosmetics industry use erythrulose in their formulations. Some of the main benefits of erythrulose are:
Erythrulose creates firm bonds with skin proteins. This prolongs the perceivable tan duration by a significant amount. It ensures formulas last a few days with their effectiveness.
The ingredient moisturizes rather than depleting moisture. It is simple to blend with humectants. This preserves formulation smoothness and comfort and improves the tanning efficiency.
Unlike DHA alone, erythrulose does not lead to orange coloration. It mixes to form a natural brown color. This enables products to offer a natural glow without offensive colors.
Erythrulose is dermatologically tested and nontoxic. This makes it ideal for cosmetic products.
This ingredient has a gentle effect on oily, dry, or sensitive skin. It does not irritate or provoke allergies. This makes formulas effective on all skin types.
As a CGMP compliant erythrulose manufacturer and supplier in China, we follow struct production process to ensure you get the highest quality ingredients. Baisifu starts by:
We procure pure erythritol and other fermentation materials from proven suppliers. All raw materials are strictly screened for identity and purity before use. This ensures compliance right from the early stages of manufacturing.
Our manufacturing process employs controlled microbial fermentation technology. The manufacturing process efficiently and reproducibly converts erythritol into high-purity erythrulose. This reduces waste and ensures continuous yields.
Following fermentation, the material is subjected to fine filtration and purification. It is dried with care under controlled conditions in order to stabilize. This gives rise to a free-flowing, homogeneous powder ready for formulation.

Erythrulose cross-links amino acids in skin via the maillard reaction. This results in the production of melanoidin pigments that darken the skin naturally. That natural darkening ensures your products provide a consistent sun-free tanning effect.
The process is less aggressive and slower than using DHA alone. The slowing down of the rate prevents streaks and patchiness. Your products thus provide smoother, more even results that last longer.
Erythrulose synergizes with DHA when combined together. It stiffens and gives longer tan life. Its synergy is very high, which makes your formulation work better with increasingly improved results.
Erythrulose is effective in concentrations of 1–5%. Light effects are obtained with lower concentrations. Greater concentrations achieve more color depth with excellent formulation stability.
It leaves a lasting tan effect that is observed for 3–7 days. With DHA, it prolongs duration even further. This blend enables your formulations to yield consistent and long-lasting results every time.
If you want to achieve better results in your cosmetic product formulations, you should maintain the PH at about 4 to 5. Our test results have proved beyond reasonable doubt that erythrulose efficacy is between PH 4 and 5
Erythrulose has good solubility in water-based formulations. It is easily compatible with extracts and humectants. That compatibility significantly cuts down your formulation process and ensures it is consistent.

Erythrulose must be kept at 2–8°C in a dry and cool place. Keep it tightly sealed in containers to avoid moisture and contamination. Sealing saves your product from getting contaminated and weak.
Keep it away from direct sunlight and humidity. Direct sunlight and too much humidity will contaminate its quality and performance. By doing so, you safeguard your investment and ensure uniform results.
It lasts for two years if stored under good conditions. Storage under the proper conditions guarantees stability and efficacy. In this way, your formulations are dependable and provide consistent performance each time.
Our erythrulose complies with international standards of safety in cosmetics. It is tested rigorously for quality prior to packaging. That means you get uniform COA and MSDS reports with every batch.
Clinical dermatological testing confirms erythrulose to be safe for skin use. It is free from adverse reactions at recommended concentrations. Your products stay up to regulatory standards worldwide.
We also maintain batch-to-batch consistency. Scientific testing guarantees purity, solubility, and stability. This makes your products consistent across all markets.

At the moment, there are many cosmetic ingredients suppliers in China. However, to get a erythrulose supplier who can support your business, it is important to consider:
Select a supplier with good, reliable production capacity. We deliver bulk lots on time for each order. You can run continuously without fear of shortages.
Identify suppliers that adhere to stringent purity levels. Our erythrulose is more than 99% pure and batch to batch consistent. This keeps your formulas stable and gives you reproducible results.
Look for suppliers with set certifications such as ISO, GMP, and ECOCERT. We possess these qualifications to ensure compliance with global cosmetic standards.
Prices play a role in bulk buying. We have quality erythrulose at reasonable prices. This allows your business in the long term to benefit.
At Baisifu, we are here to support your cosmetic brand irrespective whether you are a small or large business. With our flexible MOQs, competitive prices, assistance on cosmetic products formulations and high-grade ingredients, we strive to give you competitive edge in the industry.
The application of Erythrulose is to provide natural and gradual tanning effects in self-tanning formulations.
Yes. It is dermatologically safe and widely accepted.
Of course, it fits in oily, dry and sensitive skin type.
Some of the ingredients that it pairs well with include DHA, humectants, and botanical extracts.
