Alantoína en polvo

Productos

Allantoin (CAS Number: 97-59-6) is a highly pure, cosmetic-grade active ingredient widely recognized by formulators for its exceptional skin-conditioning and soothing properties. Formulated as a fine, free-flowing white powder, our Allantoin 99% is engineered to integrate seamlessly into a broad spectrum of personal care formulations without interfering with the product’s intended color profile or clarity.

In cosmetic chemistry, allantoin functions primarily as a mild keratolytic agent. Rather than physically exfoliating, it works by increasing the water content of the extracellular matrix and enhancing the desquamation of upper layers of dead skin cells. This mechanism helps to soften the stratum corneum while promoting a healthy, smooth skin appearance. It is highly valued in the development of formulations designed for sensitive skin, post-sun care, daily moisturizers, and barrier support applications. Whether you are developing lightweight lotions, rich emulsion creams, or advanced oral care products, this high-purity powder provides consistent, reliable performance batch after batch.

Unique Advantages of Our Allantoin Powder:

• Uncompromising Purity (≥ 99%): Ensures optimal formulation stability, predictable performance, and safety in both leave-on and rinse-off products.
• Formulator-Friendly Appearance: The exceptionally fine white powder format eliminates the risk of color alteration in transparent or lightly colored cosmetic systems, reducing the need for aggressive homogenization.
• Directo de fábrica: Sourced and distributed directly from the original manufacturer, guaranteeing full traceability, strict quality control, and highly competitive pricing structures.
• Scalable Bulk Supply: As a dedicated bulk exporter and global supplier, we provide flexible, customizable packaging tailored for wholesale procurement, ensuring your production lines never experience downtime.

Formulation Guidelines & Applications

Formulating with Allantoin requires a precise understanding of its unique solubility profile. While it is an incredibly effective skin-soothing agent, its integration into aqueous systems must be managed carefully by the formulation team to avoid crystallization and a gritty sensory feel in the final consumer product.

Recommended Usage Rates

Allantoin is highly effective even at low concentrations, making it a cost-effective active for large-scale manufacturing. We recommend the following dosage guidelines based on the final product type:

• Facial Creams & Lotions (Leave-on): 0.1% to 0.5%
• Toners & Aqueous Serums: 0.1% to 0.5% (Do not exceed maximum water solubility at room temperature)
• Shampoos & Body Washes (Rinse-off): 0.5% to 2.0%
• Lip Care & Ointments (Anhydrous Suspensions): Up to 2.0% (Dispersed as a fine powder)

How to Dissolve Allantoin Without Crystallization

The most common challenge formulators face in the lab is the recrystallization of allantoin as the water phase cools down. At standard room temperature (approximately 25°C / 77°F), allantoin’s solubility in water is strictly limited to about 0.5%.

Best Practices for Aqueous Integration:

1. Temperature Control: Add the allantoin powder to the water phase and heat the system to approximately 50°C (122°F). Stir continuously using a standard overhead mixer until the white powder is completely dissolved and the liquid phase becomes entirely clear.
2. Concentration Limits: If your formulation requires a clear, stable liquid at room temperature without the risk of crystallization (e.g., in clear toners or essences), do not exceed a 0.5% concentration.
3. For Higher Concentrations (Emulsions): If a concentration higher than 0.5% is strictly required for efficacy in a heavy cream or ointment, allantoin can be successfully incorporated as a finely dispersed powder during the cool-down phase (below 40°C). Our fine particle size ensures it creates a stable emulsion or suspension without imparting a rough, sandy texture to the final formulation.

Compatibilidad y estabilidad

Our Allantoin Powder 99% exhibits excellent stability across a wide range of cosmetic formulation environments, making it a highly versatile addition to your laboratory inventory.

• pH Tolerance: In our evaluations, allantoin remains highly stable within a pH range of 3.0 to 8.0. It is well-suited for mildly acidic formulations—such as those containing Alpha Hydroxy Acids (AHAs) or Beta Hydroxy Acids (BHAs)—as well as neutral emulsions. Prolonged exposure to highly alkaline environments (pH > 8.0) should be actively avoided, as it may lead to the degradation of the allantoin molecule into urea and other byproducts.
• Ingredient Compatibility: It demonstrates outstanding compatibility with a vast array of common cosmetic ingredients. Allantoin pairs exceptionally well with other barrier-supporting and conditioning agents like Panthenol (Pro-Vitamin B5), Niacinamide, Glycerin, Ceramides, and various high-molecular-weight thickeners (like Xanthan Gum or Carbomers) without inducing phase separation, color shifts, or viscosity loss.
• Storage Stability: When stored properly in its original, tightly sealed packaging in a cool, dry environment away from direct light and moisture, the fine white powder maintains its ≥ 99% purity specification and flowability over an extended shelf life.

Safety & Regulatory Profile

Compliance and safety are non-negotiable elements in B2B raw material sourcing. Our product aligns with the most stringent global standards for personal care ingredients, ensuring smooth regulatory approvals for your finished goods.

• Denominación INCI: Allantoin
• Situación reglamentaria: Universally approved for use in cosmetics and personal care products worldwide, fully compliant with EU Cosmetics Regulation, FDA guidelines, and major Asian cosmetic regulatory frameworks.
• Safety Profile: Allantoin is highly regarded for its excellent dermatological compatibility. According to Cosmetic Ingredient Review (CIR) expert panel assessments, it is recognized as safe for use in cosmetics. It is non-irritating, non-toxic, and non-comedogenic, making it the premier ingredient of choice for sensitive, reactive, or compromised skin profile formulations.

Preguntas más frecuentes (FAQ)

Q: Why does my allantoin powder crystallize after the formulation cools down?

A: This crystallization occurs when the allantoin concentration exceeds its natural room-temperature solubility limit in water (approx. 0.5%). To prevent this issue in your batches, ensure your aqueous concentration stays at or below 0.5%, and dissolve it thoroughly at 50°C during the heated water phase before emulsification.

Q: Can allantoin be used in anhydrous (water-free) formulations?

A: Yes. In anhydrous systems like lip balms, body butters, or heavy ointments, our fine white allantoin powder will not dissolve, but it can be evenly dispersed as a micro-particulate. Due to its fine mesh size, it provides skin-conditioning benefits without making the final product feel overly gritty.

Q: Do you supply this allantoin powder directly from the factory?

A: Yes, we are the original manufacturer and bulk exporter. By sourcing directly from our factory, you bypass trading middlemen, ensuring you receive direct manufacturer pricing, consistent batch-to-batch quality, and fully traceable documentation for every order.

Q: What is your standard packaging for wholesale bulk orders?

A: As a global supplier experienced in large-scale procurement, our standard packaging for commercial production is robust 25kg fiber drums with dual inner poly-bags. This is designed to protect the powder from moisture and contamination during international transit. We can also accommodate custom packaging requests based on your specific procurement volumes.

Q: What is the typical lead time for a bulk commercial order?

A: For standard 25kg drum orders, we maintain steady factory inventory to ensure rapid dispatch. Typical lead times for global shipping depend on the destination, but our supply chain team works closely with your procurement department to ensure strict adherence to your delivery schedules.
