The cosmetic industry is currently undergoing a significant transformation, with an escalating demand for natural, safe, and functional ingredients. In this evolving landscape, cosmetic-grade diatomaceous earth powder (diatomite powder) has emerged as a highly sought-after additive in a wide array of skin care products. Its unique properties, such as gentle exfoliation and remarkable oil absorption capacity, have positioned it as a key ingredient in facial cleansers, masks, body scrubs, and other skincare formulations. It is crucial to emphasize that this product is strictly intended for external use only, adhering meticulously to industry regulations that prohibit its use in health supplements or internal applications.
Applications in Facial Cleansers
In the realm of facial cleansers, particularly those formulated for oil control, diatomaceous earth powder plays a pivotal role. Its efficacy lies in its ability to effectively absorb excess sebum and thoroughly cleanse pores. The diatomite powder's porous structure endows it with an impressive oil absorption rate of ≥150%, enabling it to absorb two to three times its own weight in oil. When incorporated at a concentration of 5 - 8% (500 - 1000 mesh) in facial cleansers, it can penetrate deep into the pores, eliminating accumulated oil and dirt, thereby reducing the occurrence of blackheads and acne.
A notable case study involves a leading South Korean cosmetics brand that integrated our diatomaceous earth powder into their newly launched oil-control facial cleanser. A clinical trial was conducted on 200 volunteers with oily skin over a period of four weeks. The results were remarkable: 88% of the participants reported a significant reduction in oil secretion, and the number of blackheads decreased by an average of 40 - 60%. The gentle particle size of the diatomaceous earth powder, with a median diameter (D50) of 10 - 20 μm, ensures that it does not cause any abrasions or scratches on the skin. Rigorous skin irritation tests further validated its safety, showing no signs of redness or itching, making it an ideal choice even for individuals with sensitive skin.
Moreover, the unique composition of diatomaceous earth powder interacts harmoniously with other cleansing agents in the formulation. It helps to create a rich, creamy lather that effectively lifts away impurities without stripping the skin of its natural moisture barrier. This balanced cleansing action is essential for maintaining healthy, radiant skin.
Role in Facial Masks
Facial masks, especially those designed for oil control and deep cleansing, greatly benefit from the addition of diatomaceous earth powder. Masks formulated with 10 - 15% diatomaceous earth powder can rapidly absorb excess sebum from both the skin's surface and within the pores. In just 15 - 20 minutes, these masks leave the skin feeling refreshed, clean, and free from the heavy, greasy sensation often associated with oily skin.
A well - known French mask brand utilized our diatomaceous earth powder in their deep - cleaning mask formulation. Advanced skin detection technology was employed to assess the mask's performance. The results demonstrated that the mask was capable of removing an astonishing 90% of the dirt and debris lodged in the pores. Additionally, the unique porous structure of the diatomaceous earth powder not only aids in absorption but also contributes to moisture retention. Post - application, the skin's moisture content increased by 15%, leaving it hydrated and supple.
In contrast to synthetic absorbents like silica gel, diatomaceous earth powder offers a sustainable and eco - friendly alternative. As a natural, biodegradable material, it aligns perfectly with the growing consumer preference for environmentally conscious products. This not only enhances the product's appeal but also reflects positively on the brand's commitment to sustainability.
Function in Body Scrubs
For body scrubs, diatomaceous earth powder serves as an excellent gentle exfoliant. The primary function of body scrubs is to remove dead skin cells without compromising the integrity of the skin barrier. By incorporating 12 - 20% diatomaceous earth powder (300 - 500 mesh) into body scrub formulations, this delicate balance can be achieved.
The irregular particle shape of diatomite powder allows it to gently buff the skin's surface, effectively sloughing off dead skin cells. Its relatively low hardness, with a Mohs hardness rating of 1 - 2, is significantly lower than that of synthetic exfoliants such as polyethylene beads. This ensures that the scrub can exfoliate effectively without causing micro - tears or scratches on the skin.
An American body care brand conducted an in - depth study on the efficacy of their diatomaceous earth powder - based scrub. Volunteers used the scrub once a week for a period of one month. The results were compelling: the skin roughness of the participants decreased by 30%, and their skin became noticeably smoother and more refined. Additionally, the scrub enhanced the absorption of subsequent body lotions by 25%, allowing for better penetration of moisturizing ingredients and maximizing their benefits.
Stringent Quality Control
Our cosmetic - grade diatomaceous earth powder is subject to rigorous quality control measures at every stage of production. The manufacturing process commences with the selection of high - purity diatomite ore, which serves as the raw material. This ore undergoes a series of purification steps, including gravity separation, flotation, and acid leaching, to eliminate any impurities and ensure the highest quality of the final product.
To guarantee the microbiological safety of the powder, it undergoes high - temperature calcination at 1000 - 1200°C. This process effectively sterilizes the powder, resulting in a total bacterial count ≤100 CFU/g and a mold/yeast count ≤10 CFU/g. These low microbial levels are essential for maintaining the integrity and safety of cosmetic products formulated with our diatomaceous earth powder.
Product Specifications
We offer a diverse range of particle size specifications tailored to different cosmetic applications. The fine - grade powder (800 - 1200 mesh) is ideally suited for use in facial cleansers and masks, where a more refined texture is desired. The medium - grade powder (300 - 500 mesh) is perfect for body scrubs, providing just the right amount of exfoliation. For products targeted at sensitive skin, we offer an ultra - fine grade (1200 - 2000 mesh), which is extremely gentle on the skin.
In addition to particle size, the whiteness of our diatomaceous earth powder is ≥90%. This high level of whiteness ensures that it does not impart any unwanted color to the cosmetics, allowing formulators to create products with consistent and appealing aesthetics.
To further enhance its performance in various cosmetic formulations, we also provide surface - modified diatomaceous earth powder. For instance, silane - modified diatomaceous earth powder offers improved compatibility with cosmetic oils and surfactants. This modification prevents agglomeration, ensuring a homogeneous dispersion within the formulation and optimizing the product's overall performance.
In the end our commitment to customer satisfaction extends beyond the quality of our product. We offer free samples ranging from 100g to 500g, allowing our customers to test the powder in their own formulations and assess its performance. Our experienced technical team is always on hand to provide personalized recommendations regarding the optimal addition ratio based on the specific requirements of different product types. As previously mentioned, we recommend 5 - 8% addition for facial cleansers, 10 - 15% for masks, and 12 - 20% for body scrubs.
