Sodium hydroxymethylglycinate, with the CAS number 70161-44-3, is a high - quality chemical compound. It is a white to off - white powder, easily soluble in water. The molecular formula of Sodium hydroxymethylglycinate is C₃H₆NNaO₃. It has a relatively stable chemical property under normal storage conditions. The melting point of this compound needs to be determined under specific laboratory conditions, and it is sensitive to high temperatures and strong acids.
In terms of quality control, our product of Sodium hydroxymethylglycinate meets high - end industry standards. The purity of our product is usually above 99%, which ensures its high - quality performance in various applications. It is also produced under strict quality management systems to guarantee its safety and reliability.
Sodium hydroxymethylglycinate has a wide range of uses. In the cosmetics industry, it is widely used as a preservative. It can effectively inhibit the growth of bacteria, fungi, and yeasts in cosmetic products, extending their shelf - life. For example, in skin - care products such as lotions, creams, and shampoos, it helps to keep the product fresh and free from microbial contamination, ensuring the safety of consumers using these products.
In the personal care industry, it is also used in toothpaste, mouthwashes, and deodorants. In toothpaste, it can prevent the growth of harmful bacteria in the oral cavity while maintaining the stability of the toothpaste formula. In deodorants, it helps to control the odor - causing bacteria, keeping people feeling fresh throughout the day.
Additionally, Sodium hydroxymethylglycinate can be used in the industrial field. It can be applied in water - based paints and coatings as a preservative to prevent microbial spoilage during storage and use, thus improving the quality and durability of these products.
When using Sodium hydroxymethylglycinate in cosmetics, it is recommended to add it at the final stage of the production process, when the temperature of the product is below 50°C. The recommended dosage is usually between 0.1% - 0.5%, depending on the specific formulation and the expected preservative effect. Before large - scale use, it is necessary to conduct a small - scale test to ensure compatibility with other ingredients in the formula.
In personal care products like toothpaste and mouthwashes, it should be added according to the specific formulation requirements. Usually, a lower dosage is sufficient, around 0.05% - 0.2%. It should be evenly mixed with other ingredients to ensure its uniform distribution in the product.
For industrial applications such as in water - based paints and coatings, it can be added during the mixing process. The dosage is generally 0.2% - 1%, depending on the environmental conditions and the expected shelf - life of the product.
Case 1: A well - known cosmetic brand used Sodium hydroxymethylglycinate in its new line of facial creams. Before using this preservative, the brand faced issues with microbial contamination in some batches of products, which led to product recalls and a negative impact on brand image. After adding Sodium hydroxymethylglycinate at a dosage of 0.3%, the microbial growth in the products was effectively controlled. The shelf - life of the creams was extended from 12 months to 18 months, and there were no more reports of microbial - related quality problems. This not only saved costs for the company but also improved the brand's reputation in the market.
Case 2: An industrial paint manufacturer added Sodium hydroxymethylglycinate to its water - based paints. Previously, the paints would often develop a bad smell and show signs of spoilage during long - term storage. By adding 0.5% of Sodium hydroxymethylglycinate, the paint remained stable during a one - year storage test. The paint's performance, such as its adhesion and gloss, was not affected, and it maintained its quality even in high - humidity environments.
