- Solubility: Euxyl K350 is completely water-soluble, with low irritation, making it suitable for use in cosmetics.
- Application Range: It is suitable for various cosmetics, including leave-on and rinse-off products, such as creams, lotions, facial masks, and wet wipes.
- Biodegradability: Euxyl K350 is biodegradable and stable against hydrolysis, temperature, and pH changes.
- INCI Name: Phenoxyethanol, Methylparaben, Ethylparaben, Propylene Glycol, and Ethylhexylglycerin.
Phenoxyethanol (and) Methylparaben (and) Ethylparaben (and) Propylene Glycol (and) Ethylhexylglycerin. Euxyl K350 preservative acts as a preservative and has a broad, balanced spectrum of effects against bacteria, yeasts and mold. It has good vapor phase effectiveness and is a typically biostatic product with the biocidal properties necessary for practical use. It is fully effective in anionic as well as cationic and non-ionic systems. Euxyl K350 preservative is biodegradable and is stable to hydrolysis, temperature and pH. It can be used in leave-on as well as rinse-off products and wet wipes.
The main components of Euxyl K350 are methyl chloroisothiazolinone (MCI) and methyl isothiazolinone (MIT), which are compounded in a certain proportion. Generally speaking, the ratio of MCI to MIT in its formula is 3:1. This specific compounding ratio endows Euxyl K350 with efficient antibacterial properties, capable of inhibiting and killing various microorganisms.
Function
Wide antibacterial spectrum: Euxyl K350 has significant inhibitory effects on various microorganisms such as bacteria, mold, and yeast. Among them, it has strong killing ability against Gram positive bacteria and Gram negative bacteria such as Escherichia coli, Staphylococcus aureus, etc; It can also effectively inhibit the growth of common molds such as Aspergillus niger and Penicillium, as well as yeast such as Candida albicans.
Mechanism of action: Its antibacterial effect is mainly achieved by binding with biomolecules such as proteins and enzymes in microbial cells, interfering with the normal metabolic processes of microorganisms, disrupting the structure and function of cell membranes, and thus achieving the goal of inhibiting and killing microorganisms
Application
Euxyl K350 is used in a wide range of cosmetics, including skin care products (such as creams, lotions, serums, etc.), hair care products (such as shampoos, conditioners, etc.) and makeup products (such as foundation, mascara, etc.). It can effectively extend the shelf life of these products, prevent product deterioration, odor and performance degradation caused by microbial contamination, and ensure that consumers can use cosmetics safely and with confidence.
Usage and precautions
Usage: In the production process of cosmetics, Euxyl K350 is usually added in the final stage of the product to avoid potential activity reduction under processing conditions such as high temperature and high shear. The amount of addition is generally adjusted based on factors such as the type of product, formula composition, and expected shelf life, and is usually used at a concentration between 0.02% and 0.05%.
Caution: Due to the presence of MCI and MIT in Euxyl K350, these two components may cause allergic reactions in some populations. Therefore, strict safety assessments are required when using cosmetics containing this preservative, especially for people with sensitive skin. Meanwhile, during storage and use, contact with strong oxidants, strong acids, strong bases, and other substances should be avoided to avoid affecting their stability and antibacterial effect.
In different countries and regions, there are corresponding regulations and standards for the use of Euxyl K350. For example, the EU cosmetic regulations have strict restrictions on the use of MCI and MIT, stipulating that in resident cosmetics, the maximum allowable use concentration of MIT is 0.01% and the maximum allowable use concentration of MCI/MIT mixture (3:1) is 0.0015%. In rinse-off cosmetics, the maximum permissible concentration of the MCI/MIT mixture (3:1) is 0.003%. The U.S. Food and Drug Administration (FDA) also has regulations on the use of preservatives in cosmetics, and companies need to follow these regulatory requirements to ensure product safety and compliance.
