FMEE/MEE generally refers to fatty acid methyl ester ethoxylates or methyl ester ethoxylates, also known as ethoxylated fatty acid methyl esters. FMEE is a type of nonionic surfactant and belongs to the class of ether-ester surfactants produced by the ethoxylation of fatty acid methyl esters ...
Nitrate reduction is a key reaction in the biological nitrogen cycle that determines the fate of NO₃⁻. After NO₃⁻ is reduced to NO₂⁻, it can enter denitrification, DNRA, or assimilatory utilization pathways, which respectively affect nitrogen removal, nitrogen retention, and biomass ...
The same red color can appear in lipstick, shower gel, liquid foundation, and color-changing lip balm, but the formulation logic behind it is not the same. In lipstick, red colorants need to be evaluated for color payoff, coverage, color retention, and bleeding risk. In a transparent shower gel, ...
In the household and personal care chemical industry, the system more closely related to SDBS and more widely used in practical applications is linear alkylbenzene sulfonate, abbreviated as LAS. LAS is a mixture of homologues and isomers composed of alkylbenzene sulfonates with different ...
When laundry detergent is dropped onto fabric, if the liquid remains only on the fiber surface, soils inside the fiber structure are difficult to contact sufficiently. When a kitchen cleaner is sprayed onto an oil film, if the droplets bead up, the alkali and surfactants can hardly act uniformly ...
In home-care cleaning formulations, citric acid is often understood simply as an ingredient used to adjust pH, that is, acidity or alkalinity. This understanding is incomplete. The value of citric acid lies not only in adjusting the pH of a system, but also in its ability to contribute to ...
In household and personal-care cleaning systems and water-based emulsification systems, many formulation challenges arise from the same contradiction: oily substances do not readily enter the aqueous phase, whereas most cleaning systems use water as the continuous phase. Water can remove ...
Butylene glycol and propylene glycol are commonly used in skincare products, cleansing products, and color cosmetics. They are often classified as humectants, but understanding these ingredients only from the perspective of “moisturization” underestimates their actual value in formulations.
The opacity of daily chemical products comes from microstructures formed within the formula that can affect the propagation of light. When light enters a system, if it can pass through relatively smoothly, the product appears transparent or translucent. If light continuously encounters ...
