Usage

Description

(Methylimino)diethane-1,2-diyl distearate, also known as MDDS, is a chemical compound that serves as an emollient and skin conditioning agent in the cosmetic and personal care industry. Derived from the reaction between stearic acid and diethanolamine, MDDS is recognized for its moisturizing and protective properties for the skin.

Uses

Used in Cosmetic and Personal Care Industry:
MDDS is used as an emollient and skin conditioning agent for its ability to moisturize and protect the skin. It is particularly valued for its smooth and creamy texture, which enhances the spreadability and feel of cosmetic and personal care products such as lotions, creams, and lipsticks.
Used in Lotion and Cream Formulations:
In the formulation of lotions and creams, MDDS is used as a key ingredient to provide a luxurious, smooth texture and improve the skin's hydration levels. Its emollient properties help to soften the skin, making it an ideal component for these types of products.
Used in Lipstick Production:
MDDS is also utilized in the production of lipsticks, where it contributes to a desirable texture and application experience. Its ability to enhance spreadability ensures that the lipstick glides on smoothly, while its moisturizing effect helps to keep the lips hydrated and conditioned.

Synthesis, Surface Properties, and Antibacterial Activity of Novel Ester-Containing Cationic Silicone Surfactants and Their Utilization as Fabric-Finishing Agents

In this study, a series of cationic silicone surfactants SiQCnCl containing ester groups and double long-chain alkyls (n = 9, 11, 13, 15, and 17) were synthesized by microwave irradiation and characterized using infrared Fourier transform (FTIR), 1H nuclear magnetic resonance (1H NMR), and thermogravimetric analysis (TGA). Surface activity and adsorption of these surfactants were investigated by measuring the equilibrium surface tension. The critical micelle concentration (CMC) decreased with increasing alkyl length of SiQCnCl at 25 °C and so did the corresponding surface tension at the CMC (γCMC). The aggregation behavior in aqueous solutions was also investigated systemically through transmission electron microscopy (TEM) and dynamic light scattering (DLS). Spherical or ellipsoidal-like aggregates with diameters ranging from 300 to 900 nm were observed. It is also shown that the cationic silicone surfactants exhibit certain antibacterial properties against Staphylococcus aureus but slightly poor to Escherichia coli. The morphological structure of SiQC15Cl-treated cotton fabrics was observed using scanning electron microscopy (SEM), which showed that the surface became neat and smooth. What is more, the finished cotton fabrics maintained some antibacterial properties with improved softness, which may provide a more comfortable and healthy lifestyle. This work may also be helpful to the design and application of functional cationic silicone surfactants.

SATURATED AND POLYMERIZABLE AMPHIPHILES WITH FLUOROCARBON CHAINS. INVESTIGATION IN MONOLAYERS AND LIPOSOMES.

The synthesis and characterization of several saturated and polymerizable amphiphiles with fluorocarbon chains are described. Monolayers of lipids containing fluorocarbon chains are more stable than those formed from their hydrocarbon counterparts. The creation of phase-separated monolayers and liposomes is possible when the membrane is composed of a mixture of lipids containing hydrocarbon chains and lipids containing fluorocarbon chains. Phase separation even occurs when the two lipids bear the same head group. Complete phase separation of a natural lipid (DMPC) and a lipid with fluorocarbon chains, 1, could be demonstrated in liposomes by using freeze-fracture electron microscopy. Phase separation was even confirmed when the percentage of the fluorocarbon amphiphile was as low as 5 mol%. The polymerization behavior of unsaturated amphiphiles with fluorocarbon chains was investigated in monolayers and liposomes.
