Antimicrobial Peptide P60.4Ac-Containing Creams and Gel for Eradication of Methicillin-Resistant Staphylococcus aureus from Cultured Skin and Airway Epithelial Surfaces. Antimicrob Agents Chemother. 2016 Jun 20;60(7):4063-72. doi: 10.1128/AAC.03001-15.
Abstract. The goal of this study was to identify the preferred carrier for this peptide for topical application on skin and mucosal surfaces.

Abstract. The preservation of solublized and emulsified disperse systems against microbial spoilage depends on the free (unbound) preservative concentration in the aqueous phase and the capacity of the system. The capacity may be defined as the system's ability to resist losses in free preservative concentration.

Abstract. The complexes of cetyl alcohol, cetomacrogol-1000, and water were successfully synthesized. The complexes were characterized by freeze-drying scanning electron microscopy, small-angle X-ray diffraction (SAXD), and ultra-SAXD. Furthermore, structures, electronic properties (the HOMO-LUMO gap, ionization potential, electron affinity, electronegativity, hardness, softness, dipole moment, and polarizability), and Raman spectra of cetyl alcohol, cetomacrogol-1000, and their binary and ternary complexes with water were also studied using density functional theory.

Abstract. Batch-to-batch variability is a challenge for the industrial scale production of ointments. Therefore the current investigation focussed on identifying and understanding critical process parameters (CPPs) for cetomacrogol ointment.

Abstract. Liquid paraffin-in-water emulsions prepared with cetomacrogol 1000 and alcohols cetostearyl (A), cetyl (B), steryl (C) and myristyl (D) were examined by microscopical, particle size analytical and rheological (continuous shear, small strain creep, and oscillation) techniques at 25 degrees as they aged over 30 days

Abstract. Using standard phage isolation techniques, ten phage capable of lysing P. acnes were isolated from human skin microflora. Their genomes showed high homology to previously reported P. acnes phage. These phage were formulated into cetomacrogol cream aqueous at a concentration of 2.5x108 PFU per gram, and shown to lyse underlying P. acnes cells grown as lawn cultures.

Abstract. Using a quality by design approach, upscaling can be based on the design space, which can be assessed on a small scale. In a previous study, the critical process parameters were identified by a definitive screening design on cetomacrogol ointment. In the current study, this lab scale (0.5 kg) study was scaled up to industrial scale (2000 kg, filling 100g tubes at 75 tubes/min).

Abstract. To investigate the efficacy of topical 90% medical-grade kanuka honey and 10% glycerine (Honevo) as a treatment for rosacea....Participants were randomly allocated 1:1 to Honevo or control cream (Cetomacrogol), applied twice daily for 8 weeks....

Cetomacrogol 1000 is a chemical compound, polyethylene glycol hexadecyl ether,
The name describes the structure of the molecule:
The synthesis process takes place in different steps:
Cetomacrogol 1000 appears as a white powder or white flakes or as a yellowish transparent liquid.
What it is used for and where
Cetomacrogol 1000 is a surfactant that is often used in cosmetics and pharmaceuticals for its ability to help water mix with oil and dirt, making it easier to clean skin and hair. The "1000" refers to the average molecular weight of the PEG portion of the molecule.
Pharmaceutical
An excipient in tablets and other pharmaceutical products as a solubiliser and emulsifier used in various topical formulations including ointments to combat Staphylococcus aureus. However, studies have found that in episodes of bacterial colonisation/infection of the skin, creams with Softisan and hypromellose as a gel performed better than Softisan with Cetomacrogol (1).
Solubiliser for poorly soluble drugs. Topical use: 0.5-5%.
Cosmetics
Solubilising and emulsifying agent for perfumes, essences, aromas. Primary decontaminating component for laundry detergents, shower gels.
Other uses
Studies
Cetomacrogol 1000 is produced industrially by the condensation of cetyl alcohol with ethylene oxide. With particular regard to ethylene oxide, in December 2018 the US Environmental Protection Agency (EPA) published an update on the safety assessment warning about the hazardous nature of exposure to this chemical compound which can cause, with short-term exposure, depression of the central nervous system and irritation of the eyes and mucous membranes and, with long-term exposure, irritation of the eyes, skin, nose, throat and lungs and damage to the brain and nervous system. The EPA has concluded that exposure to ethylene oxide increases the risk of lymphoid cancer and, for females, breast cancer (1). It should therefore be assessed whether there are any real risks to human health in the condensation process that results in the chemical compound Cetomacrogol 1000. Cetyl alcohol (hexadecan-1-ol) is a long-chain fatty alcohol used as a stabiliser in the production of Cetomacrogol 1000. No manufacturer appears to provide this information on the label, at least as of the date of this review.
