Towards satisfying performance of an O/W cosmetic emulsion: screening of reformulation factors on textural and rheological properties using general experimental design
The aim of the study was to evaluate the influence of multiple factors – variations of the composition, manufacturing conditions and their interactions, on emulsion textural and rheological characteristics, applying the general experimental factorial design and to establish the approach that could replace, to some extent, certain expensive and time‐consuming tests after the reformulation.
Low-energy nanoemulsions as carriers for red raspberry seed oil: Formulation approach based on Raman spectroscopy and textural analysis, physicochemical properties, stability and in vitro
It was shown that low-energy nanoemulsions present very promising carriers for topical delivery of natural bioactives, and Raman spectroscopy and textural analysis have proven to be a useful addition to the arsenal of methods used in the formulation and characterization of nanoemulsion systems.
Diffusion of drugs in hydrogels based on (meth)acrylates, poly(alkylene glycol) (meth)acrylates and itaconic acid
The diffusion coefficient of drugs and the restriction coefficient, λ, defined as the ratio of solute to “pore” radius that describes the ease of drug release from the gels, were used as factors that govern the release process.
Feasibility of a Natural Surfactant as a Stabilizer for Cosmetics with Liposome-Encapsulated Plant Stem Cells: Pre-Formulation and Formulation Through Stability Studies
Abstract During the formulation of liposome-containing products different problems can occur and the selection of a suitable carrier remains the greatest challenge. To estimate feasibility of a novel
Formulation of topical acidic products and acidification of the skin – Contribution of glycolic acid
Aim of this work was to investigate formulations of acidic topical products with glycolic acid stabilized with long chain alkyl polyglucoside emulsifier, in regard to the specific colloidal structure of the vehicle, together with effect of products with different concentration of acidic active on skin pH.
Alp Rose stem cells, olive oil squalene and a natural alkyl polyglucoside emulsifier: Are they appropriate ingredients of skin moisturizers - in vivo efficacy on normal and sodium lauryl sulfate -
The in-vestigated actives incorporated into alkyl polyglucoside emulsi-fier-stabilized creams may be safely applied as ingredients for "tailor-made" cosmetic moisturizers intended for normal and dry skin care, whereas olive oil squalene could be used for the treatment of irritated or sensitive skin as well.
Immobilization of lipase from Candida rugosa into copolymer hydrogels of poly(N-isopropylacrylamide-co-itaconic acid) synthesized in the presence of surfactants
It was concluded that the addition of surfactants increased the hydrogel mesh size and did not affect the dynamic - mechanical properties of the investigated hydrogels.
Synthetic lubricants based on copolymers of n-butyl methacrylate and α-olefins
Synthetic fluids obtained by the copolymerization of α -olefins with alkyl esters of unsaturated carboxylic acids have a unique combination of properties of non-polar poly-a-olefins (PAOs) and polar
Synthesis and characterization of copolymer hydrogels of chitosan, itaconic acid and N-isopropilacrylamide
This paper deals with synthesis of copolymer hydrogels of N-isopropilacrylamide, itaconic acid and chitosan. During synthesis, pH of the reaction solution and temperature were varied. It was
