The lower pH preserves the stability of the allantoin and the functionality of the emulsifier system is maintained. The emulsifier system can be a nonionic emulsifier or an anionic emulsifier plus beeswax. The acid used to adjust the pH can be an organic acid or an inorganic acid. The emulsion can further comprise other ingredients such as herbal extracts, chelating agents, preservatives, emollients, solvents, and fragrance.

  • Patent number: 6831107
    Abstract: Personal care or cosmetic oil in water emulsions include an oil emulsifier and a combination of a Xanthan polysaccharide and a polyglucomannan polysaccharide to provide enhanced stability even at low emulsifier stabiliser levels. The emulsifier stabiliser system provides stable emulsions without dominating system rheology, particularly viscosity. Thus, the emulsions can have a low viscosity suitable for formulation as milks or thin lotions, or can be thickened, desirably by thickening agents other than the Xanthan and/or polyglucomannan, to provide emulsion creams or gels. This enables the system to be used very flexibly in end use applications. The emulsifier is desirably a non-ionic emulsifier and particularly is a combination of a low HLB and a high HLB emulsifier and can be formulated with conventional alcohol ethoxylate surfactants or from non-EO surfactants e.g. sucrose ester high HLB surfactants and citrate or sorbitan ester low HLB surfactants.

  • Patent number: 6783766
    Abstract: The present invention is a process of preparing an advanced cosmetic product by combining a high internal phase ratio (HIPR) emollient-in-water emulsion with a partial cosmetic formulation that typically contains water, fragrance, a rheology modifier, or a pH adjuster, or a combination thereof. The present invention is also a composition comprising two particular subclasses of HIPR emollient-in-water emulsions, namely an HIPR silicone elastomer-in-water emulsion and an HIPR sunscreen-in-water emulsion. The use of an HIPR emulsion of a cosmetic emollient provides a simple and flexible method of formulating the cosmetic product, due in part to the long shelf-stability of the HIPR emulsion (>1 year), and the low quantity of water in the emulsion (typically less than 20% by volume based on the volume of emollient and water).

  • Patent number: 6673826
    Abstract: An improved method of treating skin diseases comprises applying to the skin of a patient suffering such a skin disease an allantoin-containing composition in a therapeutically effective quantity. The allantoin-containing composition is a water-in-oil emulsion that includes allantoin and an emulsifier system that includes at least one emulsifier that is either an anionic emulsifier or a nonionic emulsifier. If the emulsifier is an anionic emulsifier, the emulsifier system can include beeswax. The nonionic emulsifiers used can include at least one nonionic emulsifier that is an ethoxylated ether or an ethoxylated ester whose carbon chain length ranges from 8 to 22 carbon atoms. Alternatively, the emulsifier system can include an acidic anionic polymer such as carboxypolymethylene and an anionic emulsifier. In another alternative, the emulsifier system can include the acidic anionic polymer and a nonionic emulsifier, or the acidic anionic polymer alone.

  • Patent number: 6541018
    Abstract: The present invention provides a nanoemulsion, that includes: an oily phase dispersed in an aqueous phase; and at least one glycerol fatty ester surfactant which is solid at a temperature of less than or equal to 45° C.; wherein the oily phase includes oil globules having a number-average size of less than 100 nm; wherein the oily phase includes at least one oil having a molecular weight of greater than 400; and wherein a weight ratio of the oily phase to the surfactant ranges from 2 to 10. The invention also provides a process for making the nanoemulsion and methods for its use. Ideally, the emulsion is transparent and stable on storage. It can ideally contain large amounts of oil while retaining good transparency and good cosmetic properties. The nanoemulsion is particularly useful in the cosmetics and dermatological fields, in particular for moisturizing the skin and/or mucous membranes, as well as for treating the hair, and, in the ophthalmological field, as an eye lotion for treating the eyes.
