Sumitomo Seika Chemicals Co., Ltd. announced the launch of electrolyte resistance and polymeric emulsifier type AQUPEC granule grade (800ERK series) and super electrolyte resistance type AQUPEC (SERK series), which are new types of high functional rheology modifiers (thickeners) of acrylic water-soluble resin (trade name "AQUPEC").
AQUPEC granular grade (800 series; INCI Name: "Carbomer") is acrylic water- soluble resin which is produced from raw materials selected with safety in mind and provides users with greatly improved usability and working environment. This 800 series was officially put on the market in spring this year and since then, orders have been increasing. In light of such a favorable reaction from the market, we have decided to expand our product line by creating new products which have ideal rheology properties meeting customers' needs.
Features of each new series are as follows:
Electrolyte resistance and polymeric emulsifier type AQUPEC granular grade (800ERK series) (INCI Name: Acrylates/C10-30 Alkyl Acrylate Crosspolymer)
By way of application of their proprietary granulation technology for acrylic water-soluble resin, the new product is designed to have a function of easy dispersibility without using a general type nonionic emulsifier which was mixed in a conventional product to prevent formation of lumps. Due to this feature, this series can be used for products which need to suppress or avoid the use of emulsifier (such as gel or cream type skin care products).
This product has emulsification ability as a result of copolymerization of acrylic acid (hydrophilic) and alkyl acrylate (hydrophobic). Due to this feature, users can reduce the used amount of low molecular emulsifier.
Super electrolyte resistance type AQUPEC (SERK series) (INCI Name: Acrylates/C10-30 Alkyl Acrylate Crosspolymer)
Usually viscosity of acrylic water-soluble resin lowers substantially when electrolyte gets in.
In contract, SERK series is peculiar enough to develop viscosity in the presence of electrolyte. Due to this feature, this series can be used for such applications as contain electrolyte that is not compatible with conventional acrylic water-soluble resin. In addition, this series has a feature to emulsify so large an amount of oil that it can widely be used for milky liquid or cream.
Despite that SERK series is acrylic water-soluble resin, it keeps viscosity and transparency even in the presence of electrolyte. This product has emulsification ability as a result of copolymerization of acrylic acid (hydrophilic) and alkyl acrylate (hydrophobic). Due to this feature, users can reduce the used amount of low molecular emulsifier.
