摘要:
Spray compositions and particularly anhydrous aerosol compositions containing particulate antiperspirant actives exhibit a tendency for nozzle blockage, impeding discharge of the contents when a polyol humectant, such as glycerol, is blended into its base composition. The problem is overcome or at least ameliorated by preparation of a base composition, suitable for employment in conjunction with a propellant, that contains a low molecular weight (liquid) polyethylene glycol (PEG) as humectant, and particularly a PEG of molecular weight 150 to 500.
摘要:
Incorporation of a polyol humectant in an anhydrous composition containing an astringent aluminium and/or zirconium antiperspirant salt can result in grit formation and hence poor sensory properties unless the polyol is prior contacted with a perfume carrier. A simpler manufacturing process that enables the composition to retain its moisturising properties employs 20 to 90% of a carrier oil plus up to 10% of a liquid, low molecular weight polyethylene glycol as humectant, preferably having an average molecular weight of from 190 to 600, not prior complexed with the antiperspirant salt.

摘要:
A test method is described for comparing the relative affinity of products for a target substance using a substrate ordinarily and visibly sensitive to the products. The test method is useful in one embodiment for comparing the ability of harsh cleansers to remove fatty acids from the skin with mild cleansers that do not remove fatty acids to the same extent using a visually compelling substrate, such as a fresh cut flower.
摘要:
Liquid lamellar cleansing compositions are described that contain synthetic surfactants, hydrophilic emollients and exfoliant particles where 80% or more of the particles have a major axis length of between 100 and 1000 microns. The combination of the mild surfactants, moisturizers, and exfoliants provide the user with simultaneous moisturization and exfoliation in a convenient liquid cleansing product.
摘要:
Composition may be prepared in a single DEFI reactor comprising mixtures of (1) DEFI (directly esterified fatty acyl isethionate) and (2) a compound produced by the reaction of (a) isethionate with a fatty acid replacement (e.g., a multicarboxylic fatty acid, a fatty acid); or (b) fatty acid with an isethionate replacement (e.g., C2-C24 alcohols, C2-C20 organic acids, amines). Such mixtures are milder than DEFI alone while retaining substantially same foaming benefit.
摘要:
The present invention is directed to mixed fatty acid soap based bar compositions, which may include synthetic surfactants as co-actives, wherein relatively small amounts of specified polyoxyethylene-polypropylene nonionic polymer has been found to enhance mildness and reduced mush of bar compositions without sacrificing the user properties and processability of the formulations.
摘要:
An antiperspirant composition is disclosed in the form of a transparent stick. The composition comprises a mixture of aluminum chlorohydrate, nonionic surfactant, liquid oil, and water, the latter being present in an amount from 20 to 50%. Preferably, the liquid oil is a combination of volatile silicone and emollient oil.

摘要:
The invention relates to a process for making single phase dilution thickening compositions comprising electrolyte. By adding defined associative thickener to said compositions applicants have found one can lower level of salt/electrolyte required to obtain dilution thickening effect.
