摘要:
The present invention is directed to compositions, particularly cosmetic compositions, in which the oil is thickened using at least one copolymer which has a hydrophobic functionality sufficient to provide at least partial solubility and optionally stability in oil and a hydrophilic functionality sufficient to provide thickening of the oil. Use of such copolymers as thickening agents are advantageous in that they are soluble and stable in the oil phase. Further, sufficient thickening may be accomplished using very low amounts of these copolymers without the use of additional polymeric thickeners.

Hair spray compositions in aqueous based systems containing 80% or less of volatile organic compounds exhibit a loss of spray performance properties resulting from viscosity and surface tension increases. The addition of 0.6 to 5% of one or more hydrophobic additives selected from the group consisting of hexamethyl disiloxane, bisphenyl hexamethicone and isocetyl alcohol improves the spray characteristics by eliminating foaming at the spray actuator and on the hair.
摘要:
The present invention is directed to a low VOC, non-aerosol, polyacrylic acid containing hair cosmetic compositions which contain stabilized starches, particularly those derivatized by alkylene oxides, about 01.-0.0% polyacrylic acid, up to about 15% solvent, and water. The derivatized starch may be hydrolyzed, particularly enzymatically hydrolyzed by at least one endo-enzyme. In addition, the starch may be cationically modified with a low degree of substitution. Use of such starches is novel and advantageous in that they are compatible with polyacrylic acid, providing a clear, solution with a stable viscosity. Further, the resultant composition provides a clear film which is not tacky, good stiffness, and improved humidity resistance.
摘要:
The present invention relates to hair care compositions which contain a polymer which is prepared from N-vinyl formamide (NVF) monomer and the use of those hair care compositions to treat hair. The polymer may be a homopolymer of NVF or an interpolymer of NVF and at least one vinyl monomer. The polymer is present in amounts effective to provide the hair care compositions with hair fixative properties and/or hair conditioning properties.

摘要:
Polysaccharide esters containing aldehyde and acetal groups having the structural formulas ##STR1## are prepared by reacting a polysaccharide, such as a starch, gum, or cellulose, with an acetal-containing reagent which contains a functional group reactive with the hydroxyl groups of the polysaccharide; Z is a multivalent organic group: A and A' are independently a lower alkyl or together form at least a 5-membered cyclic acetal; x is at least 1; and y is at least 1. When x is >1 the esters are crosslinked. Typical reagents for introducing the acetal group include 3,3-diethoxypropionyl guanidine (itself a novel compound) and 4-(methylaminoacetaldehyde dimethyl acetal)-4-oxo-butanoic acid). The derivatives are useful in conventional applications such as coatings, adhesives, paper additives and foodstuffs.
摘要:
Film-forming compositions comprising a film forming polymer containing acid groups and a neutralizing agent; compositions and methods for increasing the SPF of a composition by neutralizing at least a portion of the acid groups of the film forming agent with the neutralizing agent.
摘要:
This invention involves skin cleaning products and tapes for removing keratotic plugs, dirt and other debris found on the skin and in skin pores and comprising a starch based remoistenable adhesive composition wherein the starch has from about 0 to 70% by weight amylose content and is converted to from about 30 WF to 20 DE.
摘要:
Low molecular weight polyaldehydes are prepared by converting the acetal groups of the low molecular weight polyacetal to aldehyde groups or by reacting an aldehyde-containing reagent (e.g., glyoxal) with a polyamide.
摘要:
Low molecular weight polyacetals are prepared by reacting an acetal-containing reagent with a polyalcohol (e.g., glycerol or sucrose), a polyamine (e.g., 3,3'-diamine-N-methyl dipropylamine or ethylene diamine), a polyester (e.g., triethyl citrate), or a polyhalide (e.g., pentaerythrityl tetrabromide). Low molecular weight polyaldehydes are prepared by converting the acetal groups of the low molecular weight polyacetal to aldehyde groups or by reacting an aldehyde-containing reagent (e.g., glyoxal) with a polyamide.
