  • Patent number: 6682749
    Abstract: This invention comprises low residue cosmetic compositions (especially underarm products) which are made by combining an active ingredient; a silicone gel material itself comprising an elastomer composition; and at least one selected surfactant having an HLB value in the range of 8-16. The compositions of this invention exhibit reduced or eliminated film formation when applied to the skin and increased availABILity of the active ingredient.

  • Patent number: 6180125
    Abstract: This invention comprises a one-phase cosmetic composition which is a clear stick or gel having low tack. The cosmetic sticks are formed as a one phase system by combining: (a) from 0.5-50 weight percent of a dimethicone copolyol ester compound soluble in propylene glycol; (b) from 50-99 weight percent of a gellant/solvent system; which comprises a mixture of: (i) 0.5-4.0 weight percent dibenzylidene sorbitol; (ii) 0.05-1.0 weight percent of a co-gellant or structural integrity enhancer; (iii) 0.

  • Patent number: 6180121
    Abstract: This invention relates to fragrance enhancing compositions which are capable of controlling malodor from a human body to a significant extent thereby reducing the overall amount of fragrance required to achieve a satisfactory cosmetic product, especially an underarm product. The fragrance enhancing compositions of this invention are made by combining at least three components from a selected group of non-nitromusk materials.

  • Patent number: 6156826
    Abstract: Described are controlled, time-release microparticulate active and bioactive compositions (including perfuming compositions) for targeted delivery to surfaces such as skin, hair and fabric and the environment proximate thereto, where the active and bioactive materials have a calculated log.sub.10 P values of between 1 and 8 (P being the n-octanol-water partition coefficient). Such compositions include the active or bioactive material in single phase, solid solution in a wax or polymer matrix also having coated thereon and/or containing a compatible surfactant. Also described are processes and apparatus for preparing such compositions and processes for using same. Furthermore, certain component(s) of the aforementioned compositions in combination with one another are novel, and other components have novel uses in increasing fragrance substantivity, particularly in hair care preparations such as hair gels and shampoos.

  • Patent number: 6036964
    Abstract: Cosmetic compositions are disclosed which are made from a multi-component base made from at least three different components, which base exhibits a weight loss not exceeding 46% in a 24 hour period in a controlled environment with minimum air flow in a humidity chamber with a temperature of 35-40 degrees C. and 80% humidity; and a medium volatility fragrance, wherein a solubility parameter is calculated for each of the base and fragrance components are matched so that the difference between them is less than 38%.

  • Patent number: 5506201
    Abstract: A method is disclosed for producing a fragrance containing solid particle for incorporation into laundry detergent by selecting a fat component such as a fatty acid glyceride, heating said fat component to an elevated temperature sufficient to form a molten melt thereof, selecting a solid surface active agent from the group consisting of SPAN.RTM. surfactants with an HLB of 4.3 to 8.6, heating the surface active agent to form a molten melt thereof and then combining the melts with an aroma chemical to form a mixture. The melt is rapidly cooled to form a solid material.

  • Patent number: 5468725
    Abstract: An alcohol-free transparent perfume is disclosed containing an alcohol-free perfume base, water and a stable transparent oil-in-water microemulsion flavor concentrate formed of water, at least one hydrophobic perfume oils, at least one cationic surfactant and at least one non-ionic surfactant in the absence of lower alkanols wherein the mixing ratio of water, oil and surfactant is defined according to the shaded area of FIG. 1.

  • Patent number: 5447644
    Abstract: A method is disclosed for controlling the viscosity of fabric softener compositions to thereby improve shelf life by first forming a microemulsion of a perfume and a surfactant by mixing a perfume and a surfactant at a temperature where each component is in the liquid state. Sufficient shearing forces are used to uniformly disperse the perfume in the surfactant to form a stable microemulsion of said perfume in said surfactant. The microemulsion is then mixed with a fabric softener base formulation.

  • Patent number: 5413723
    Abstract: Control of fabric softener viscosity by increasing the amount of fragrance in the formulation and to thereby influence the amount of fragrance that can be added to the fabric softening formulations. A mixture of a perfume or fragrance chemical and special group of surface active agents is prepared. Thereafter the mixture is added to a fabric softener base formulation to produce the fabric softener consumer product.
