Problems solved by technology

[0005] Although these microcapsules are capable of encapsulating and delivering multiple benefit agents to the hair, it has been difficult to improve the retention and delivery efficiency of such benefit agents
Such agents may be lost due to the physical or chemical characteristics of the agent, may be washed from the hair during rinsing, or may be incompatible with other constituents already present in the hair

[0074] Microcapsules

[0075] The conditioner composition comprises polyacrylate microcapsules, preferably a plurality of polyacrylate microcapsules. The conditioner composition comprises from 0.004% to 10%, preferably from 0.01% to 8%, more preferably from 0.1% to 5%, or even more preferably from 0.25% to 3%, by weight of the conditioner composition, of polyacrylate micro capsule. The polyacrylate microcapsules comprise a core material and a shell material encapsulating the core material, and the core material is disposed within the shell material. The shell material comprises a polyacrylate polymer and the core material comprises a benefit agent. The polyacrylate microcapsules may contain anionic emulsifiers.

[0076] Preferred microcapsules comprising shell materials comprising polyacrylate materials are described in detail in US Patent Application Serial No. 62 / 206,971 (case 13998P).

[0077] The polyacrylate microcapsules will generally have a volume weighted median...

Embodiment

[0351] Example: Weight of empty beaker and stirrer = 125.0 g

[0352] % solids of PVOH = 97.50% or 0.9750, final weight in decimal = 125.0 + (0.9750 x 400) = 515.0 g

[0353] Zero the top load balance and place the beaker and propeller of PVOH solution on it. Add deionized water to bring the weight to the calculated final weight.

[0354] A sample of the 4% PVOH solution was dispensed into the chamber of the viscometer, and the spindle was inserted and attached to the viscometer. Sample adapter (SSA) with chamber SC4-13RPY, Ultralow adapter. The mandrels are SC4-18 and 00. The samples were allowed to equilibrate at a temperature of 20 °C. Start the viscometer and record the steady state viscosity value.

[0355] Determine the solids content.

[0356] Weight % solids in decimal = solids content of sample should be 4.00 + 0.05% to calculate viscosity.

[0357] Report viscosities < 13 cP to the nearest 0.01 cP, 13 cP to 100 cP to the nearest 0.1 cP; report viscosities over...

Abstract

Described herein, a conditioner composition can help to provide improved long-lasting odor benefit of the benefit agent containing polyacrylate microcapsules onto hair. The conditioner composition includes a combination of polyacrylate microcapsules, deposition polymers, conditioner agents, and a carrier.

Description

technical field [0001] This patent application generally relates to conditioner compositions comprising polyacrylate microcapsules, wherein the polyacrylate microcapsules have improved long-lasting odor benefits. Background technique [0002] Many conditioner products currently on the market serve to deliver benefits to the hair by depositing benefit agents such as fragrances and conditioning agents onto the hair during conditioning. Therefore, it is desirable to maximize the effect of such benefit agents by enhancing their delivery and retention on the hair. [0003] In particular, such benefit agents may please the user by providing a sense of refreshment and may function to signal to the user that the product may still be functional or that the product is still present. But because of the volatility of many fragrances, consumers may not notice the fragrance shortly after application of the consumer product, potentially leading the user to believe that the benefit is wear...
