Description

BIOBASED ADDITIVE FOR PERSONAL CARE PRODUCTSCROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is related to U.S. Provisional Application Serial No. 63 / 504,971 filed May 30, 2023 entitled “BIOBASED ADDITIVE FOR PERSONAL CARE PRODUCTS,” which is incorporated herein by reference in its entirety for all purposes.FIELD

[0002] The present disclosure relates generally to biobased additives. More particularly, the present disclosure relates to biobased additives for use in personal care products.BACKGROUND

[0003] Multifunctional, environmentally-friendly, and non-toxic products are in high demand. For personal care product manufacturers, there are two critical areas that will be impacted by rising consumer demand for the aforementioned characteristics: (i) recipe formulation and (ii) ingredient traceability. Many personal care brands are evolving their product composition to incorporate more natural and ethically-harvested ingredients. Additionally, personal care brands are increasingly focusing on authenticity in marketing their clean credentials.

[0004] Conventional additives used in personal care products, while effective, often (i) are not biodegradable, (ii) are biodegradable but utilize harmful additives, or (iii) are biodegradable but exhibit inadequate performance. For example, ethylenediaminetetraacetic acid, EDTA, a common chelating agent, is known to be a persistent pollutant in the environment. Common chelating agents are not biodegradable and tend to lead to the mobilization and bioavailability of heavy metals. Furthermore, for example, free EDTA is shown to produce adverse reproductive and developmental effects in mammals. Thus, an ongoing need exists for additives that improve the performance of personal care products.BRIEF DESCRIPTION OF THE FIGURES

[0005] The following figure forms part of the present specification and is included to further demonstrate certain aspects of the present disclosure. The subject matter of the present disclosure may be better understood by reference to the figure in combination with the detailed description of specific aspects presented herein.

[0064] The utilization of a BBA of the type disclosed herein in a gel moisturizer formulation was investigated. An oil-free polyhydroxy acid (PHA) gel moisturizer was formulated that contained a BBA .specifically a sugar oxidation product. The PHA gel moisturizer was prepared by blending individual components of the gel moisturizer separately to form mixtures that were then incorporated into the final formulation. The individual components were blended to form Phase A which contained the BBA and water, Phase B which contained propanediol and xanthan gum and Phase C which contained silica.

[0065] The final formulation was prepared by premixing phase B and then adding the premixed phase B to phase A with agitation (e.g., fast propeller stirring) until the mixture was uniform. Phase C was then added to the uniform mixture with agitation until the mixture was uniform. This mixture was designated Formulation 1 . The cosmetic benefits of Formulation 1 include but are not limited to: (i) line blurring and aesthetic enhancement; (ii) exfoliation and moisturization activity and (iii) a smoothing effect such that the formulation can act as a makeup primer. The component list is presented in Table 1 .Table 1EXAMPLE 2

[0066] The utilization of a BBA of the type disclosed herein in a cream formulation was investigated. Specifically, a brown sugar PHA cream was formulated by creating 3 phases. Phase A contained water and a BBA, Phase B contained a triglyceride, an alcohol and a sulfosuccinate; and Phase C contained propanediol, silica , a phosphate, an acid, glycerol, a surfactant, and natural extracts. This formulation was designated Formulation 2, and the specific amount of these components listed in Table 2.Table 2

[0067] Formulation 2 was prepared by heating phases A and B to 75 °C; phase B was added to phase A with agitation (e.g., fast sharp-bladed stirring) to form a mixture. Phase C, which was premixed, was added to the mixture and homogenized until uniform to generate Formulation 2.EXAMPLE 3

[0068] The utilization of a BBA of the type disclosed herein in a facial cleanser was investigated. Specifically, a brown sugar facial cleanser was formulated by creating 3 phases. Phase A contained water and a BBA, Phase B contained water, a sulfonate, ,an alcohol and a sulfosuccinate; and Phase C contained propanediol, silica , a betaine and a stearamide and Phase C contained sodium chloride. This formulation was designated Formulation 3, and the specific amount of these components listed in Table3.Table 3

[0069] Formulation 3 was prepared by premixing phase A and phase B which was subsequently stirred, by hand or using a round propeller to form a mixture. Phase C was slowly added to the mixture until the desired viscosity was reached. Formulation 3 functioned as a gentle face cleanser.EXAMPLE 4

[0070] The utilization of a BBA of the type disclosed herein in a soap formulation was investigated. The specific components and the amount of each component are present in Table 4. The table presents the amount of each component relative to the amount of the active which is set as 100%. BBA 1 contained a single sugar oxidation product while BBA2 contained a mixture of gluconic and glucaric acids.

[0071] Table 4

[0072] The soap was prepared adding water to the surfactants (e.g., hydroxysultaine) and mixing to form a surfactant solution. Glycerin and extracts (e.g., fruit oil) was then added to the surfactant solution and agitated to form a mixture. Acids, sorbate and benozate was added to the mixture to form a second mixture. The pH of the second mixture as adjusted by addition of an acid (e.g., hydrochloric acid) to second mixture to adjust the pH to approximately 5.0.

[0073] Experiment: Preservation study with BBA

[0074] The ability of a BBA of the type disclosed herein to function as a preservative was investigated. Specifically, a BBA was used as an alternative to EDTA in order to sequester cations and preserve formulations such as soaps. Each sample contained sodium tallowate, sodium cocoate, or sodium palm kernelate, water, sodium chloride, sodium silicate and magnesium sulfate and either no additive (control), EDTA, a mixture of glucaric acid and gluconic acid (GOGA) or gluconic acid (LG60). The samples were aged at 45 °C for eight weeks and the samples assessed weekly.

[0075] As shown in Table 5 below, the formulation containing a BBA (e.g., GOGA) was comparable to EDTA’s preservation performance. The dosage of each chelate was 0.4% active product.Table 5
