example 1

[0062] An in vitro study was performed on a keratinocyte skin model to determine the efficacy of different concentrations of hemp seed oil (HSO) and / or flax seed oil (FSO) on the production of antimicrobial peptides (AMPs). AMP production was determined by measuring the presence of an AMP biomarker, LL-37. It is understood that AMPs, also known as host defense peptides, are part of the innate immune response. AMP has demonstrated efficacy as a therapeutic agent and has further demonstrated its ability to treat, reduce or eliminate gram-negative and gram-positive bacteria, including conventional antibiotics, mycobacteria, enveloped viruses, fungi, and transformed Those bacteria to which cells or cancer cells are resistant. From the foregoing, it is understood that AMPs provide protection of the epithelial surface or skin against environmental microorganisms.

example 2

[0074] An in vitro study was performed on a keratinocyte skin model to observe the production of interleukin 1α (IL-1α) in the presence of various concentrations of HSO and / or FSO. It will be appreciated that IL-1α, also known as hematopoietin 1, is a cytokine of the interleukin 1 family encoded by the IL1α gene. It is further understood that interleukin 1 is responsible for the production of inflammation and irritation and is widely regarded as a biomarker for assessing skin irritation.

[0075] To assess IL-1α production, keratinocyte skin models were grown to at least 60% confluence and placed in corresponding wells of well plates. Stock solutions of FSO and HSO were prepared analogously to Example 1. Specifically, 100% FSO was combined with 100% dimethyl sulfoxide (DMSO) in a ratio of about 1:99, thereby preparing a 1% solution of FSO in DMSO. Similarly, a 1% solution of HSO in DMSO was prepared by combining HSO with 100% DMSO in a ratio of about 1 :99. A vehicle stock ...

[0089] A similar in vitro study to Example 2 was performed on a keratinocyte skin model to observe the production of interleukin 1α (IL-1α) in the presence of various concentrations of cannabis HSO and / or FSO. The stock solution prepared in Example 2 was used in the study. The stock solutions were used to prepare eight samples (15)-(22) with varying amounts of FSO and / or HSO. The amounts or concentrations of each of the samples (15)-(22) are summarized in Table 6. A brief description of each of the samples (15)-(22) is summarized in Table 7.

Abstract

Personal care compositions and methods for increasing the amount of antimicrobial peptides produced by the skin, reducing skin inflammation, reducing skin irritation, reducing reactive oxygen species in the skin, or any combination thereof are disclosed. The personal care composition may include a carrier and at least two vegetable oils. The at least two vegetable oils may be present in an amount effective to increase the amount of antimicrobial peptides produced by the skin, reduce skin inflammation, reduce skin irritation, reduce reactive oxygen species in the skin, or any combination thereof.

Description

Background technique [0001] Personal care compositions can often incorporate beneficial components or beneficial agents for imparting benefits or properties to the composition. For example, skin care compositions can often incorporate antimicrobial agents for imparting antimicrobial properties to the composition. Similarly, skin care compositions can often incorporate antioxidants for imparting anti-aging properties to the composition. While the incorporation of these beneficial agents has demonstrated efficacy in enhancing the corresponding properties of personal care compositions, the search for new beneficial agents that exhibit improved or multiple benefits is still ongoing. [0002] There is, then, a need for personal care compositions and methods of incorporating improved beneficial agents with multiple beneficial properties. SUMMARY OF THE INVENTION [0003] This Summary is merely intended to introduce a simplified summary of some aspects of one or more implementati...
