Description

[Technical Field]

[0001] The present disclosure relates to a personal care composition comprising: (a) a volatile alkane mixture, the alkane mixture comprising from about 10% to about 90% by weight of linear alkanes having 9 to 18 carbon atoms and from about 10% to about 90% by weight of branched alkanes having 10 to 14 carbon atoms, based on the total weight of the alkane mixture; and (b) one or more non-volatile oils selected from the group consisting of silicone oils, hydrocarbon oils, fluorinated oils, organic oils, and combinations thereof. The present disclosure also relates to linear alkanes comprising from about 0% to about 5% by weight of n-decane, from about 50% to about 80% by weight of n-dodecane, from about 1% to about 5% by weight of n-tetradecane, and from about 0% to about 5% by weight of n-hexadecane or n-octadecane, based on the total weight of the alkane mixture. The present disclosure further relates to a non-volatile oil selected from the group consisting of a conditioning agent, an emollient, a sunscreen oil, a natural oil, and combinations thereof. [Background technology]

[0002] Conditioning agents, emollients, sunscreen oils, and natural oils and esters are commonly used as functional oils in personal care applications to provide a moisturized, soft feel to hair, a gentle moisturizing feel to skin, UV protection, and nourishment, respectively. However, these non-volatile oils can have a heavy, oily, and sticky feel, which is undesirable. To achieve a light, dry sensation, these non-volatile oils must be delivered to the skin via a volatile carrier solvent. Currently used volatile solvents include silicone-based solvents such as cyclopentasiloxane and methyl trimethicone, or hydrocarbon-based solvents such as isododecane and isohexadecane. Silicone-based solvents present challenges due to their lack of biodegradability. Hydrocarbon-based solvents such as isododecane (IDD) evaporate too quickly from the skin, causing dryness and discomfort. Ester-based organic solvents or other hydrocarbon-based solvents, such as isohexadecane, are non-volatile and do not address the need for a non-greasy, non-sticky feel. Thus, there is a need to develop personal care formulations that contain solvents that can maintain the functionality and benefits of non-volatile oils and also provide a dry, non-greasy, non-sticky, and soft feel. The personal care compositions of the present disclosure provide these sensory benefits while retaining the functional benefits of non-volatile oils. Summary of the Invention
