The present invention relates to the use of phenyl ketone derivatives of the formula I for use as self-tanning substance or for increasing melanin synthesis, improving melanin transport and/or improving the distribution of melanin in suprabasal layers, and to preparations comprising these phenyl ketone derivatives.

A personal care 100% plant derived, biodegradable solid granules that sustain beneficial essential oils, and or plant/herbal extracts and emulsify in water to create an emulsified therapeutic solution is disclosed. This invention improves over existing liquids in that its solid granule form is completely plant derived and biodegradable and can sustain essential oils and antioxidants without the requirement of chemical preservatives, and can be packaged in eco-friendly water soluble film and compostable paper. It improves over existing solid forms in that it is a 100% water soluble granule that emulsifies easily in water to form an easy to use liquid product.

The invention relates to a compatible solute or a solute mixture, as well as to a composition comprising the solute or solute mixture, for use in the prevention or treatment of cosmetic or pathologic efflorescences caused by airborne particles, such as pigmentation accompanying with skin ageing, and de- or hypopigmentation, hyperpigmentation, as well as alterations accompanying with atrophy in the broadest sense. The solute or solute mixture, as well as the composition comprising the solute or solute mixture comprises at least one compound according to formula I, formula II, physiologically compatible salts of formula I and formula II, stereoisomeric forms of the compound of formula I, formula II, and physiologically compatible salts of the stereoisomeric forms, and the solute mixture comprises at least two of the afore-mentioned compounds, wherein in formula I

The invention includes a diester exhibiting improved hydrolytic stability that is an esterification product of a 1-methylheptyl alcohol and a dicarboxylic acid. In some embodiments, the diester is bis(1-methyl heptyl) butanedioate, bis(1-methyl heptyl) nonanedioate and/or bis(1-methyl heptyl) decanedioate. The diester may be natural and/or not sourced from palm. Also contemplated within the scope of the invention are diesters exhibiting improved hydrolytic stability represented by Formula (I):

##STR00001##

wherein R.sup.1 is chosen from a linear alkyl group containing four to ten carbon atoms. Also included are personal care compositions comprising any of these diesters and methods of preparing a personal care composition using the inventive diesters, and/or methods of altering the tactile impression and/or skinfeel provided to a user by a personal care composition by combining any of the diesters of the invention and at least one personal care component to form a personal care composition; and topically applying the personal care composition to the hair, skin, and/or nails of a user.
