An effective amount of active/cyclodextrin complex, in the form of particles having particle sizes below about 12 microns, is incorporated into solid consumer product compositions. The complexes provide fast release of the active when they are wetted even when the amount of water available to effect release of the active is limited as in personal use compositions like drugs, foods, and cosmetics where active release is typically effected by body fluids. Preferred actives include perfumes, flavors, and pharmaceutical materials that are used by consumers.
This is a division of application Ser. No. 08/268,157, filed on Jun. 29, 1994, U.S. Pat. No. 5,552,378 which is a continuation of application Ser. No. 07/707,266, filed May 24, 1991, now abandoned; which is a continuation of application Ser. No. 07/486,757, filed Mar. 6, 1990, now abandoned.
The present invention relates to a process for the preparation of a water soluble inclusion complex of neem seed kernel extract (NSKE) containing azadirachtin-A in cyclodextrin and its use in an insecticidal formulation. The process of the present invention comprises the following steps adding neem seed kernel extract containing azadirachtin-A to cyclodextrin, the molar ratio of azadirachtin-A to the cyclodextrin ranging from 1:0.5 to 1:20, stirring the above mixture, filtering the above mixture to obtain a water soluble inclusion complex of neem seed kernel extract, if desired, freeze/spray drying the said water soluble complex of neem seed kernel extract to get a free flowing pale cream powder.
A lipstick is provided for freshening the breath and reducing oral malodor. These lipsticks are based on a combination of free menthol and a bound menthol substance, the latter being either a complex or an encapsulated form. Most preferred is a menthol complex with beta-cyclodextrin. Further components of the lipstick include lipophilic material such as waxes and usually colorants. Water is advantageously included at levels ranging up to 10% by weight.
An ambient stable tea based beverage that contains a tea extract and a preservative system. The preservative system contains cinnamic acid, one or more essential oils and one or more pasteurization adjuncts that become fungicidal when activated by heat.
A lipstick is provided for freshening the breath and reducing oral malodor. These lipsticks utilize an antibacterial agent in combination with menthol as the active components. Most preferred as the antibacterial agent are zinc salts, especially zinc citrate. Further components of the lipstick include a lipophilic material such as waxes and usually colorants. Water may be included at levels ranging up to about 25% by weight.
The dry composition has 50% w/w oil which contains polyunsaturated fatty acids such as omega-3 and/or omega-6 fatty acids, and 50% w/w of a starch based matrix. The starch based matrix has 70% by weight or more of a starch hydrolysate with a DE of 20-100 and a converted starch such as a thin boiled starch or a maltodextrin. The matrix can contain up to 15% of a cyclodextrin or lecithin. The composition is stable over time and is especially suited for use with food.
