Abstract
A cleaning composition including a terpene such as D-limonene and hydrogen peroxide in a surfactants based aqueous solution. The composition in various specific formulations is a micro-emulsion useful for a variety of materials and for both industrial and household applications.
Claims4
A clear stable liquid micro-emulsion cleanser composition comprising:
- a. from about 0.5% to 10% of a terpene selected from mono- and sesquiterpenes and mixtures thereof;
- b. from about 0.5% to about 10% of a water soluble glycol ether solvent;
- c. from about 0.5% to about 10% of an isopropylamine salt of linear alkyl benzene sulfonic acid as a first anionic surfactant;
- d. from about 0.4% to about 10% of a sodium 1-octane sulfonate as a second anionic surfactant to provide coupling and stability effects;
- e. from about 0.5% to about 10% of an alkyl ethoxylate nonionic surfactant with an HLB of 11 to 15 to approximate the HLB of the terpene solvent;
- f. from about 2.0% to about 22.8% by weight of a 35% by weight aqueous solution of hydrogen peroxide;
- g. from about 0.2% to 4% by weight of a food grade anti-oxidant based on the terpene weight percentage to stabilize the terpene;
- h. from about 1.0% to 5.0% by weight of a polyacrylate-polyalcohol polymer used as a thickening agent;
- and
- i. deionized water.
