Abstract
A cleaning composition with a limited number of natural ingredients contains an anionic surfactant, a nonionic surfactant, a solvent and a short chain syndetic. The cleaning composition can be used to clean laundry, soft surfaces, and hard surfaces and cleans as well or better than commercial compositions containing synthetically derived cleaning agents.
Claims25
A natural heavy duty cleaning composition consisting essentially of:
- a. an anionic surfactant selected from the group consisting of sodium lauryl sulfate, sodium alkyl α-sulfomethyl ester, and combinations thereof;
- b. a hydrophilic syndetic selected from C6 alkylpolyglucoside;
- c. a nonionic surfactant selected from the group consisting of C12 amine oxide, C12-14 amine oxide, C12 amidoamine oxide, C12-14 amidoamine oxide, alkylpolyglucosides having chain lengths greater than C8, and combinations thereof,
- d. a solvent selected from the group consisting of propylene glycol, 1,3-propanediol, ethanol, sorbitol, glycerol and combinations thereof,
- e. a hydrophobic syndetic selected from a fatty acid;
- f. pH 7-13;
- g. optionally an organic chelating agent from the group consisting of 2-hydroxyacids, 2-hydroxyacid derivatives, glutamic acid, glutamic acid derivatives, and mixtures thereof;
- and
- h. optional ingredients selected from glycerol, pH adjusting agents, calcium salts, boric acid or borate, enzymes, dyes, colorants, fragrances, preservatives, fluorescent whitening agents, blueing agents, defoamers, bleaches, thickeners.
