Embodiment 1

[0029] Comparison of different pH regulators

[0030] Formula 1: petrolatum 1.5kg, sodium hydroxide 0.2kg, sodium laureth sulfate 18kg, cocamidopropyl betaine 6kg, lauryl glucoside 5kg, cocamide monoethanolamine 2kg, polyquaternium- 7 2kg, acrylic acid (ester) copolymer 6kg, phenoxyethanol 0.6kg, caprylyl glycol 0.4kg, EDTA disodium 0.2kg, panthenol 0.5kg, sodium chloride 0.6kg, essence 0.5kg, deionized water 56.5kg .

[0031] Formula 2: petrolatum 1.5kg, potassium hydroxide 0.2kg, sodium laureth sulfate 18kg, cocamidopropyl betaine 6kg, lauryl glucoside 5kg, cocamide monoethanolamine 2kg, polyquaternium- 7 2kg, acrylic acid (ester) copolymer 6kg, phenoxyethanol 0.6kg, caprylyl glycol 0.4kg, EDTA disodium 0.2kg, panthenol 0.5kg, sodium chloride 0.6kg, essence 0.5kg, deionized water 56.5kg .

[0032] Formula 3: Petrolatum 1.5kg, Triethanolamine 0.2kg, Sodium Laureth Sulfate 18kg, Cocamidopropyl Betaine 6kg, Lauryl Glucoside 5kg, Cocamide Monoethanolamine 2kg, Polyquaternium-...

Embodiment 2

[0045] Selection of different oil components

[0046] Prepare according to the method in Example 1 according to formula one and the following formula in Example 1 respectively:

[0047] Formula 4: a care composition containing spirulina extract, the difference from formula 1 is that petrolatum is replaced by shea butter.

[0048] Formula five: a care composition containing spirulina extract, the difference from formula one is that petrolatum is replaced by white oil.

[0049] Formula 6: a care composition containing spirulina extract, the difference from formula 1 is that petrolatum is replaced by paraffin.

[0050]During the preparation process, it was found that the product of formula 5 would have oil-water separation and instability of the oil phase floating on the liquid surface. After adding shea butter to formula 4, the suspended oil is hard and has a grainy feel when used. It cannot form a thin oil film on the skin surface well, and it is difficult to moisturize the s...

Embodiment 3

[0052] Comparison of the amount of fat added

[0053] Table 2. Formula table of different petrolatum additions

[0054]

[0055] Formula 7 and Formula 8 were prepared according to the method in Example 1 according to the above formulas in parts by weight. The product prepared by Formula 7 has very little suspended petrolatum, and lacks appearance and moisturizing feeling after use; while the product in Formula 8 has too much suspended petrolatum. It was observed that there were agglomeration into large grease particles in about a week. Formulation 1 is good in appearance and stability, and the skin feeling after use is also ideal. Therefore, the preferred petrolatum addition amount of the present invention is 1.5 parts.

Abstract

The invention discloses a care composition containing spirulina extracts and a preparation method thereof. The care composition is prepared from grease, pH regulators, surfactants, thickening agents,preservatives, vitamin, sodium chloride, essence, deionized water and spirulina extracts. The spirulina extracts and the grease added into a product can generate the cooperated moisture preservation effects; a layer of protection film is formed on the skin surface; the percutaneous water loss rate of the skin can be reduced; the stimulus on the skin is reduced.

Description

technical field [0001] The invention relates to the technical field of daily cosmetics, in particular to a care composition and a preparation method thereof. Background technique [0002] With the gradual improvement of people's living standards, nursing products have also undergone various updates.
