Problems solved by technology

However, what currently use the scrubbing agent of cellulose particles is a mixture of nanocrystalline cellulose and microcrystalline cellulose, wherein the size of nanocrystalline cellulose is much smaller than the size of pores on the human face (80-150 μm on average), and is Long rod shape, may remain in the pores to affect the human body and cause scratches to the skin during use

Embodiment 1

[0026] Take 100g of absorbent cotton (dry) and soak it in 1.0L of 16% sodium hydroxide aqueous solution at room temperature for 2 hours, filter it with suction and squeeze out the excess sodium hydroxide solution to obtain 300g of alkali cellulose (pressing ratio 3:1). Shred into thin strips, age at room temperature for 7 days, then add 25mL of carbon disulfide, shake at room temperature with a speed-regulating oscillator at 200 times / min for 2h, add 800mL of 5% sodium hydroxide aqueous solution, and stir at room temperature for 6h to obtain sulfonation Cellulose viscose. Then add 3L of liquid paraffin and 30g of potassium oleate, stir at 250rpm for 1h, then react at 80°C for 1.5h, then filter with suction and wash with hot water at about 85°C until white, and the particle size distribution is 110-180μm. The spherical cellulose particles accounting for more than 80% are passed through a 100-200 mesh sieve to obtain the white spherical absorbent cotton cellulose particles used ...

Embodiment 2

[0028] Take 100g of absorbent cotton (dry) and soak it in 1.2L of 18% sodium hydroxide aqueous solution at room temperature for 2 hours, filter it with suction and squeeze out the excess sodium hydroxide solution to obtain 500g of alkali cellulose (pressing ratio 5:1). Shred into thin strips, age at room temperature for 7 days, then add 50mL of carbon disulfide, shake at room temperature with a speed-regulating oscillator at 200 times / min for 2h, add 1L of 6% sodium hydroxide aqueous solution, stir at room temperature for 6h to obtain sulfonation Cellulose viscose. Then add 5L of liquid paraffin and 40g of potassium oleate, stir at 250rpm for 1h, then react at 90°C for 1h, then filter with suction and wash with hot water at about 85°C until white, and the particle size distribution in the range of 70-180μm can be obtained. More than 80% of the spherical cellulose particles are passed through a 100-200 mesh sieve to obtain the white spherical absorbent cotton cellulose particle...

Embodiment 3

[0030] Take 100g of absorbent cotton (dry) and soak in 2.0L of 18% sodium hydroxide aqueous solution at room temperature for 5 hours, suction filter and squeeze out the excess sodium hydroxide solution to obtain 500g of alkali cellulose (pressing ratio 5:1), and the alkali cellulose Shred into thin strips, age at room temperature for 15 days, then add 75mL of carbon disulfide, shake at room temperature with a speed-adjusting oscillator at 200 times / min for 5h, add 1.2L of 7% sodium hydroxide aqueous solution, and stir at room temperature for 8h to obtain sulfonium Chemicalized cellulose viscose. Then add 5L liquid paraffin, 70g potassium oleate, stir at 500rpm for 1h, then react at 90°C for 0.5h, then filter with suction and wash with hot water at about 85°C until white, and the particle size distribution is 70-100μm. The spherical cellulose particles accounting for more than 80% are passed through a 100-200 mesh sieve to obtain the white spherical absorbent cotton cellulose p...

Abstract

The invention belongs to the field of daily supplies, and particularly relates to a spherical degreasing cotton cellulose particle and a cleansing cosmetic containing the same. The particle size of the prepared spherical degreasing cotton cellulose particle is 75-150mum, the spherical degreasing cotton cellulose particle is applied to the cleansing cosmetic as an abrasive agent, the cleansing cosmetic with excellent touch feeling and cleansing feeling can be obtained, the abrasive agent is natural in ingredients, cannot cause influence on environment, the size is close to that of pores in theface, the abrasive agent cannot be resided in the skin, and the spherical particle has small irritation feeling, thus being incapable of damaging the skin.

Description

technical field [0001] The invention belongs to the field of daily chemical products, in particular to a spherical absorbent cotton cellulose particle and a cleaning cosmetic containing the cellulose particle. Background technique [0002] There are two common abrasive materials in cleaning cosmetics, one is natural abrasives, such as finely ground fruit cores, natural minerals; the other is synthetic abrasives, mainly plastic particles, such as polyethylene, polystyrene , polyamide or polyester and other fine powders. Natural abrasives lack elasticity, are hard, and mostly have irregular shapes, which can easily cause skin damage during use. After plastic particles flow into rivers, oceans, ponds, etc., they accumulate in fish and shellfish and affect the human body through them. Governments of various countries have issued bans on plastic microbeads. For example, Canada, the United Kingdom, New Zealand, and South Korea officially banned the sale of personal skin care pro...
